What AVIF to PNG does
AVIF to PNG validates the file container and uses the current browser's AVIF decoder before writing a PNG canvas. This provides a widely editable lossless raster output from one decoded AVIF image.
PNG can preserve decoded alpha transparency but usually requires more bytes than AVIF for photographs. Animation, HDR interpretation, auxiliary images, and container metadata are not represented in the static PNG.
How to use AVIF to PNG
- Choose one AVIF file up to 20 MB using a browser with AVIF support.
- Run the local conversion and wait while the image is decoded.
- Check the PNG appearance and file size, then download it.
Important details
Alpha can remain transparent
The PNG export does not paint a background, so alpha supplied by the browser decoder can remain transparent. Always inspect soft edges when transparency is important.
Lossless does not mean identical metadata
PNG stores the decoded raster without intentional lossy compression, but it does not copy AVIF metadata or reproduce codec-specific color and auxiliary structures byte for byte.
Practical uses
- Open an AVIF asset in an editor that supports PNG only.
- Create a transparent PNG still for a slide or compositing workflow.
- Generate a lossless-format review copy while retaining the AVIF original.
Privacy and limitations
The AVIF stays on your device while native browser decoding and PNG encoding run. No source image is uploaded to PagesTools.
One file up to 20 MB can be converted, subject to 12,000-pixel-side and 40-megapixel canvas bounds. A supported browser codec is required, and the result does not preserve animation, metadata, layers, or AVIF container features.
