Frequently asked questions
What if my PDF has no bookmarks?
Use Split by pages or Split by text instead, which work on any PDF.
Are the files named after the chapters?
Yes. Each file name includes the title of the bookmark it starts at.
Are my files uploaded to a server?
No. This tool runs entirely in your web browser, so your files never leave your device. That makes it safe for contracts, invoices and other private documents.
