Why add bookmarks?
Bookmarks make long PDFs easy to navigate: readers jump straight to a chapter from the side panel in Adobe Reader, browsers and phone apps.
The PDF is set to open with the bookmarks panel showing. Want a printed contents page as well? Use Add Table of Contents.
Tip: Merging chapters into one PDF? Add a bookmark at the first page of each.

Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.
Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.
