Does this preserve transparent AVIF images?

Yes when the browser can decode the AVIF alpha channel. PixWarp exports the result as PNG with alpha.

Why is the PNG larger than the AVIF?

AVIF uses modern lossy or lossless compression. PNG is lossless and compatibility-focused, so it is often larger.

Are my files uploaded?

No. The AVIF decode and PNG export happen inside your browser.

About this tool

AVIF is compact for modern web delivery, but PNG is easier to use in design tools, older upload forms, and workflows that need lossless pixels or transparency. PixWarp decodes AVIF in your browser and exports PNG without uploading your image.

How to use

Drop one or more AVIF images into the upload area.
02
PixWarp decodes each AVIF image locally.
03

Privacy

Processing happens in your browser whenever the tool can run locally. Your source files are not uploaded to PixWarp servers.
