FAQ
Good to know
No. The files are read by your browser and merged in memory with the open-source pdf-lib library. They never leave your device.
Each file can be up to 50 MB. Very large documents are limited only by your device's memory.
Page content is copied exactly. Document-level extras such as bookmarks and fillable form logic may not carry over.
