Merge PDF Files
Combine several PDFs into one, reorder them, without uploading anything.
About this merge pdf files
Almost every free PDF merger works the same way: you upload your documents to a server, they get combined there, and you download the result. Which means your contracts, bank statements, medical letters and signed forms have been sitting on someone else's machine.
This one does it in the browser. The files are read into memory on your own device, merged there, and handed straight back to you. Nothing is transmitted, which you can verify by watching your network tab or by disconnecting from the internet before you merge.
How to use it
- Drop your PDFs onto the box, or click to choose them.
- Drag the files into the order you want them combined.
- Remove any you changed your mind about.
- Merge, then download the single combined file.
Merge PDF Files — FAQ
Are my PDFs uploaded anywhere?
No. They are read and merged entirely in your browser. Disconnect from the internet after the page loads and it still works.
Is there a file size or page limit?
Only your device's memory. Merging a few hundred pages is comfortable; very large scanned documents may be slow on a phone.
Does merging reduce quality?
No. Pages are copied across intact, so text stays selectable and images keep their original resolution.
Can it merge password-protected PDFs?
No. Encrypted files have to be unlocked first, which requires the password and is outside what this tool does.
Does it keep bookmarks and form fields?
Page content, text and images are preserved. Interactive form fields and bookmarks may not survive the copy — check the result if your document relies on them.
