How it works
Merge PDF runs entirely in your browser using your device's own processing power. When you choose a file, nothing is sent anywhere — the operation happens locally, and the result downloads straight to your device when it's done.
Common questions
Is my file uploaded anywhere?
No. This tool processes your file directly in your browser. It is never sent to a server, stored, or seen by anyone.
Is there a file size or daily limit?
No daily limit. Very large files (roughly 100MB+) may be slow since everything runs on your own device's memory rather than a server.
Do I need to create an account?
No. Every tool on this site is free and requires no sign-up.
