Small, free tools that run in your browser. Nothing you add leaves your device.

- [Free safe zone checker for Reels, TikTok and Shorts](https://viditor.app/tools/safe-zone-checker): Drop a frame or video and see what Reels, TikTok, Shorts, the Instagram grid and YouTube cover. Free, and your file never leaves the browser.
- [Script to video length calculator](https://viditor.app/tools/video-length-calculator): Paste a script to see how long it runs spoken at 120, 150 or 180 words per minute, and whether it fits Reels, Shorts, TikTok and YouTube limits.
- [YouTube chapters formatter](https://viditor.app/tools/youtube-chapters-formatter): Paste your timestamps in any order or format and get YouTube chapter lines checked against the rules: 00:00 first, at least 3, each 10 seconds or longer.
