Turning photographs into a document
The usual reason to be here: you have photographed several sheets of paper with a phone and you need one PDF to send.
Add all the photographs at once, put the list in the right order, and build. Each image becomes a single page, sized to the image itself rather than forced onto a fixed paper size, so nothing is cropped and nothing is letterboxed.
Why doing this locally matters
The documents people photograph are rarely trivial. Passports, driving licences, bank statements, signed contracts, medical forms, proof of address.
Every mainstream online JPG-to-PDF tool asks you to upload all of that to a server. Here the document is assembled inside your browser with pdf-lib, and nothing is transmitted. The Uploaded readout beside the result measures this page’s own outbound network traffic, so you can confirm that rather than take it on trust.
Getting the order right
Pages follow the list from top to bottom. The arrows beside each file move it; the cross removes it.
It is worth checking before you build — reordering afterwards means starting over, and a mis-ordered scan of a contract is the kind of thing that gets noticed at the worst moment.
What about file size?
Each JPG is embedded into the PDF exactly as supplied, without re-encoding. That keeps the image quality identical to your originals, and it means the PDF is roughly the sum of the photos plus a small overhead.
Ten 3 MB photographs make a PDF of around 30 MB. If that is too large for an email attachment, compress the JPGs first and then build the PDF from the smaller files.
No watermark, no page limit, no account
Three things that free PDF tools routinely charge for, and none of them apply here — because none of them cost anything when there is no server to pay for.
Questions
- How do I combine several photos into one PDF?
- Add all of them at once, arrange the list into the order you want, and build. Each image becomes a single page, and the pages follow the list from top to bottom.
- How do I control the page order?
- Files are placed in the order shown in the list. Use the arrows beside each file to move it up or down before building, and the cross to remove one you added by accident.
- Is there a limit on how many photos I can include?
- None is imposed, because no server is doing the work and no bandwidth is being paid for. Your device's memory is the only real ceiling.
- Will the PDF have a watermark?
- No. Nothing is stamped onto the pages, and there is no paid tier that removes anything. This is the most common complaint about free PDF tools and it does not apply here.
- Are my photos uploaded?
- No. The document is assembled in this browser tab using pdf-lib. The Uploaded readout beside the result measures the page's own outbound network traffic, so a successful build reads 0 B. That matters here more than on most pages, because photographed documents are usually identity papers, receipts or contracts.
- Is the image quality reduced?
- No. Each JPG is embedded into the PDF as-is, without re-encoding, so the pages contain exactly the image data you supplied.
- How large will the PDF be?
- Roughly the combined size of your photos plus a small overhead. Because the images are embedded rather than re-compressed, a PDF of ten 3 MB photos will be around 30 MB. Compress the photos first if the total needs to be smaller.
- Can I mix JPG and PNG in the same PDF?
- Use the PNG to PDF page for PNG files. Each page here is built for one input format so the embedding path is predictable.
- Does the page size match the photo?
- Yes. Each page is sized to its image rather than forced onto a fixed paper size, so nothing is cropped and nothing is letterboxed.
- Can I use this to turn phone photos of a document into a PDF?
- Yes, and it is the most common reason people use this page. Photograph each sheet, add them all here in order, and you have a single document — without those photographs passing through anyone else's server.
