About this conversion
What happens
After consent, the WebM uploads directly to temporary Hetzner storage and runs in an offline converter plus separate validator.
Limits
250 MiB input. 15 minutes, up to 3840×2160, and 500 MiB output.
Things to know
Keep resolution for fidelity or cap it at 1080p/720p. Balanced quality is the default for normal sharing and playback. Non-WebM containers, unlisted codecs or streams, excessive duration/resolution, timeout, or invalid output fail closed.
