Frequently asked questions
Is the oMyPDF bookmark tool free?
Yes. Adding and editing PDF bookmarks is 100% free with no watermark and no sign-up required.
What are PDF bookmarks?
Bookmarks (the document outline) form a clickable table of contents shown in a PDF viewer's sidebar. Each one jumps to a specific page.
Can I nest bookmarks?
Yes. Use Indent to place an entry under the one above it, building chapters with sections and sub-sections.
Will it keep my existing bookmarks?
When you upload a PDF, its current outline is loaded automatically so you can edit, reorder or extend it. Saving replaces the outline with your final list.
Are my files safe?
PDFs under 15 MB are processed entirely in your browser and never uploaded. Larger files are sent over an encrypted connection, processed immediately, and deleted right after.
