Add a PNG
Upload, drop, or paste a browser-readable PNG whose decoded dimensions are within the 12-million-pixel limit.
Free PNG to AVIF converter
Make an AVIF fromyour PNG pixels.
Use this free online PNG to AVIF converter for a browser-based raster re-encode. It decodes the PNG into a canvas and requests AVIF at 0.7 quality when that encoder is available in your browser.

About this converter
Free PNG to AVIF conversion, built for a real workflow.
PNG is commonly used where exact raster pixels and transparency matter; AVIF is a modern image format with browser-dependent canvas encoding support. Fileverses redraws the decoded PNG onto a canvas and asks the browser for AVIF at quality 0.7. Decoded alpha can remain, but the process does not preserve original PNG bytes or metadata, recover lost detail, or promise a particular file-size reduction.
- PNG is decoded into browser canvas pixels before AVIF encoding, so source bytes and original metadata are not transferred.
- AVIF is requested at canvas quality 0.7 and only appears as an output choice when this browser confirms AVIF encoding support.
- Decoded PNG transparency can remain in the AVIF result; the tool does not create alpha or remove backgrounds.
- The decoded source is capped at 12 million pixels, and conversion cannot restore detail that is not in the PNG.
- Compare the downloaded AVIF in the browsers and delivery system you support; neither file size nor visual result is guaranteed.
How it works
Upload once.
Export AVIF.
Keep AVIF selected
When your browser supports AVIF canvas encoding, AVIF is available as this page's selected output format.
Download and compare
Convert the image, download the AVIF, and inspect it at the intended display size before publishing it.
Made for real pipelines
PNG to AVIF.
One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert PNG to AVIFBrowser AVIF check
AVIF is offered only after the current browser confirms that its canvas can encode image/avif.
0.7 quality request
The encoded output is requested at a fixed 0.7 canvas quality setting rather than using a hidden quality slider.
Alpha-aware raster path
Decoded PNG alpha can pass through the canvas; no synthetic transparency or background editing is applied.
Good to know
Questions, answered.
Is PNG to AVIF conversion free online?+−
Yes. This PNG to AVIF conversion is free online and does not need an account or sign-up.
How does this PNG to AVIF tool work?+−
Your browser decodes the PNG to canvas pixels and requests an AVIF file from that canvas. It is a raster re-encode, not a transfer of the original PNG file.
What AVIF quality does Fileverses use?+−
The tool requests AVIF at quality 0.7. Browser encoders can differ, so inspect the downloaded file for your own use case.
Why is AVIF not available in my browser?+−
The converter checks whether the current browser can create image/avif from canvas. If that check fails, AVIF is not offered as an output.
Does PNG transparency remain in AVIF?+−
Transparency that survives browser decoding can remain in the AVIF output. The converter cannot add alpha or remove a background.
Will AVIF always make my PNG smaller?+−
No. Output size and appearance depend on the image and browser encoder. Conversion also does not restore detail or preserve original PNG metadata.
