✳ VALIDATOR · INSTAGRAM FEED
Subtitle validator for Instagram Feed
Pick a subtitle file. Koldflux reads metadata locally and reports PASS / WARNING / FAIL / UNKNOWN against Instagram Feed. Nothing uploaded.
Extension and MIME type are labels, not proof of the container. Dimensions and duration come from this browser's media reader. Files and measurements are not sent anywhere.
What this checks
- Container compatibility (does Instagram Feed accept this extension)
- File size vs. Instagram Feed max
- Aspect ratio vs. Instagram Feed recommended
- Caption character and duration limits
Convert a failing file in one click: /tools/convert
