About this tool
Organize bookmarks with folders, categories, tags, favorites, drag-and-drop, search, filters, bulk actions, and import/export.
The Bookmark Organization Assistant imports a browser's Netscape-format bookmarks HTML export or a JSON backup and turns it into a filed library with folders, tags, favourites, drag-and-drop sorting and bulk actions, all held in your browser. It is for people whose exported bookmarks file has thousands of unsorted links and who need to triage them in batches rather than one at a time. Counters at the top track total bookmarks, favourites, folders and distinct tags as you work, and you can sort the list by date added, title A–Z, or how often you have opened each link.
Open Bookmark Organization Assistant on AltFTool — it loads instantly in your browser.
Press Add bookmark in the toolbar and fill in Title, URL, Description, Folder and Tags (comma separated). URL is required, and anything that is not an http or https address is rejected with Please enter a valid http(s) URL. Tick Mark as favorite to star it, then press Add bookmark again to save.
Press Add folder in the Library header of the sidebar, name it in the New folder dialog and press Create, then drag a bookmark card onto a folder row to file it there. Deleting a folder moves its bookmarks back to General.
Search by title, URL, tag, or description, sort by Name (A-Z), Newest first or Most used, and press Select to open the bulk bar with Favorite, Unfavorite, Move to, Add tag and Delete. Export saves bookmarks.json, and Import accepts a .json or Netscape .html file, then asks whether to Merge or Replace all.
Parses Netscape bookmarks HTML — the file every major browser exports — as well as JSON, then asks whether to merge or replace before touching your library.
Selection mode lets you favourite, move to a folder, apply a tag or delete many bookmarks in one action, with Select All scoped to the current filter.
Opening a bookmark increments its use count, so the 'most used' sort reflects what you actually return to rather than what you saved most recently.
Either a bookmarks HTML file in the Netscape format that Chrome, Firefox, Edge and Safari all export, or a JSON file previously exported here. After parsing, you are shown the bookmark count and asked to merge into your current library or replace it entirely.
They are moved to the General folder, not deleted. Deleting a folder is confirmed first and cannot be undone, but the links themselves survive the move.
Yes, for one bookmark at a time — deleting a single card shows a toast with an Undo action that restores it. Bulk deletion of a selected set has no undo, so export a JSON backup before large clear-outs.
A bookmark lives in exactly one folder but can carry any number of tags, so folders give you a single filing location and tags give you cross-cutting labels. The sidebar lists both, and the stats row counts distinct tags across your whole library.
