JPG has been the standard photo format for decades, but AVIF delivers the same visual quality in files that are up to 50% smaller. Built on the AV1 video codec, AVIF represents the biggest leap in image compression since WebP. ConvertFile processes your conversion on our secure server using Sharp for optimal results.

Why Convert JPG to AVIF?

AVIF produces files that are up to 50% smaller than JPG at the same visual quality, according to independent compression studies. For a website serving hundreds of images, that translates to dramatically faster page loads and lower bandwidth costs.

Unlike JPG, AVIF also supports transparency, HDR, and wide color gamuts. If you shoot HDR photos or work with 10-bit color, AVIF preserves that data while JPG cannot. All major browsers now support AVIF: Chrome 85+, Firefox 93+, and Safari 16+.

What is JPG?

JPG (JPEG) is the most widely used image format on the web. It uses lossy compression to produce small files, discarding visual information that the human eye is unlikely to notice. At 85-90% quality, most people cannot tell the difference between a JPG and the original. JPG does not support transparency, and re-saving a JPG repeatedly causes gradual quality loss, a process called generation loss.

What is AVIF?

AVIF (AV1 Image File Format) was developed by the Alliance for Open Media in 2019. It is based on the AV1 video codec and delivers up to 50% smaller files than JPEG at equivalent visual quality. AVIF supports lossy and lossless compression, transparency, HDR, wide color gamuts, and animation. Browser support includes Chrome 85+, Firefox 93+, and Safari 16+. Encoding is slower than JPEG or WebP, but the file size savings are substantial.

Secure Server-Side Processing

Your JPG files are processed on our secure server using Sharp, a high-performance image processing library, and temporarily stored. Files are automatically deleted within 1 hour. This server-side approach enables AVIF encoding that would be too slow or unsupported in most browsers.

Frequently Asked Questions

How much smaller is AVIF compared to JPG?

AVIF files are up to 50% smaller than JPG at the same visual quality. The exact savings depend on image content, but photographs typically see 30-50% reductions.

Is there visible quality loss?

At equivalent quality settings, AVIF and JPG are visually indistinguishable. AVIF actually handles fine details and gradients better than JPG, producing fewer compression artifacts at low file sizes.

Do all browsers support AVIF?

AVIF is supported by Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. This covers over 92% of global browser traffic. For maximum compatibility, keep a JPG fallback for older browsers.

Why is the conversion server-based?

AVIF encoding requires significant processing power and is not supported by browser Canvas APIs. Server-side conversion with Sharp delivers faster results and better quality than any browser-based approach.

Are my files secure during conversion?

Yes. Files are processed on our secure server and temporarily stored. They are automatically deleted within 1 hour of processing.

Can AVIF replace JPG on my website?

For modern browsers, yes. Use the HTML picture element to serve AVIF to supported browsers and JPG as a fallback. This gives you the best of both worlds: smaller files for most visitors and universal compatibility.

Does AVIF support animation?

Yes. AVIF supports animated sequences, similar to GIF or animated WebP, but with much better compression. This converter handles static images only.

Will the image dimensions change?

No. The output AVIF has the exact same width and height as the input JPG. Only the file format and compression method change.
