AV1 offers dramatically better compression than H.264. Converting an existing H.264 video to AV1 can cut file size in half while maintaining the same visual quality — ideal for archiving, web delivery, or YouTube uploads where AV1 streams at lower bitrates.
Re-encode H.264 MP4 to AV1 — shrink file size by up to 50% without visible quality loss.
Upload your H.264 file using the tool above, make sure the output codec is set to AV1 and the container to MP4, then click Convert. No software installation required — encoding runs on our GPU servers.
Yes. The public tool works without sign-up for capped preview jobs up to 720p and 200 MB. Create a free account to unlock up to 8K/120fps, larger files, starter credits, and production encoding workflows.
Encoding speed depends on file length, queue depth, codec, and selected resolution. Short public jobs usually finish quickly, while account jobs give you higher limits and production controls.
AV1 is a modern video codec with significantly better compression than H.264 and H.265, reducing file size by 30–50% at the same quality. Converting to AV1 is ideal for web streaming, archiving, and platforms like YouTube that support AV1 delivery.
Yes. By default the tool re-encodes audio to AAC at 192 kbps for MP4/MKV/MOV, or Opus at 128 kbps for WebM. You can also choose to copy the original audio stream unchanged or strip it entirely using the Audio selector.
The public encoder is useful for quick previews. For larger files, up to 8K/120fps output, bulk jobs, API access, storage outputs, and webhooks, create an account and run production workflows with predictable NEU estimates.
