Convert PNG, JPG, JPEG, BMP or WebP images to AVIF, the AV1-based format that produces smaller files than WebP or JPEG at the same visual quality while still supporting HDR, a wide color gamut and transparency. Convert several at once with an adjustable quality slider — files are processed in your browser and never uploaded.

Supports PNG, JPG, JPEG, BMP, WEBPWhat is AVIF?
AVIF is a next-generation image format based on the AV1 video codec. It produces even smaller files than WebP or JPEG at the same visual quality, and it supports HDR, a wide color gamut, and even transparency. It is one of the most efficient choices when you want to minimize a web page's size as much as possible.
How to convert images to AVIF
- Select files — Click the "Input Files" area or drag and drop PNG, JPG, JPEG, BMP, or WEBP files. You can select several at once.
- Adjust quality — Use the quality slider (1-100) under "Options" to balance image quality against file size. AVIF keeps quality relatively well even at low values.
- Start conversion — Press the "Start Conversion" button and the files are converted inside your browser.
- Download — Download the converted images individually, or save them all at once with "Download All (ZIP)".
How do I set the quality?
AVIF compresses so efficiently that it keeps decent quality even at a low quality value of around 50 while greatly reducing file size. If you need a sharper result, raise the value; to shrink the file further, lower it, comparing the results as you go.
AVIF, WebP, or JPG — which should you choose?
To reduce size the most at the same quality, AVIF has the edge. However, if browser compatibility and encoding speed matter, WebP strikes a good balance, and for universal compatibility with colorful photos, JPG is a safe choice. If you need transparency or lossless quality, use PNG.
Are my images uploaded?
No. All conversion is handled entirely on your device with the browser's Canvas API, and files are never sent to a server. It even works with no internet connection, so you can safely convert sensitive images too. Add several images at once and download them individually or all together as a ZIP.
Which browsers support AVIF?
Most modern browsers such as Chrome, Edge, Firefox, and Opera support displaying AVIF, and Safari does too from version 16 onward. Very old browsers, however, may display it only partially, so if you need broad compatibility it's a good idea to also prepare WebP or JPG.
Why does AVIF conversion take longer?
Because AVIF's high compression requires more computation to encode, the same image can take a little longer to convert than WebP or JPG. The difference shows up especially when the image is large or you convert many at once.
