AVI files are often huge because they use older, less efficient codecs. Converting to H.265 HEVC can reduce an AVI file to 10–20% of its original size while keeping the same visual quality. Perfect for freeing up hard drive space.
Turn bloated AVI files into compact H.265 HEVC MP4 without losing quality.
Upload your AVI 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. 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.
H.265 (HEVC) is a modern video codec with roughly 40% better compression than H.264 at equal visual quality. Converting to H.265 (HEVC) 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.
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.
