Once this page is saved for offline use, you can also disconnect from the internet and keep working. Ads and anonymous visit statistics, when enabled, make their own requests, but they never receive your files or text.

Frequently asked questions

Are my files uploaded?

No. The PDFs are read and merged by JavaScript on this page using the open-source pdf-lib library. You can disconnect from the internet after the page loads and it still works.

Can I merge password-protected PDFs?

Not currently. Remove the password in the app that created the PDF first.

What is kept from the originals?

Pages, their content, links and page sizes are kept. Document-level bookmarks (outlines) and interactive form state may not be preserved.
