What is JPEG?

Joint Photographic Experts Group (JPEG) — The most widely used lossy image format, ideal for photographs and complex images with millions of colors. Offers adjustable compression to balance quality and file size.

  • Format type: Lossy
  • File extension: .jpeg

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

Why Convert JPEG to AVIF?

While converting from a lossy format (JPEG) to a lossless format (AVIF) won't recover lost image data, it provides a high-quality container for further editing. The AVIF file will preserve every pixel exactly as decoded from your JPEG source without additional quality loss.
