About the Image to PDF tool
Photos and screenshots are easy to take but awkward to send as a set. Turning them into a single PDF makes them easier to print, archive, and email as one attachment instead of many. The Image to PDF tool converts JPG and PNG images into a PDF, one image per page, entirely on your device.
The two layout choices this tool offers — matching each image's own size, or fitting it onto a standard A4 page — solve two different problems. Matching the image's own dimensions keeps a photo looking exactly as it was framed, edge to edge, which suits a design proof or a photo you plan to print at its native size. Fitting to A4 instead centers the image with a margin on a standard page, which is usually the better choice for anything you expect someone to print on a home or office printer, since it matches the paper they're likely loading into the tray.
How to convert images to PDF
- Upload the JPG or PNG images you want to convert, in the order you want them to appear.
- Choose whether each page should match the image's own dimensions, or fit onto a standard A4 page.
- Remove any image you don't want included using the Remove link.
- Click Convert to PDF to download the finished file.
Tips for best results
- Take photos of documents in good, even light and directly overhead where possible — the conversion itself doesn't correct perspective or lighting, so the clearer the source photo, the more readable the final PDF page will be.
- If you're combining many photos taken on a phone, check they're all the same orientation (all portrait or all landscape) before uploading; mixing the two is fine but the pages will alternate shape, which can look inconsistent when printed.
- Use "match image size" for anything meant to be viewed on screen, and "fit to A4" for anything meant to be printed, since it accounts for standard printer margins automatically.
- Large, high-resolution photos (many megabytes each from a modern phone camera) will produce a correspondingly large PDF; if file size matters more than image sharpness, run the result through Compress PDF afterward.
Common ways people use this
- Turning photos of receipts into a single PDF for an expense report.
- Combining scanned handwritten notes into a shareable document.
- Converting a set of whiteboard photos from a meeting into one file.
- Assembling product photos into a simple catalog PDF.
- Archiving photos of a physical document (a certificate, an ID, a signed form) as a single searchable-by-name PDF rather than loose image files.
Good to know
This tool places one image per page and doesn't crop, rotate, or straighten photos automatically — if a photo was taken at an angle or upside down, straighten it in your phone's photo editor before uploading, or convert it first and then use the Rotate PDF tool on the result.
Frequently asked questions
Which image formats are supported?
JPG and PNG. If you have a different format like HEIC, convert it to JPG or PNG first using your phone or computer's built-in tools.
Will image quality be reduced?
The images are placed into the PDF at their original resolution; choosing the A4 fit option only scales the page layout, not the image data itself.
Can I mix JPG and PNG files in one PDF?
Yes, you can upload any combination of the two formats and they'll be combined into the same document.
Can I control the order of the pages?
Pages follow the order the files were added in; remove and re-add a file if you need to move it, or select images from your file browser in your preferred order.
Can I add a caption or text under each image?
Not directly in this tool. Convert the images to a PDF first, then use Add Page Numbers or a PDF editor if you need to layer text onto the pages afterward.
Why is my resulting PDF quite large?
Modern phone cameras produce large image files, and this tool preserves that resolution rather than compressing it, so quality stays high. If the file size is a problem for emailing, run it through Compress PDF afterward.
