About this tool

AVIF can deliver excellent compression for photos and graphics, often outperforming WebP and JPEG at the same visual quality. Canvas-based AVIF encoding is not available in every browser — if export is unsupported, a clear warning is shown; try WebP or PNG using the links above.

Upload your image, wait for conversion, preview the original versus the AVIF output, compare file sizes, and download — with no server-side storage. Everything runs locally in your browser using the Canvas API.

Frequently asked questions

Quick answers about this free online tool.

Upload a JPG, PNG, or WebP file. The image is drawn to an HTML canvas in your browser and exported as AVIF — nothing is uploaded to a server. Then preview the result and download.

Output uses lossy compression at a fixed quality setting (0.8) for a balance of size and visual quality. Results vary by image content.

No. Conversion runs entirely in your browser using the Canvas API. Files are not sent to us or stored.

JPEG, PNG, and WebP uploads are supported, up to 25 MB. Very large dimensions are scaled down so the canvas stays within safe browser limits.

AVIF encoding from canvas is not available in all browsers. Use a recent version of Chrome or Edge, or try WebP/PNG instead.
