Tools for Shorts, Reels and TikTok
One vertical edit, three apps.
Free tools for creators who post the same vertical video to YouTube Shorts, Instagram Reels and TikTok. Each app covers a different part of the frame and has its own limits; these tools check your edit against all three at once. Everything runs in your browser: no sign-up, nothing uploaded, nothing stored.
Colour tag checker
- YouTube
- Shorts

Why an export looks washed out: its colour tags in the container and the bitstream, how Chrome, Safari and QuickTime show it (measured), and the setting that fixes it.

- YouTube
- Shorts
- Reels
- TikTok
- Podcasts
- Audiobooks

Open →TikTok and Instagram publish less than YouTube, so more of the figures here are measured than cited. Each tool says which is which: published figures name their source and the date they were checked, and measured ones say how they were measured.
