JPG to PDF Converter
The JPG to PDF Converter turns JPEG images into PDF documents. Upload one or multiple JPG files, configure the page size, orientation, margin, and whether to merge all images into a single PDF or produce separate files — then click Convert to PDF and download the result. The tool processes all conversion options in the browser with no software installation required.
JPG to PDF conversion is one of the most common document tasks for anyone who scans physical documents with a phone camera, takes photos of receipts or invoices, captures screenshots, or needs to submit images as a formal attachment. A PDF is universally readable, maintains consistent layout on any device, and is accepted by almost every submission system.
How to use the JPG to PDF Converter
- Click Select a File or drag and drop your JPG or JPEG images into the upload area. You can upload multiple images at once — guest users up to 5 images (10 MB each), registered users up to 20 images (40 MB each).
- Set the page size, orientation, and margin using the options panel. The settings reference table below explains every option and when to use each one.
- If you uploaded multiple images, choose whether to merge them all into one PDF file or generate a separate PDF for each image. The Merge toggle controls this.
- Set the correct page order. The output PDF follows the sequence of images as displayed. Drag thumbnails to reorder if the tool supports it, or rename files numerically (01-, 02-, 03-) before uploading to control order via alphabetical sort.
- Click Convert to PDF. Download the result and confirm the page size, order, and image quality are correct before sending or submitting.
Conversion settings — what each option does
The tool provides four groups of settings that control how your images are placed on the PDF pages. Choosing the right combination for your use case makes the difference between a professional document and a poorly formatted one:
| Setting | Option | When to use it |
| Page Size | ||
| Page Size | Fit (same page size as image) | The PDF page is sized to exactly match the image dimensions. No white space is added around the image. Best for photos being archived or shared as they were captured, and for images of unusual or non-standard sizes. The PDF page dimensions will vary per image if you convert multiple files. |
| Page Size | A4 (297 × 210 mm) | All images are placed on standard A4 pages. The image is scaled to fill the page. Use this for documents intended to be printed on standard European or international paper, submitted to systems that expect A4, or for professional reports and formal correspondence. A4 is the standard in most countries outside North America. |
| Page Size | US Letter (215.9 × 279.4 mm) | All images are placed on US Letter pages. Use this for documents intended for printing in the United States, Canada, or Mexico, or for submission to US-based academic institutions, courts, or businesses that expect Letter-size pages. |
| Page Orientation | ||
| Orientation | Automatic | The tool detects each image's dimensions and selects portrait (for images taller than wide) or landscape (for images wider than tall) automatically. This is the most practical setting for mixed batches of images with different orientations. Recommended for most users. |
| Orientation | Portrait | All PDF pages are set to portrait orientation regardless of image dimensions. Wide images will be scaled down to fit within portrait bounds, leaving empty space at the sides. Use when all your images are portrait-oriented or when the recipient requires a consistent portrait layout. |
| Orientation | Landscape | All PDF pages are set to landscape orientation. Tall images will be scaled down to fit within landscape bounds. Use for wide-format content such as spreadsheet screenshots, panoramic photos, or presentation slides. |
| Margin | ||
| Margin | No Margin | The image fills the entire page with no white border. Best for photos, scanned documents where every part of the image contains content, and any situation where you want the image to use the full page area. |
| Margin | Small Margin | A narrow white border (approximately 0.5 inch / 12 mm) is added around the image. Use this for documents that will be printed and handled — the margin gives something to hold without covering content. Also more visually comfortable for reading. |
| Margin | Big Margin | A wide white border (approximately 1 inch / 25 mm) is added around the image. Use this for formal or professional documents, submissions that require standard margins, or for presentations where the image should sit cleanly centered on the page. |
| Merge into single PDF | ||
| Merge | Enabled (checked) | All uploaded images are combined into a single PDF file, one image per page, in the order you set. The single PDF is downloaded in one file. Use this when your images represent pages of the same document — a multi-page scanned form, a set of receipts for one submission, an assignment with multiple pages. |
| Merge | Disabled (unchecked) | Each image is converted to its own individual single-page PDF. You receive multiple separate PDF files. Use this when each image is an independent document and you want separate files — individual product photos, separate identity document scans, individual certificates. |
For most everyday use cases — scanned documents, receipts, homework, form submissions — the recommended defaults are: A4 or US Letter page size (matching your country's standard), Automatic orientation (lets the tool detect portrait vs landscape per image), Small margin (keeps content readable when printed), and Merge enabled (produces one combined PDF). These four settings cover the majority of real-world conversion needs without requiring adjustment.
