Frequently asked questions
How do I export my bookmarks to an HTML file?
Chrome, Edge, and Brave: Bookmark manager > three-dot menu > Export bookmarks. Firefox: Manage bookmarks > Import and Backup > Export Bookmarks to HTML. Safari: File > Export > Bookmarks. Then drop the exported file above.
What counts as a duplicate bookmark?
Two bookmarks pointing at the same page - ignoring #fragments, utm_* and fbclid tracking parameters, and trailing slashes. The first copy is kept where it lives; later copies are removed, and the report shows exactly which ones and where.
Does this delete anything from my browser?
No. It only cleans the exported file and hands you back a new one. To apply the cleanup, delete the old bookmarks in your browser first, then import the cleaned file - otherwise you'd re-duplicate everything.
What happens to empty folders?
Folders with nothing left in them (including folders that only contained duplicates) are removed, and the report lists each one so you can double-check before importing.
Are my bookmarks uploaded anywhere?
No. The file is parsed and cleaned entirely in your browser - it never touches a server.
