Useful answers

Before you combine

Does it need an account or payment?

No. This version requires neither.

Which PDFs can I combine?

Ordinary, static and unlocked PDFs, including scanned pages. Password-protected PDFs and files with forms, signatures, annotations, links, bookmarks, attachments or accessibility tags are rejected rather than silently changed.

How many PDF files can I merge?

For now, choose up to 20 files, 100 pages and 25 MB in total. These are protective limits and have not yet been established through phone memory testing.

Can I combine PDFs on a phone?

You can use the browser tool on a phone. Save PDF remains available; Share PDF appears when the device and browser report that file sharing is supported.
