Bookmark Icon Customizer

About

Customize your bookmark icons with emojis, 14,000+ Material Design Icons, or your own images.

Give your bookmarks a face. Replace any bookmark's favicon with an emoji, a Material Design Icon (14,000+ glyphs), or your own image — so a glance at your bookmark bar tells you exactly what's what.

WHAT YOU CAN DO
━━━━━━━━━━━━━━━━━━━━━

• Pick any emoji — rendered at 128×128 so it stays crisp on high-DPI displays.
• Search the full Material Design Icons library (14,000+ glyphs) right in the popup.
• Upload your own PNG, JPG, or ICO — sizing and caching are handled for you.
• Works on plain URLs, javascript: bookmarklets, AND webhook bookmarks.
• Every change is reversible — untick the customization and the bookmark is restored.

BOOKMARKLETS, WITH ICONS
━━━━━━━━━━━━━━━━━━━━━

Chrome normally shows bookmarklets with a generic gear. This extension rewrites them into proper icon-carrying launchers while preserving the original JavaScript verbatim inside the URL — so if you ever uninstall, they self-heal back to their original javascript: form.

━━━━━━━━━━━━━━━━━━━━━
WEBHOOK BOOKMARKS
━━━━━━━━━━━━━━━━━━━━━

Tick one box and a bookmark becomes a silent button: clicking it fires the URL in the background without opening a tab. Perfect for Home Assistant, n8n, Zapier, or any "click = do a thing" trigger you want on your bookmark bar.

HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━

Chrome's favicon cache is keyed by URL and has no public write API, so this extension does the plumbing:

Plain URLs — the target is opened once in a small focused-off popup so Chrome caches your chosen favicon for that URL.
Bookmarklets — rewritten to an extension launcher page that carries the favicon; the original JS is preserved in the URL and self-heals on reinstall.
Webhooks — rewritten to a data:text/html URL with the favicon inlined, fired silently on click.

PRIVACY
━━━━━━━━━━━━━━━━━━━━━

Local-only storage. No tracking, no analytics, no accounts. Your bookmarks never leave your machine. Host permissions are optional and only requested for the specific domains you customize.
