Intent & Workflow
This tool works with bookmark HTML export files, a format supported by all major browsers.
You can export bookmarks from any browser, prune them here, and download a cleaned HTML file for import elsewhere. Imported bookmarks are added alongside existing bookmarks, never overwritten.
After importing, you may export the browser's full bookmark collection again and reload it into Bookmark Prunr to prune and re-prune as often as needed.
All processing is local. Your data never leaves your computer.

- Upload: Click "Choose File" and select your exported HTML file (only .html or .htm files accepted)

Checkbox Semantics (IMPORTANT)
- Unchecked = Keep: Items that are unchecked will be kept in your export
- Checked = Remove: Items that are checked will be removed from your export
- All items load initially unchecked (all kept by default)
- Checking a folder marks the entire folder and its contents for removal
Duplicate Detection

Top-Level Wrapper Folder
Imported bookmarks are automatically wrapped in a folder named "Imported By: [Browser] [Date]". You can rename this folder after import.
Export
Click "Download Pruned HTML" to save your cleaned bookmarks. The file uses the Netscape Bookmark HTML format and can be imported into Firefox, Chrome, Edge, Safari, Opera, or Brave.
Privacy
All processing happens in your browser. Your bookmarks are never sent to any server or external service.
