Free WEBP to AVIF converter
Convert WEBP toAVIF in your browser.
Free WEBP to AVIF conversion creates a new AVIF from browser-decoded WebP pixels. The current browser is asked to encode AVIF at quality 0.7, so compare the download in the browser or delivery workflow where you plan to use it.

About this converter
Free WEBP to AVIF conversion, built for a real workflow.
WebP and AVIF are both modern raster formats, but this tool is a fresh pixel-based re-encode rather than a lossless file swap. It draws the browser-decoded WebP into a canvas and asks that browser to create an AVIF at quality 0.7. Decoded transparency can remain in the canvas result, while original WebP bytes, metadata, and compression history do not transfer. AVIF is offered only when the active browser reports canvas AVIF encoding support, and neither its size nor its visible result is guaranteed to match the source.
- The browser decodes the WebP into pixels before requesting a new AVIF; original WebP bytes and metadata are not copied over.
- AVIF encoding is requested from canvas at quality 0.7, making this a new lossy encode rather than a quality-recovery step.
- If the browser-decoded WebP has alpha, that decoded transparency can remain in the canvas output; conversion cannot create transparency that is absent.
- The page removes AVIF from its output choices when the current browser cannot create an AVIF blob from canvas.
- File size and visible detail depend on the source and browser encoder, so validate the downloaded AVIF in its intended delivery path.
How it works
Upload once.
Export AVIF.
Keep AVIF selected
AVIF is the default for this route when the current browser supports canvas AVIF encoding. It uses the route's 0.7 quality request.
Convert and compare
Create the AVIF files, download them, and check the results where they will actually be served or opened.
Made for real pipelines
WEBP to AVIF.
One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert WEBP to AVIFBrowser-side conversion
The WebP is decoded and the AVIF is created in the current browser without a conversion-server upload.
Known AVIF request
The route requests canvas AVIF quality 0.7, clearly identifying the result as a fresh encode.
Batch workspace
Queue several browser-readable images, process them in sequence, and download each completed AVIF individually.
Good to know
Questions, answered.
Is the WEBP to AVIF converter free?+−
Yes. This WEBP to AVIF converter is free, online, and available without an account or sign-up.
Are WEBP files sent to a conversion server?+−
No. The image is decoded and the AVIF is created in the browser; the WEBP is not posted to a conversion server.
What AVIF quality does this tool use?+−
The tool requests canvas AVIF encoding at quality 0.7. The exact file remains dependent on the browser, so review the downloaded image.
Will my WEBP transparency remain in AVIF?+−
Decoded alpha can remain when the browser draws the WebP into canvas and creates the AVIF. The converter cannot add transparency or remove a background.
Will the AVIF always be smaller than the WEBP?+−
No. Output size depends on the image and the browser's encoder. Compare the downloaded AVIF with the WebP for your actual use.
Why is AVIF not available as an output?+−
The page checks whether the current browser can create AVIF from canvas. If that encoder is unavailable, AVIF is removed from the output choices.
