How SVG to WebP conversion works
SVG is a text-based vector description; WebP is a grid of pixels. Converting means rasterizing: the browser renders the SVG onto a canvas at the width you choose, then encodes that canvas to WebP. Because rendering happens in your own browser engine, the result matches exactly what you see on screen, including fonts that are installed on your machine.
Choosing the right size
Unlike photos, there is no 'original' size for an SVG, so the maximum width setting is the output width. Common targets: 1200×630 for Open Graph images, 1080 px for Instagram, 512 px for app icons, and 2× the CSS size for sharp logos on high-DPI screens.
Fonts and external resources
If your SVG references web fonts or external images, they may not load when rasterized locally. Convert text to outlines in your vector editor before exporting for the most reliable result.
