Video validator for Reddit
Pick a video file. Koldflux reads metadata locally and reports PASS / WARNING / FAIL / UNKNOWN against Reddit. 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 Reddit accept this extension)
- File size vs. Reddit max
- Aspect ratio vs. Reddit recommended
