Image to PDF Converter
The Image to PDF Converter turns image files into PDF documents. It accepts all common image formats — JPG, PNG, WebP, GIF, BMP, and TIFF — in a single session. Upload images in any combination of formats, set the page size, orientation, margin, and whether to merge all images into one PDF, then click Convert to PDF and download the result.
This is the broadest image-to-PDF tool in the ToolsPiNG PDF suite. When your images are all in the same format, the format-specific tools (JPG to PDF, PNG to PDF, GIF to PDF, BMP to PDF, TIFF to PDF) provide additional format-specific guidance. When you have images in different formats that need to become one PDF — a mix of phone camera JPGs, desktop PNG screenshots, and WebP images downloaded from the web — this is the right tool.
How to use the Image to PDF Converter
- Click Select a File or drag and drop your image files into the upload area. You can mix formats freely in one session — JPG, PNG, WebP, GIF, BMP, and TIFF can all be uploaded together. Guest users can upload up to 5 images (10 MB each); registered users up to 20 images (40 MB each).
- Arrange images in the correct page order. The output PDF follows the sequence shown. Rename files with numeric prefixes (01-, 02-, 03-) before uploading to control order via alphabetical sort, or drag thumbnails to reorder if the tool supports it.
- Configure the page size, orientation, and margin. The settings reference table below explains every option.
- Enable Merge to combine all images into a single PDF. Disable it to produce a separate PDF per image.
- Click Convert to PDF. Download and review the result — check page order, image quality, and orientation — before sharing or submitting.
Supported image formats — reference guide
The tool accepts six image formats. Each has different characteristics that affect the PDF output quality and file size. The table below covers all supported formats with a link to each format's dedicated conversion page for deeper guidance:
| Format | Type | Key characteristic | Best for converting to PDF | Format-specific guide |
| JPG / JPEG | Lossy | Lossy compression. Excellent for photographs; produces artefacts on text and sharp edges at high compression. | Photographs, camera images, scanned photo documents. The most common image format for everyday document conversion. | JPG to PDF |
| PNG | Lossless | Lossless compression with full colour depth and alpha channel transparency. Preserves every pixel exactly. | Screenshots, UI designs, diagrams, charts, and any image containing text or sharp-edged graphics. Produces the sharpest PDF output for these content types. | PNG to PDF |
| GIF | Lossless (256 colours) | Limited to 256 colours per frame. Lossless within that palette. Supports animation (converted to a static frame in PDF). | Simple logos, icons, flat-colour graphics. Not recommended for photographs or gradients. Animated GIFs are converted to a single static frame. | GIF to PDF |
| BMP | Uncompressed | Raw pixel data, no compression. Very large file sizes. Produced by older scanners, Windows Paint, and legacy systems. | Legacy document scans, archive images, Windows application exports. Convert BMP to PNG first if files exceed the upload limit. | BMP to PDF |
| TIFF / TIF | Multiple (LZW, uncompressed, CCITT Group 4...) | Professional archival format. Supports multiple compression types. Uniquely: a single TIFF file can contain multiple pages. | High-quality document scans, fax archives, medical and legal records. Multi-page TIFFs produce multi-page PDFs automatically. | TIFF to PDF |
| WebP | Lossy or lossless | Modern format developed by Google. Produces smaller files than JPG at equivalent quality (lossy mode) or smaller than PNG at equivalent quality (lossless mode). Supports alpha channel transparency. | Web graphics, images downloaded from modern websites, screenshots from browsers that save in WebP. Increasingly common as default export format from Chromium-based browsers. | Image to PDF (this tool) |
WebP — the format not covered on individual format pages
WebP is a modern image format developed by Google and now supported natively by all major browsers. It is increasingly common as the default export format from design tools, the format used by images downloaded or saved from websites in Chromium-based browsers (Chrome, Edge, Opera, Brave), and the format used by modern web applications for image assets.
WebP comes in two modes. Lossy WebP achieves smaller file sizes than equivalent-quality JPG — typically 25–35% smaller. Lossless WebP achieves smaller files than equivalent-quality PNG — typically 26% smaller. Both modes support alpha channel transparency, unlike JPG. WebP produces excellent PDF output: images are sharp, colors are accurate, and file sizes are manageable. If you have downloaded images from websites and they have a .webp extension, upload them directly — no conversion to another format is needed first.
WebP images saved from websites in older versions of Windows may sometimes be saved without the .webp file extension, or may appear with the wrong extension. If a WebP file is not uploading correctly, try renaming it to add the .webp extension explicitly, or open it in any modern image editor and re-export as PNG or JPG before uploading.
