HEVC (H.265) encodes video about 40% more efficiently than H.264. If you have a large H.264 library, converting to HEVC is one of the fastest ways to reclaim storage while keeping the same visual quality. Great for 4K footage, long recordings, and archiving.
Re-encode H.264 to HEVC — shrink file size by ~40% with no 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 H265 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.
H.265 (HEVC) is a modern video codec with roughly 40% better compression than H.264 at equal visual quality. Converting to HEVC (H.265) is ideal for 4K video, HDR content, and reducing storage requirements.
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.
