The fastest way to compress a video is to re-encode it with a more efficient codec. H.265 (HEVC) reduces file size by ~40% compared to H.264; AV1 goes even further at ~50%. Upload your video, select H.265 or AV1, and download a significantly smaller file.
Compress video files using H.265 or AV1 — cut file size by up to 60% in your browser.
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.
Use a more efficient codec. H.265 (HEVC) provides equal visual quality to H.264 at 40% smaller file size. AV1 is even better at 50% smaller. Our tool lets you pick either codec and encodes on GPU hardware for fast results.
AV1 achieves the smallest file sizes at equal quality, followed by H.265 (HEVC), then H.264. For maximum compatibility, use H.265; for minimum file size, use AV1.
Switching from H.264 to H.265 typically reduces file size by 35–50%. Switching to AV1 can reduce it by 45–60%. Results vary depending on the source content and resolution.

Not noticeably when using the right settings. Our encoder targets a high-quality CRF setting that keeps visual quality very close to the original while dramatically reducing file size.
