How to convert JPG to PDF
- Add your images. Choose one or many JPG, PNG, WebP, GIF or BMP files, or drag them onto the box. Each image becomes one page.
- Put them in order with the up and down arrows, and remove any you do not need.
- Choose the page layout. A4 is standard in most of the world and US Letter in the US and Canada. "Same as image" makes each page exactly the size of its photo, with no white border. Automatic orientation turns the page landscape for wide images and portrait for tall ones.
- Press Convert to PDF and download your file.
Image quality and file size
JPG and PNG files are placed into the PDF exactly as they are, without being compressed again, so there is no loss of quality. The PDF is therefore roughly the same size as all your images added together. Images in other formats, and phone photos that are stored sideways with a rotation tag, are decoded by your browser and saved as high-quality JPEG so that they appear the right way up. If the final PDF is too big to email or upload, run it through Compress PDF.
Tips for scanning documents with your phone
- Lay the page flat in good, even daylight and hold the phone directly above it to avoid shadows and slanted edges.
- Crop each photo to the edge of the paper before converting. Most phones have a crop button in the photo editor.
- Use A4 or Letter with a small margin for documents you will print, and "Same as image" for photo albums, artwork and screenshots.
- Keep pages in order by taking the photos in order. Most phones name files by time, so they appear in the right sequence.
Common uses
Students turn photos of handwritten homework into one PDF for an online class. Job seekers convert photographed certificates for application portals. Online sellers combine product photos, a size chart and care instructions into a single file for wholesale buyers. To add an existing PDF to your converted photos, use Merge PDF. To go the other way and turn PDF pages into pictures, use PDF to JPG.
How this tool works
This tool runs entirely in your web browser using two well-known open-source libraries: pdf-lib, which creates and edits PDF files, and Mozilla's PDF.js, the engine Firefox uses to display PDFs. Both are hosted on our own site, so your browser does not contact any other service while you work. Because the files never leave your device, the tool works for private documents such as contracts, bank statements and ID scans, and it keeps working even on a slow connection once the page has loaded. Very large files depend on your device's memory: a modern phone can usually handle a few hundred pages, and a computer can handle much more.

Frequently asked questions
Can I convert several JPG images into one PDF?
Yes. Add as many images as you like. Each one becomes a page, in the order shown in the list, and you can change the order with the arrow buttons.
Does converting to PDF reduce image quality?
No. JPG and PNG files are embedded exactly as they are. Other formats and rotated phone photos are converted to high-quality JPEG first.
Can I convert HEIC iPhone photos?
Only in browsers that can open HEIC images, such as Safari on a Mac or iPhone. In other browsers, set your iPhone camera to 'Most Compatible' (JPG) or export the photos as JPG first.
Are my photos uploaded?
No. The PDF is created in your browser, and your images never leave your device.
Which page size should I choose?
Choose A4 if you are outside North America, US Letter in the US and Canada, or 'Same as image' if you want no white border around each picture.
