Features
Nothing is uploaded
The PDFs are read and joined by your browser using the pdf-lib library. No copy is sent to a server, which matters for bank statements, ID scans and legal documents.
Keeps every page as it was
Pages are copied exactly, so text stays selectable, links keep working and the print quality does not change. The tool does not re-compress or rasterise your pages.
Any number of files
Merge two files or twenty. The only real limit is your device's memory; most phones handle a few hundred pages comfortably.
No watermark, no sign-up
The merged file is clean, with no logo stamped on the pages and no account needed.
When to use it
Job and university applications
Portals often ask for a single PDF. Merge your CV, degree, transcript and certificates into one file in the order the form lists them.
Monthly paperwork
Join invoices, receipts or salary slips for one month into a single file for your accountant or your own records.
Scanned pages
If your scanner saved each page as a separate PDF, merge them back into one document before you send it.
Frequently asked questions
Is it safe to merge confidential PDFs here?
Yes. The files are processed on your own device and never uploaded. You can even disconnect from the internet after the page loads and the tool still works.
Can I merge password-protected PDFs?
Not directly. If a PDF needs a password to open, remove the protection first in your PDF reader, then add it here. The tool tells you which file is protected.
Will the file size get bigger?
The merged file is roughly the size of all the files added together. If you need a smaller file for an upload limit, compress it after merging.
Does merging change the quality?
No. Pages are copied as they are, without being converted to images, so text, vector graphics and images keep their original quality.
Can I change the page order inside a file?
This tool orders whole files. To reorder or remove single pages, split the PDF first or use a page organiser, then merge the parts.
