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.
You’ve tried our free online encoder — but if you need larger files, bulk jobs, or enterprise-grade throughput, Convertrilo has you covered. GPU-powered encoding, predictable pricing, and instant scaling when you need it most.
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. No sign-up is required for the free tool. You get up to 720p output and files up to 200 MB. Create a free account to unlock 1080p, larger files, and 1,000 free encoding minutes.
Encoding speed depends on file length and selected resolution. Most short clips (under 5 minutes) finish in under 60 seconds on our GPU infrastructure.
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.
