FAQ
Is this PDF merge tool free to use?
Yes, this tool is completely free to use with no limits on how often you can use it.
Do my files get uploaded to a server?
No. All merging happens entirely in your browser using JavaScript. Your PDF files are never uploaded anywhere — they never leave your device.
Is there a limit on file size or number of files?
There's no hard limit enforced by this tool, but since everything runs in your browser rather than on a server, very large files or a large number of files may take longer to process.
