Hey Product Hunt! 👋 We all occasionally need to batch rename files — organizing photos, cleaning up TV show names, or standardizing document naming. But installing a dedicated app or paying for software just for occasional use feels like overkill. That's why I built a browser-based tool that's free, requires no installation, and handles these light-use scenarios perfectly. Rename.Tools is a browser-based batch renamer that: 🔒 **Privacy-first** — Files never leave your device. Uses File System Access API for direct local operations. ⛓️ **Rule Chains** — Combine multiple rules (find/replace → regex → add sequence → convert case). Drag to reorder. 👁️ **Live Preview** — See changes instantly with conflict detection. Auto-fix suggests solutions. 📷 **Smart Metadata** — Extract EXIF dates from photos, audio tags from music files. Use them in rename templates. 📺 **TV Show Scraper** — Match video files with TMDb episode data. Auto-rename to "Show - S01E01 - Episode Title.mkv". ↩️ **Full Undo** — Made a mistake? One click to revert. Export undo scripts for backup. It's open source (AGPL-3.0), no accounts, no tracking, no file uploads. Works in Chrome/Edge/Brave/Arc. **Try it:** https://rename.tools **GitHub:** https://github.com/chenz24/renam... I'd love to hear what you think! What's your biggest file naming pain point? Happy to add features based on your feedback. 🙏
