✳ VALIDATOR · LINKEDIN
Subtitle validator for LinkedIn
Pick a subtitle file. Koldflux reads metadata locally and reports PASS / WARNING / FAIL / UNKNOWN against LinkedIn. 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 LinkedIn accept this extension)
- File size vs. LinkedIn max
- Aspect ratio vs. LinkedIn recommended
- Caption character and duration limits
Convert a failing file in one click: /tools/convert
