Merge PDFs
Drop several PDF files, arrange them in order, then merge them into one. Everything runs in your browser — your files never leave your device.
About merging PDFs
The tool appends pages from each PDF in the order you drop or arrange them — first file first, last file last. It copies pages as-is: fonts, images, and vector graphics are preserved without re-encoding. The result is a single PDF you can download and share.
Is it private?
Yes. The converter is WebAssembly and browser APIs running on your own machine. Nothing is uploaded, stored, or seen by us — there is no server to send files to.
Frequently asked questions
- In what order are the PDFs combined?
- Pages are appended in the order you drop or arrange the files, so the first file comes first and the last file comes last. You can rearrange the files before merging to control the final sequence.
- Are my files uploaded to a server?
- No. The merge runs on your device using WebAssembly and browser APIs. Your files are never sent anywhere, and the tool keeps working even if you go offline after the page loads.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop your files, merge them, and download the result.
- Is the content of my PDFs changed during merging?
- No. Pages are copied as-is, so fonts, images, and vector graphics are preserved without re-encoding. The result is a single PDF that keeps the original page content intact.
