SVG to AVIF Converter

SVG is a vector format described in XML — instead of a pixel grid, it stores shapes and paths, so it stays crisp at any size.

Scalable Vector Graphics is, technically speaking, not an image format at all — it's an XML-based markup language that describes shapes, curves, and text mathematically rather than as a grid of pixels. That's what gives it its defining trait: an SVG can be scaled up to billboard size or down to a favicon without a single pixel of quality loss, because it's redrawn from the underlying math at whatever size it's displayed. It's also just a text file, so it can be opened and hand-edited in any code editor, styled with CSS, and even animated — which is why it's become the standard choice for logos, icons, and illustrations on the modern web.

AVIF is a newer, next-generation image format built on the AV1 video codec, delivering some of the smallest file sizes available today.

AVIF takes the intra-frame compression from the royalty-free AV1 video codec and repurposes it for still images, and the result is often noticeably smaller than an equivalent WebP or JPEG at the same visual quality. It also supports wide color gamuts, HDR, and transparency, making it one of the more technically complete image formats available. The tradeoff is encoding speed and, until recently, patchier software support — both are improving quickly as browsers and operating systems catch up.
