One PDF, in the order you dropped them
Images become pages in the order they appear in the list, so drop them in the order you want or add them in batches. Everything is combined into a single PDF — the usual reason for wanting this is a form that accepts one attachment when you have five photos of a document.
Photos are embedded as JPEG data, so a phone photo does not balloon in size on the way into the PDF.
Scans, and why they should not be uploaded
The most common use for this is turning phone photos of a document into something you can email: a signed contract, a utility bill for proof of address, a passport page for a visa application, a medical form. Those are precisely the documents that should not pass through an unknown server on the way to becoming a PDF. Here they do not.
Questions
Can I control the page order?
Pages follow the order of the list, which is the order the files were added. Remove a file with the button on its row and add it again to move it to the end.
Can I convert HEIC photos from my iPhone?
Yes. HEIC images are decoded first, in your browser, then embedded into the PDF like any other photo.
Why is my PDF large?
Because full-resolution phone photos are large. Run the images through the Compress Image tool first — capping the longest side at around 2000 pixels typically cuts the PDF to a fraction of the size with no visible difference on screen or in print.
Is the PDF built on a server?
No. It is assembled in your browser with pdf-lib, a JavaScript PDF library, and handed straight back to you as a download.
