Questions

Yes. It is free with no sign-up and no watermark. The free plan covers up to 50 tasks a day; Pro removes every limit.
Do you upload my files?
No. The tool runs inside your browser using WebAssembly. Your file never leaves your device, and it still works with Wi-Fi turned off.
Does it work on my phone?
Yes. It works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows, Mac and Linux.
My PDF has no bookmarks. What can I do?
Use Split PDF with page ranges, or Split PDF by text if each part starts with the same words, like "Chapter".
What happens to the pages before the first bookmark?
The cover and contents pages before the first bookmark become their own part, called front matter, so nothing is lost.
