What does Merge PDF do?

Select multiple PDF files, drag them into the order you want, and download a single merged document. Bookmarks and page sizes from each source are preserved, and text stays selectable because pages are copied rather than rasterised.

Frequently Asked Questions

Is there a limit on how many PDFs I can merge?

No server limit, because nothing is uploaded. The practical limit is your device memory — dozens of ordinary documents merge comfortably; hundreds of large scans may be slow on a phone.

Will the merged PDF still be searchable?

Yes. Pages are copied at the object level, so fonts, text layers and vector graphics come across intact. Scanned pages that were images before remain images.

What happens if the PDFs have different page sizes?

Each page keeps its own size and orientation. Nothing is scaled or cropped, so an A4 report merged with a landscape spreadsheet keeps both exactly as they were.

Can I merge a password-protected PDF?

Not directly. Remove the password first with the unlock tool — which needs the password you already have — then merge the unlocked copy.

100% Data Privacy

Your PDF is opened and rewritten by a JavaScript PDF engine running inside this page. The file never leaves your device, which matters for contracts, statements, medical records and ID scans.
