BookmarkLab

Live browser bookmark organizer — deduplicate, auto-cluster, clean tracking URLs, and organize your bookmarks directly in Chrome.

BookmarkLab is a bookmark manager that gives you full control over your Chrome bookmarks without the risk of accidental changes. Most people accumulate hundreds of bookmarks over years — duplicate links, broken URLs, messy folder structures, and bookmarks cluttered with tracking parameters from email newsletters and ads. BookmarkLab fixes all of this in one place. HOW IT WORKS BookmarkLab loads your bookmarks into a safe workspace. You can reorganize, delete, rename, and clean them however you like. When you are ready, you review a summary of every change and click "Sync Bookmarks" to apply them. Nothing touches your real bookmarks until you approve it. FEATURES Safe Staging Model All edits are made in memory first. A diff summary shows exactly what will be deleted, moved, or updated before anything is applied to Chrome. You stay in control at every step. One-Click Backup Before making any changes, you can download a full HTML backup of your current Chrome bookmarks. If anything goes wrong, you can restore from the backup file in seconds. Duplicate Finder BookmarkLab scans all your bookmarks and groups duplicates by URL. You can choose which copy to keep or let the auto-resolver keep the oldest version and remove the rest. Auto-Cluster Automatically sorts your bookmarks into folders by domain or topic category — folders like GitHub, YouTube, Research, Social, Finance, and Shopping — in a single click. Clean Tracking Parameters Strips marketing and analytics tags like utm_source, utm_medium, fbclid, and gclid from your saved URLs. This makes bookmarks cleaner, easier to share, and prevents duplicate detection from treating the same URL as different ones. Link Health Check Checks every bookmarked URL to see if it is still reachable. Broken and dead links are flagged so you can decide whether to delete or update them. Search and Filter Search across all bookmarks by title, URL, domain, or tag. Smart views let you instantly filter to duplicates, uncategorized bookmarks, links with tracking parameters, or broken links. Drag and Drop Organizer Move bookmarks and folders around using a drag-and-drop tree view. Rename items, change URLs, and reorganize your folder structure visually. PRIVACY BookmarkLab reads your bookmarks only within your browser. No data is sent to any server, no account is required, and no analytics are collected. Everything runs locally on your device. COMPATIBILITY Works in Chrome, Edge, Brave, and any Chromium-based browser that supports the chrome.bookmarks API.
