Frequently asked questions
Does AVIF support transparency?
Yes, a full alpha channel, plus 10/12-bit color depth and HDR, capabilities PNG has partly and JPG entirely lacks. Transparency survives this conversion exactly.
How is this different from PNG to WebP?
Both keep transparency; AVIF typically lands another 15–25% smaller than WebP. The trade-off is encode time and slightly patchier support in older environments. For maximum compression with a modern audience, AVIF wins.
Is AVIF lossless?
It can be (AVIF supports a lossless mode), but this converter uses lossy encoding with a quality slider, which is what virtually all web use-cases want. At high quality settings, results are visually indistinguishable from the source.
