Frequently asked questions
Are my PDFs uploaded to a server?
No — the files are read and combined entirely in your browser using a local PDF library. Nothing leaves your device.
Does this work on password-protected PDFs?
No — encrypted or password-protected PDFs can't be read locally without the password, so merging will fail on those files. Remove protection first if needed.
