AVIF vs HTML SVG
Which image format should you choose?
AVIF wins on best-in-class compression. HTML SVG wins on no file needed — paste markup or fetch from a url. For most general use, pick whichever is more compatible with your existing tools — file size and quality differences are usually small at the same encoding settings.
When to use AVIF
Choose AVIF when you need cutting-edge web performance and seo or hero images and photography on modern sites. Its strengths: best-in-class compression, and hdr and wide color gamut support.

When to use HTML SVG
Choose HTML SVG when you need saving an inline <svg> from a website as a real .svg file or turning a code-editor svg snippet into png or webp. Its strengths: no file needed — paste markup or fetch from a url, and extract any inline svg straight from a web page.
Pros
- + No file needed — paste markup or fetch from a URL
- + Extract any inline SVG straight from a web page
- + Convert to a clean standalone .svg or any raster format
Cons
- − Inline SVGs can reference external fonts or CSS that won't be embedded
- − Markup pasted from HTML may include surrounding elements to strip
- − Not a real file format — it's SVG markup living inside HTML
