PDF files, merged in the order listed
Stitch two or more PDFs into one continuous document. Every page of the first file is followed by every page of the next, in the order you set, so a stack of separate reports, invoices, or scans becomes a single file. The merge runs in your browser with pdf-lib — nothing is uploaded and no watermark is added.
Order is decided before you merge, not after
Files are joined end to end in exactly the sequence you arrange them, and the pages inside each file keep their own order. There's no re-sorting step afterwards, so set the order first. If one file needs to be broken up mid-document, split it and add the pieces as separate items.
What copies across — and what doesn't
- Page content, text, images, and links transfer faithfully into the combined file.
- Document-level extras — outline bookmarks and interactive form fields — may not survive, because pages are copied into a fresh document rather than the original containers being fused.
- Encrypted files can't be merged while locked; remove the password first.
How to use it
- Add the PDF files you want to join — several at once or one by one.
- Drag them into the order they should appear in the final document.
- Merge, then download the single combined PDF.
Frequently asked questions
- Is there a limit on the number or size of files?
- No fixed limit, but everything is held in your browser's memory, so very large or very many files at once can slow down or run out of memory on a modest device. Merge in smaller batches if you hit a wall.
- Are my PDFs uploaded to a server?
- No. The combining is done in your browser with pdf-lib, so every file stays on your device — safe for contracts, statements, and anything private.
