How JPG to AVIF Conversion Works

JPEG Image (JPG) uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. AV1 Image File Format (AVIF) applies AV1 intra-frame compression delivering 50% smaller files than JPEG at equivalent quality, with wide colour gamut support. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. The result is a standard AVIF file readable by any compatible application. 1converter handles JPG-to-AVIF conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.

Frequently Asked Questions

Everything you need to know about converting JPG to AVIF

AVIF can look better at the same size because its modern codec compresses more efficiently, but it can’t recover detail lost by prior JPG compression. If you used high-quality source JPGs, AVIF will typically preserve details very well.
AVIF frequently produces smaller files than JPG for the same visual quality, especially for photos, gradients, and complex textures. Exact savings depend on the content and chosen AVIF quality settings.
AVIF is widely supported in modern browsers, but not all older software supports it. For maximum compatibility, you may need a fallback to JPG in environments that lack AVIF decoding.
Yes—unlike JPG, which has no alpha channel, AVIF can include transparency (alpha) when the source or conversion settings provide it. If your JPG is opaque, the result will typically remain opaque.