Converting mixed-format image batches
The primary advantage of Image to PDF over the individual format tools is mixed-format batch support. A real document might consist of phone camera photos (JPG), scanned attachments (TIFF from the flatbed scanner), a design mockup (PNG), and web reference images (WebP). Processing these separately and merging the results is more steps than converting all at once in one session.
| Mixed-batch scenario | Recommended approach |
| Scanned document pages (TIFF) alongside photographs (JPG) | Upload all files together and enable Merge. Use Automatic orientation to handle portrait document pages and landscape photo pages differently. Use A4 or US Letter page size for consistency. Small margin improves readability for both content types. |
| Screenshots (PNG) with annotated photos (JPG) | Upload all files together and enable Merge. PNG and JPG are both fully supported and will be placed on pages in the sequence you upload them. Use Landscape for screenshot-heavy batches (most desktop screenshots are wider than tall). Automatic orientation handles the mix correctly. |
| Design exports (PNG) with product photos (JPG or WebP) | Use Fit page size to preserve each image's exact dimensions — design mockups and product photos typically have intentional proportions that should not be scaled to a standard paper size. Enable Merge for a single review document. |
| Legacy scans (BMP) to archive alongside modern scans (JPG or PNG) | Upload all together and enable Merge. Note that BMP files are much larger than equivalent JPG or PNG files — ensure BMP files are within the upload limit. Use Automatic orientation and A4 or US Letter for consistent archival document sizing. |
| Web-downloaded images in multiple formats (JPG, PNG, WebP) | Images downloaded from websites may be in different formats depending on the browser and website. Upload all formats together — Image to PDF handles WebP, PNG, and JPG in the same session. Enable Merge to combine them all. |
When mixing BMP files with other formats, be aware that BMP files are significantly larger than equivalent JPG, PNG, or WebP files. A single A4-page BMP scan at 300 DPI is approximately 25 MB — larger than the 10 MB guest upload limit. If BMP files exceed the limit, convert them to PNG first (Windows Paint: File → Save As → PNG) and upload the PNG versions alongside your other images. PNG is lossless — the quality is identical — but the file is 70–88% smaller.
Conversion settings — what each option does
| Setting | Option | When to use it |
| Page Size | ||
| Page Size | Fit (same page size as image) | The PDF page is sized to match the exact pixel dimensions of each image. Use for images that should not be rescaled — screenshots, UI mockups, diagrams where precise proportions matter, or photos being archived at their native resolution. |
| Page Size | A4 (297 × 210 mm) | All images are placed on A4 pages. Use for documents intended for printing or distribution in Europe, Asia, Australia, and internationally. The default choice for professional, academic, and business documents outside North America. |
| Page Size | US Letter (215.9 × 279.4 mm) | All images are placed on US Letter pages. Use for documents intended for distribution in the United States, Canada, or Mexico, or submission to US institutions. |
| Page Orientation | ||
| Orientation | Automatic | Detects each image's aspect ratio and applies portrait (taller than wide) or landscape (wider than tall) per image. The best choice for mixed batches — a set of document scans alongside screenshots will have the correct orientation applied to each automatically. |
| Orientation | Portrait | Forces all pages to portrait orientation. Use when all images are portrait-oriented or when the destination system requires a consistent portrait layout. |
| Orientation | Landscape | Forces all pages to landscape orientation. Use for wide-format content: desktop screenshots, presentation slides, wide charts, and horizontal diagrams. |
| Margin | ||
| Margin | No Margin | The image fills the entire page edge to edge. Best for full-page photos, design exports, and images where every pixel is content and a white border would be distracting. |
| Margin | Small Margin | A narrow white border (~0.5 inch / 12 mm) surrounds the image. A practical default for most document use cases — scanned documents, reports, and submissions. Improves readability when printed. |
| Margin | Big Margin | A wide white border (~1 inch / 25 mm). Use for formal submissions, legal documents, academic papers, and any context where standard document margins are expected or required. |
| Merge into single PDF | ||
| Merge | Enabled (checked) | All uploaded images are combined into one PDF, one image per page, in the order you set. The defining feature of this tool — when you upload a mixed batch of JPGs, PNGs, and WebPs from the same document, Merge creates one clean PDF from all of them. |
| Merge | Disabled (unchecked) | Each image is converted to its own individual single-page PDF. Use when each image is an independent document and should be delivered as a separate file. |
Common use cases and recommended settings
| Scenario | Recommended settings | Notes |
| Multi-format document submission (job application, portfolio) | Page size: A4 or US Letter. Orientation: Portrait. Margin: Small. Merge: Enabled. | A job application or portfolio may combine a JPG photo, PNG screenshots of work, and scanned PDF pages from different sources. Image to PDF handles all image formats in one step. Use Merge PDF afterward to combine the image-converted PDF with any existing PDF documents. |
| Scanned receipts or invoices from phone camera (JPG) and flatbed scanner (TIFF) | Page size: A4. Orientation: Automatic. Margin: Small. Merge: Enabled. | Phone camera photos are JPG; flatbed scanner output is typically TIFF. Upload both in the correct sequence and enable Merge. Automatic orientation handles portrait receipts and landscape invoices correctly. |
| Design review pack (PNG mockups + WebP reference images) | Page size: Fit. Orientation: Automatic. Margin: No Margin or Small. Merge: Enabled. | Fit preserves the exact pixel dimensions of each design asset. WebP images downloaded from reference sites or design tools are accepted natively alongside PNG exports. |
| Academic submission with figures in different formats | Page size: A4. Orientation: Automatic. Margin: Big. Merge: Enabled. | Academic figures are often in different formats: JPG photographs, PNG diagrams, TIFF from specialist imaging equipment. Big margin matches standard academic document formatting. Merge creates one submission file. |
| Bug report with screenshots and supporting photos | Page size: Fit or A4. Orientation: Landscape. Margin: Small. Merge: Enabled. | Bug reports typically combine PNG desktop screenshots (landscape) with JPG photos of hardware or physical states. Landscape orientation is correct for most screenshot content. Merge creates one coherent report. |
When to use a format-specific tool instead
Each image format supported here has its own dedicated conversion page with format-specific guidance, troubleshooting, and deeper technical explanation. Use the format-specific tools when:
- You are converting only JPG files and want guidance on page settings for photographs — JPG to PDF.
