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, which usually yields smaller files than JPEG at similar 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.

When to convert
What the AVIF file is good for and why people convert to it.
- Often reduces file size substantially versus JPG using AV1/AVIF encoding
- Better compression at similar perceived quality for photos and gradients
- Shrink a photo gallery’s images for faster page loads and bandwidth savings
- Convert screenshots or product shots to AVIF for responsive web delivery
Where your file goes
- It travels to our server over an encrypted HTTPS connection and is converted there.
- The AVIF file comes back as a private link. It stops working after 24 hours on Free and 7 days on paid plans, and then the files are deleted.
- Want the file to stay on your device? Private Mode converts images right in the browser. Open Private Mode
