Frequently asked questions
Is there a limit on how many files I can merge?
No hard limit — practical limits depend on your device's memory, since merging happens locally in the browser.
Does merging reduce quality?
No — pages are combined as-is; nothing is re-rendered or recompressed.
Can I merge a password-protected PDF?
You need to open it with the correct password in a PDF reader first. We don't offer a password-removal tool.
Do my files get uploaded anywhere?
No — merging runs entirely in your browser via WebAssembly; nothing is sent to a server.
