Why this tool is different
Photographing documents is easy; turning eight photos into one PDF that an office will accept is where it falls apart. Add the images, put them in the right order, pick a page size, and you get a single PDF — built on your device, so scans of your ID or bank statements are not travelling to a server first.
How it works
- 1
Add your images. Photos of documents work well.
- 2
Reorder them until the sequence is right.
- 3
Choose A4, Letter or fit-to-image, plus orientation and margin.
- 4
Build the PDF and download it.
What to watch out for
Original quality is preserved where possible
When no resizing is needed, the original JPEG data is embedded directly rather than decoded and re-encoded. That keeps quality identical and the process fast.
Page size choices
A4 and Letter fit each image into a standard page with margins, which is what offices expect. Fit-to-image makes each page exactly the size of its photo, which suits screenshots and receipts.
If the result is too large
A PDF of high-resolution photos gets big quickly. If an upload limit is the problem, use the target-size version of this tool instead.
Frequently asked questions
Can I choose the page order?
Yes. Reorder pages before building, with buttons that work on touch as well as drag-and-drop on desktop.
How many images can I combine?
There is no fixed limit, but very large batches use a lot of memory on a phone. We warn you before starting a job that looks too heavy for the device.
Does it reduce my image quality?
Not unless it has to. Where no resizing is required, the original JPEG bytes are embedded unchanged.
Are my files uploaded to a server?
No. The conversion runs in JavaScript and WebAssembly inside your own browser. Open your devtools, switch to the Network tab and run a conversion — there is no upload request to see. Closing the tab clears the working session.
