Combine images into one PDF
🔒 Your files never leave your device
Pick your JPGs or PNGs, put them in order, and get a single PDF. No account, no upload, no watermark.
or drop them here — you can select several at once
JPG, PNG, WebP, GIF, BMP
The order here is the page order in the PDF. Use the arrows to change it.
Page size, and when to ignore it
The default is A4 with a medium margin, which is what you want when the PDF is going to be printed or attached to an application form. Every image is scaled to fit inside the page and centred, and the aspect ratio is never distorted.
If the PDF is only ever going to be read on a screen — a set of screenshots, a comic, a scanned document you just want in one file — choose Fit to image instead. That makes each page exactly the size of its image, so there are no white borders and nothing is scaled at all.
One deliberate behaviour worth knowing: an image smaller than the page is never enlarged to fill it. Blowing up a 400-pixel-wide screenshot to A4 does not add detail, it just makes the blur bigger. It stays at its natural size, centred.
Which formats work
The PDF format itself only accepts JPEG and PNG as embedded images. Anything else — WebP, GIF, BMP, and HEIC on Safari — is converted to PNG in your browser first, and the tool tells you which files it converted. PNG is used for the conversion rather than JPEG so that transparency survives.
That conversion is lossless in the sense that no extra JPEG compression is applied, but it can make the PDF noticeably larger, because PNG is not efficient for photographs. If you are combining a lot of WebP photos and the file size matters, converting them to JPEG first will give you a much smaller PDF.
Common uses
- Applications and claims — receipts, ID scans, and certificates that a form insists on receiving as one PDF rather than five photos.
- Sending photos of a document — you photographed several pages with your phone and need to send them as a single readable file.
- Screenshots into a report — with "Fit to image", the screenshots keep their exact pixel dimensions.
- Printing — A4 or Letter with a margin, so nothing gets clipped at the edge of the paper.
Questions
Does the order matter?
Yes — the list order is the page order. Use the arrows to move a file up or down. Files are added in the order you selected them, which is not always the order you expected.
Is the image quality reduced?
JPEGs and PNGs are embedded exactly as they are, with no re-encoding. Other formats are converted once to PNG, which does not add compression artefacts.
Is there a limit on how many images?
Only your device's memory. Everything is held in the browser, so a hundred high-resolution photos will use a lot of RAM on a phone.
