Add JPG files
Drop, choose, or paste JPG files. The browser accepts up to 50 files, each under 50 MB, and conversion rejects images above 12 megapixels.
Free JPG to AVIF converter
Convert JPG toAVIF in your browser.
Free JPG to AVIF conversion creates a new AVIF from browser-decoded JPG pixels. It uses canvas AVIF encoding at quality 0.7, so check the downloaded image in the browsers and workflow where you will use it.

About this converter
Free JPG to AVIF conversion, built for a real workflow.
JPG is already a lossy, opaque raster format. This converter decodes that visible image in your browser and asks the browser to make a new AVIF at quality 0.7. AVIF can be useful for a modern delivery workflow, but this is not a lossless container swap: it cannot restore JPG detail, create transparency, preserve the original bytes, or promise a smaller download. Compare the result in the destination browser before replacing a production asset.
- The browser decodes the JPG into pixels before AVIF is encoded; original JPG bytes and metadata are not carried over.
- The AVIF request uses canvas quality 0.7, so this is a new lossy encode rather than quality recovery.
- JPG has no alpha channel; converting it does not create transparent areas in the AVIF result.
- AVIF availability depends on the current browser: the page hides this output when its canvas encoder is unavailable.
- Output size and visible detail depend on the image and browser encoder; test the downloaded AVIF in its intended delivery path.
How it works
Upload once.
Export AVIF.
Keep AVIF selected
AVIF is the route default when this browser reports that it can create AVIF from canvas. Leave it selected to use the 0.7 quality encode.
Convert and check
Create the files, download each AVIF, and inspect it in the browser or CMS that will serve it before replacing the JPG.
Made for real pipelines
JPG to AVIF.
One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert JPG to AVIFBrowser-only processing
The JPG is decoded and the AVIF is created in the current browser, without a conversion-server upload.
Known encode setting
This route requests a 0.7 canvas AVIF quality setting, making it clear that the result is a fresh lossy encode.
Batch workspace
Queue multiple browser-readable images, convert them in sequence, and download each completed AVIF individually.
Good to know
Questions, answered.
Is this JPG to AVIF converter free?+−
Yes. The JPG to AVIF converter is free, online, and does not require an account or sign-up.
Are JPG files sent to a server?+−
No. This converter decodes and encodes the image in the browser; the JPG is not posted to a conversion server.
What AVIF quality does this tool use?+−
It asks canvas to encode AVIF at quality 0.7. The exact output remains browser-dependent, so review the downloaded file.
Can JPG to AVIF add transparency?+−
No. A JPG has no alpha channel, and conversion cannot invent transparent pixels or remove a background.
Will the AVIF file always be smaller?+−
No. File size depends on the source image and the browser encoder. Compare the downloaded AVIF with the JPG for the intended use.
Why is AVIF unavailable in my browser?+−
The page checks whether the current browser can create AVIF from canvas. If that encoder is unavailable, AVIF is removed from the output choices.
