Merge, then compress

Frequently asked questions
Will merging reduce quality?
No. Pages are copied without re-encoding.
Can I merge password-protected PDFs?
Not directly — remove the password first in a PDF reader you're authorised to use.
Are my PDFs uploaded to a server?
No. Compression runs entirely inside your browser using JavaScript and WebAssembly-grade libraries. Your file never leaves your device, so confidential documents stay private. You can even disconnect from the internet after the page loads and it keeps working.
