What is AVIF?

AV1 Image File Format (AVIF) — A next-generation format based on the AV1 video codec. Delivers superior compression — up to 50% smaller than JPEG — with support for HDR, wide color gamut, and transparency.

  • Format type: Lossy / Lossless
  • File extension: .avif

What is WEBP?

WebP Image Format (WEBP) — A modern format developed by Google offering both lossy and lossless compression. Produces files 25–35% smaller than JPEG at equivalent quality, with transparency support.

  • Format type: Lossy / Lossless
  • File extension: .webp

Why Convert AVIF to WEBP?

Both AVIF and WEBP are lossless formats, so converting between them preserves full image quality. This conversion is useful for compatibility — WEBP may be better supported by your software, platform, or workflow.