Common use cases and recommended settings
| Scenario | Recommended settings | Why |
| Scanned multi-page document (receipts, forms, ID pages) | Page size: A4 or US Letter. Orientation: Automatic. Margin: Small. Merge: Enabled. | Standard page size produces a consistent document. Small margin keeps content readable when printed. Merge into one PDF ensures the entire document is one file, not loose separate images. |
| Single photo or image for sharing or archiving | Page size: Fit. Orientation: Automatic. Margin: No Margin. Merge: N/A (single image). | Fit preserves the image's exact dimensions without forcing it into a standard page size. No margin ensures the photo uses the full page. Automatic orientation matches how the photo was taken. |
| School or university submission | Page size: A4 (EU/international) or US Letter (North America). Orientation: Portrait. Margin: Small or Big. Merge: Enabled. | Academic institutions and submission portals almost always expect standard page sizes with margins. Portrait is the standard for written work. Merge produces one submission file. |
| Presentation slides or screenshots | Page size: Fit or A4. Orientation: Landscape. Margin: No Margin or Small. Merge: Enabled. | Landscape matches the natural aspect ratio of screenshots and slide images. Fit or A4 with landscape produces a clean wide-format page. |
| Product photos for a catalogue or invoice | Page size: A4. Orientation: Automatic. Margin: Big. Merge: Enabled or Disabled depending on whether one catalogue PDF or separate product sheets is needed. | A4 is the standard for business documents. Big margin frames each photo professionally, giving the page a clean catalogue look. |
| Passport, ID, or official document scan | Page size: Fit or A4. Orientation: Automatic. Margin: Small. Merge: Disabled (keep each document as a separate file). | Official document scans are usually submitted as individual files. Keeping them separate avoids combining documents in the wrong order. Small margin avoids cropping important edges. |
Image quality — how it affects the PDF output
The PDF output can only be as sharp and readable as the original JPG image. The conversion process places each image onto the PDF page at its original quality — it does not enhance, sharpen, or improve low-quality photos. Understanding what affects image quality helps you get the best result:
Resolution and sharpness
A photo of a text document taken at arm's length with a modern smartphone produces a high enough resolution for clear, readable PDF output. Blurry, out-of-focus, or low-light images will produce equally blurry PDF pages. If the text in the original photo is readable on screen, it will be readable in the PDF. If it is not, the PDF will also be unreadable — conversion does not correct focus or clarity.
JPG compression and artefacts
JPG uses lossy compression: each time a JPG file is saved, some image quality is discarded. Images that have been compressed multiple times, or images saved at a high compression (low quality) setting, will show visible artefacts — blocky patches, smearing around text edges, and loss of fine detail. For scanned text documents where readability is important, use the lowest compression (highest quality) setting on your camera or scanner, or consider using the Image to PDF tool to convert in PNG format, which is lossless and produces sharper text edges.
Lighting and contrast
Photos taken in poor lighting produce images with low contrast and indistinct text. For phone-camera document scans, use even, bright lighting (natural daylight from a window is ideal), hold the camera directly above the document to avoid perspective distortion, and ensure the document lies flat. Most modern smartphones have a document scan mode in their camera or Files app that automatically corrects perspective and improves contrast — using this before converting produces significantly better PDF output.
Large, high-resolution JPG images produce large PDF files. A single phone camera photo taken at full resolution (12–50 megapixels) can be 3–8 MB. Merging 10 such photos into one PDF can produce a 30–60 MB file that exceeds email attachment limits. Before converting large batches of high-resolution photos, resize them to a practical resolution for your intended use — 150 DPI is generally sufficient for on-screen reading, 300 DPI for clear print output. Image editing apps and Windows/macOS photo tools can resize images before you upload.
