H.265 (HEVC) is the successor to H.264, offering roughly 40% better compression at equal visual quality. It's widely supported on Apple devices, modern smart TVs, and 4K Blu-ray. Convertrilo uses GPU hardware acceleration for HEVC encoding without any software installation.
Encode video to H.265 HEVC online — 40% smaller files than H.264, hardware acceleration.
H.265, also called HEVC (High Efficiency Video Coding), is a video codec that achieves about 40% better compression than H.264 at the same visual quality. It is the standard for 4K Ultra HD video and HDR content.
Yes. The public HEVC tool works without an account for capped previews up to 720p and 200 MB. Create a free account for up to 8K/120fps, higher limits, starter credits, and production encoding workflows.
H.265 uses more advanced prediction and motion compensation algorithms to reduce file size by approximately 40% compared to H.264 at equal quality. The trade-off is that H.265 encoding is slower and slightly less compatible with older devices.
Yes. All Apple devices from 2017 onwards (iPhone 7+, iPad Pro 2017+, Mac with A9/A10 or Intel Kaby Lake+) support H.265 hardware decode. macOS and iOS natively handle HEVC playback.
H.265 has broader hardware compatibility (especially on Apple and older devices) and faster hardware encoding. AV1 achieves better compression but support is still catching up. For maximum compatibility, use H.265; for minimum file size, use AV1.
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.
