What it does

• Import HTML, JSON or CSV bookmark files, with a full preview first — counts, folders, depth, duplicates and warnings before anything is written.
• Choose how: into a new dated folder (the safe default), merged into your existing folders, or replacing everything. Replace saves a JSON safety backup first and deletes nothing until that backup is proven.
• Export everything, or just the folders you pick, to HTML (Chrome, Edge, Brave, Firefox, Safari, Vivaldi, Opera), JSON, CSV or Markdown.
• Edit the tree: search, rename, drag & drop, create folders, delete, and find duplicate links — every action reachable from the keyboard.

Privacy

This is the whole point of the project, so it is worth being precise.

• No network access at all. Not analytics, not telemetry, not update pings. There is no server. A grep gate (npm run guard) fails the build if anyone adds fetch, XMLHttpRequest, WebSocket, EventSource or sendBeacon.
• Exactly two permissions: bookmarks and storage. No host permissions, no content scripts, no background worker. Two gates enforce it: a unit test over wxt.config.ts, and npm run check:manifest, which CI runs against the built manifest.json — because a build can add what the config never asked for.
• Zero runtime dependencies. Nothing third-party ships in the extension.
• Settings use chrome.storage.local, never storage.sync, so even your preferences stay off any vendor cloud.

Full policy: legal/PRIVACY.md.

Honest limitations

• Favicons cannot be imported — the bookmarks API has no favicon field.
• Imported bookmarks get today's date. Chrome does not let an extension set a bookmark's original creation date. Your exported files keep the real ones.
• CSV is a flattened view: empty folders and "which folder is the toolbar" are not preserved. Use HTML or JSON for a faithful backup.
• Markdown is share-only — BookmarkMagic cannot read it back.

Install

From the Chrome Web Store: here

From source:

npm ci && npm run build

Then load .output/chrome-mv3/ at chrome://extensions with Developer mode on.

Development

npm run dev

npm run verify is the gate everything else answers to — lint, type-check, knip, the grep gate and the test suite, in that order. It must be green before every commit.

The docs/ directory is the binding specification, not notes: where code and docs disagree, the docs win. Start with CLAUDE.md, then docs/00–docs/02.

Contributing

Bug reports and translation fixes are welcome via issues. A bug report about parsing is far more useful with a sanitized sample of the file that broke.

Security issues: please follow SECURITY.md rather than opening a public issue.

Support development

Entirely optional — BookmarkMagic is free software either way.