JPG vs other image formats — which produces better PDF output
| Format | Compression | Best for converting to PDF — and when to prefer a different format |
| JPG / JPEG | Lossy compression. Smaller file size at the cost of some image quality — fine for photos but creates visible artefacts on sharp edges and text. | Best for photographs, scanned photo documents, and any image-based content where color variation is more important than edge sharpness. For scanned text documents where readability matters most, a higher quality JPG (low compression setting) or a lossless format like PNG produces better results. |
| PNG | Lossless compression. File sizes are larger than JPG for photos, but smaller for images with large areas of flat color and sharp edges. | Best for screenshots, computer-generated diagrams, presentations, and scans of text-heavy documents. PNG preserves text edges perfectly. If your image is a screenshot or has significant text content, PNG produces a sharper, more readable PDF than JPG. |
| TIFF | Uncompressed or lossless. Very high quality but large file sizes. | Best for archival-quality scans and professional print workflows. TIFF is typically used by scanners set to archival quality. Converting TIFF to PDF produces very large files. Use the Image to PDF tool (linked below) for TIFF conversion. |
| BMP | Uncompressed. Very large files, no quality loss. | BMP files are uncompressed Windows bitmap images. Large file sizes make them impractical for most workflows. Use the Image to PDF tool for BMP conversion. |

Frequently asked questions
What is the difference between JPG and JPEG?
JPG and JPEG are the same format — there is no technical difference. JPEG stands for Joint Photographic Experts Group, the organization that developed the format. The file extension is .jpeg in its full form and .jpg in the shortened form used on Windows systems, which historically limited file extensions to three characters. Both .jpg and .jpeg files are identical in structure and quality and are handled the same way by all tools and operating systems. This converter accepts both.
Can I convert multiple JPG images into a single PDF?
Yes. Upload multiple JPG files, arrange them in the correct order (drag to reorder, or number filenames before uploading), and enable the 'Merge all images in one PDF' option before clicking Convert. The tool produces one PDF file with each image on a separate page in the sequence you set. If you leave Merge disabled, each image is converted to its own individual single-page PDF.
Which page size should I choose — Fit, A4, or US Letter?
Use Fit if you want the PDF page to match the exact dimensions of your image — ideal for photos and images of non-standard sizes that do not need to conform to a print format. Use A4 if the PDF will be printed, submitted, or distributed in Europe, Asia, or any region where A4 is the standard paper size (most of the world outside North America). Use US Letter if the document will be used in the United States, Canada, or Mexico, or submitted to a US institution, court, or business.
Will my image quality change after conversion?
The conversion embeds your JPG images in the PDF at their original quality — it does not compress, enhance, or alter the images. The PDF output will look the same as the original JPG files. If the source images are blurry, dark, or low resolution, the PDF will be too. For the best results, ensure source photos are sharp, well-lit, and taken at full camera resolution. If the resulting PDF is too large to email, use the PDF Compressor to reduce file size, or resize images to a lower resolution before converting.
What is the 'Automatic' orientation setting?
Automatic orientation detects each image's aspect ratio and selects portrait (tall) or landscape (wide) page orientation accordingly. If an image is taller than it is wide, the page is set to portrait. If wider than tall, the page is set to landscape. This is the most practical setting for a batch of images with varying orientations. Selecting Portrait or Landscape forces all pages to that orientation regardless of image dimensions — some images may be scaled down to fit, leaving empty space on the page.
Why is my converted PDF file very large?
PDF file size when converting images is determined primarily by the size of the source JPG files. High-resolution phone camera photos (12–50 megapixels) produce large PDF files, especially when merging many images. To reduce the output PDF size: (1) resize source images to a lower resolution before uploading — 150 DPI is sufficient for screen reading, 300 DPI for print; (2) use the PDF Compressor on the resulting file; or (3) reduce the JPG compression quality setting on your camera or scanner before taking the photos.
Can I convert a PDF back to JPG?
Yes — use the ToolsPiNG PDF to JPG converter, which extracts PDF pages as individual JPG images. This is the reverse operation: PDF to JPG produces one image file per PDF page, while JPG to PDF produces one PDF page per image file.
Is the JPG 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, 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.
