Video Formats in 2026: MP4, WebM, AV1, and Which to Use

A comprehensive comparison of modern video formats including MP4, WebM, MKV, and the next-gen AV1 codec. Learn which format is best for your use case.

The video format landscape in 2026 offers more choices than ever. MP4 with H.264 remains the universal baseline — it plays everywhere from old smartphones to smart TVs. H.265 (HEVC) offers 50% better compression but licensing costs limit its adoption in open-source tools.

WebM with VP9 is the web's preferred format: royalty-free, natively supported by all major browsers, and used by platforms like YouTube. VP9 achieves compression similar to H.265 without the licensing headaches.

AV1 is the next generation: developed by the Alliance for Open Media (Google, Mozilla, Netflix, Amazon), it offers 30% better compression than VP9. Browser support is now universal, and hardware decoding is standard in devices shipped since 2023.

For social media uploads, MP4 (H.264) is the safe choice — every platform accepts it. For web embedding, WebM offers smaller files. For archival and quality-first workflows, MKV with lossless codecs preserves every frame perfectly.

ConvertCraft's Video Converter handles all these formats in your browser. Convert between MP4, WebM, MKV, AVI, and MOV with configurable codec settings. All processing happens locally — your videos never leave your device.