- You are converting PNG files and need to understand transparency handling, or you want the PNG vs JPG quality comparison — PNG to PDF.
- You are converting animated GIFs and need to know which frame will appear in the PDF output — GIF to PDF.
- You are converting BMP files and need the PNG conversion workaround for large files — BMP to PDF.
- You are converting multi-page TIFF files (fax archives, scanned legal documents, medical records) and need to understand how multi-page extraction works — TIFF to PDF.

Frequently asked questions
What image formats does the Image to PDF Converter support?
The tool accepts JPG (JPEG), PNG, WebP, GIF, BMP, and TIFF (TIF) files. All six formats can be uploaded in the same session and mixed freely in a batch. TIFF accepts both .tif and .tiff file extensions. The tool handles multi-page TIFF files automatically — each page in a multi-page TIFF becomes a separate page in the output PDF. For format-specific technical guidance, each format has its own dedicated conversion page linked in the format reference table above.
Can I mix different image formats in one PDF?
Yes — this is the primary use case for this tool. Upload JPG, PNG, WebP, GIF, BMP, and TIFF files in any combination, in the correct sequence, and enable the Merge toggle. The tool converts all formats and places each image on its own PDF page in the order you set. The resulting PDF contains pages from different source formats seamlessly — there is no visible difference between a page from a JPG source and a page from a PNG source in the output.
What is WebP and why would I have WebP images?
WebP is a modern image format developed by Google that is native to all Chromium-based browsers (Chrome, Edge, Brave, Opera). It is increasingly common for several reasons: images saved or downloaded from websites in Chrome or Edge are often saved as WebP; modern web applications and design tools export in WebP by default; and many CDNs and web servers serve images in WebP format for better performance. WebP supports both lossy and lossless compression and full alpha channel transparency. The Image to PDF Converter accepts WebP natively — no conversion to another format is needed before uploading.
Why does the Image to PDF page accept WebP when the individual format pages do not?
WebP is supported by this tool but does not have its own dedicated format page because it has no conversion-specific quirks that require a separate guide. JPG has lossy artefacts on text. PNG has alpha channel transparency that requires explanation. GIF has animation and 256-colour limits. BMP has enormous file sizes. TIFF has multi-page capability and variable compression. WebP converts cleanly to PDF with full color and transparency support, behaves predictably, and does not require special handling. It is covered in the format reference section on this page.
Should I use Image to PDF or a format-specific tool?
Use Image to PDF when your batch contains images in more than one format, or when you simply want one tool that handles everything. Use the format-specific tools (JPG to PDF, PNG to PDF, etc.) when you have a single-format batch and want format-specific guidance — particularly for animated GIFs (which frame appears), transparent PNGs (what happens to transparency), multi-page TIFFs (how pages are extracted), and large BMP files (the PNG workaround for oversized files).
What is the 'Merge' option and should I enable it?
The Merge toggle controls whether all uploaded images are combined into one PDF (Merge enabled) or each image is converted to its own separate PDF (Merge disabled). For most document conversion tasks — scanned documents, homework submissions, mixed-format reports, photo bundles — Merge should be enabled. This produces one clean PDF from all your images. Disable Merge only when each image is an independent document that should be delivered as a separate file, such as individual product photos that each need their own PDF.
How do I control the order of pages in the merged PDF?
The output PDF follows the sequence of images as displayed in the upload area. To control order: rename your files with numeric prefixes before uploading (01-first-page.jpg, 02-second-page.png, 03-third-page.tiff). When you browse for files and select multiple at once, they are presented alphabetically — and alphabetical order with numeric prefixes equals the intended numeric order. This is the most reliable method for ensuring correct page sequence across all browsers and operating systems.
Is the Image to PDF Converter free?
Yes. The converter is free within the daily usage limits shown above. Guest users can run 25 conversion sessions per day and upload up to 5 images per session (10 MB each) without creating an account. Registering a free ToolsPiNG account increases the daily limit to 100 sessions, the file size limit to 40 MB per image, and the per-session image count to 20.
