FAQ

JPG or PNG — which should I choose?

Use PNG for transparency or lossless detail (logos, icons). Use JPG for photos and small sizes. Simple rule: **transparency → PNG, small size → JPG**.

WebP or AVIF — which is better?

AVIF compresses more, but WebP has much better compatibility. For general audiences use WebP; AVIF suits new platforms or extreme size demands.

How do I convert an unsuitable format?

Use the [Format Convert Tool](https://img-tools.top/convert) to convert between JPG/PNG/WebP/AVIF/ICO and more, all in your browser.

Do image formats affect quality?

Yes. Lossy formats (JPG, WebP, AVIF) lose some data during compression; lossless formats (PNG, TIFF) don't. Keep originals in a lossless format for important, frequently edited images.
