PNG suits graphics, overlays, screenshots, and assets that need an alpha channel.

Create an editing-friendly PNG from an AVIF source
PNG is useful when an editor, presentation tool, or upload workflow cannot use AVIF but still needs lossless pixels or transparency. The browser decodes the AVIF and writes a new PNG locally, preserving the decoded alpha channel where one exists.
A PNG export does not recover detail already discarded when the AVIF was created. It preserves the decoded result without adding another lossy compression step, which is valuable for further editing but commonly produces a much larger file.
No quality slider is required because PNG stores the exported pixels losslessly.
Photo-like AVIF files can expand substantially when converted to PNG.
Use PNG as a working format, not automatically as a smaller format
Choose PNG when preserving transparency or avoiding another lossy encode is the priority. For ordinary photographs that only need wider compatibility, JPG will usually be considerably smaller.
Checks before downloading
- Check whether the source actually contains transparency before accepting the larger PNG size.
- Keep the AVIF original alongside the PNG working copy for future exports.
- For web delivery, compare PNG against WebP if bandwidth matters.
Questions
Are my images uploaded to ImgMini?
No. ImgMini runs the conversion in your browser. The selected files stay on your device unless you choose to share them elsewhere.
Does PNG make files larger?
Often yes. PNG is lossless, so photo-like AVIF images may become much larger after conversion.
