Free Avif Image Compressor — No Limits, No Upload
Optimize AVIF images — the most efficient image format available — for maximum web performance. imgavio processes everything locally in your browser using WebAssembly technology — your images never leave your device at any point. This gives you the privacy of desktop software with the convenience of an online tool.
Unlike tools such as iLoveIMG, TinyPNG, or remove.bg that send your files to their servers, imgavio's AVIF image compressor works entirely on your device. This means: no waiting for uploads, no privacy risks, no file size restrictions, and no slowdowns from server queues.

AVIF: The Most Advanced Image Format
AVIF is built on the AV1 video codec, which represents decades of video compression research from the Alliance for Open Media (Google, Apple, Microsoft, Mozilla, Netflix, and others). This makes AVIF extraordinarily efficient at image compression — typically achieving 50% smaller files than JPEG and 20% smaller than WebP at the same perceptual quality.
Serving AVIF with Fallbacks
Since AVIF isn't supported by all browsers, best practice is to serve AVIF to compatible browsers with a WebP or JPEG fallback. Use the HTML <picture> element to provide multiple formats. The browser automatically uses the first format it supports.
Frequently Asked Questions
-
What is AVIF?AVIF (AV1 Image File Format) is the newest major image format, derived from the AV1 video codec. It delivers up to 50% smaller files than JPEG at equivalent visual quality.
-
Is AVIF supported by all browsers?AVIF is supported by Chrome (85+), Firefox (93+), Edge (121+), Safari (iOS 16+, macOS Ventura+). Global support is approximately 90-93%. For maximum compatibility, provide a JPEG/WebP fallback.
-
Is AVIF better than WebP?Yes, in most cases. AVIF typically achieves 20-30% smaller files than WebP at the same quality. However WebP has broader browser support.
-
Should I use AVIF or WebP?Use AVIF for modern websites where you can serve different formats to different browsers. Use WebP as the fallback. Use JPEG for maximum compatibility.
-
Can I compress AVIF further?Yes. AVIF files can often be further optimized, especially if generated from other formats without optimal encoding settings.
-
Does it support HDR images?AVIF natively supports HDR (High Dynamic Range) content. imgavio preserves HDR metadata during optimization.
-
Is there a file size limit?No. All processing is local with no restrictions.
