Why use PixelTools to convert svg to ico
Rendered from vector, not a screenshot
The SVG is rasterized at high resolution from its own geometry before the favicon sizes are cut, so shapes stay crisp instead of inheriting a low-res bitmap's edges.
Multi-size favicon in one file
Packs 16×16, 32×32, and 48×48 frames into a single .ico, matching what dedicated favicon generators produce.
100% browser-based
Your SVG never leaves your device — the ICO container is assembled locally, no upload, no server.
Batch conversion
Drop several SVGs at once and download every generated icon individually or together as a ZIP.
Three steps to convert svg to ico
- 1
Drop your SVG
Select or drag the .svg file — typically a logo or icon mark exported from Figma, Illustrator, or Inkscape. The browser reads it locally, no upload involved.
- 2
Rasterize at favicon sizes
The SVG is rendered from its viewBox at high resolution, then reduced to 16×16, 32×32, and 48×48 pixels — preserving transparency — and each size is exported as a PNG frame.
- 3
Pack into an ICO container and download
Those three frames are written into one .ico, each listed in the container's directory with its size and offset, so browsers and Windows can pick whichever size they need.
Who converts SVG to ICO?
SVG is how most modern logos are designed and exported, but favicon.ico is still the fallback every browser and OS checks first. People converting SVG to ICO are usually finishing a site's favicon setup after designing the mark as vector.
Favicon fallback for a vector brand mark
Modern browsers accept an SVG favicon, but Windows, older browsers and most bookmark systems still look for favicon.ico. Converting the same vector mark gives you the fallback without redrawing anything.
Figma and Illustrator logo exports
Design tools export logos as SVG by default, usually with no fixed width or height. Those go straight to a favicon here without a detour through a raster editor to set a canvas size first.
Design systems keeping one source of truth
When the logo lives as vector in the design system, generating the .ico from that same file keeps the favicon in step with brand updates instead of drifting from an old exported PNG.
Documentation and static site generators
Docusaurus, MkDocs and similar generators ship a favicon.ico slot in their theme config. A vector logo has to be rasterized and packed before it can fill it.
Frequently asked questions
Why convert SVG to ICO instead of using the SVG directly as a favicon?
+
Modern browsers can use SVG favicons, but Windows, older browsers, and many bookmark/shortcut systems still only read .ico. Converting gives you a favicon.ico fallback that works everywhere the modern SVG link tag doesn't.
What sizes are packed into the ICO file?
+
The SVG is rasterized at 16×16, 32×32, and 48×48 pixels and all three are packed into a single .ico file — the standard set for browser favicons and Windows shortcuts.
Will my vector logo stay sharp at 16×16?
+
Your SVG is rasterized at high resolution and each favicon size is scaled down from that, so edges stay clean — simple logos and wordmarks with bold shapes hold up well, while very fine detail and small text can still get lost at 16×16.
What if my SVG has no width or height set?
+
That's the normal "responsive" export from Figma and Illustrator, and it's handled — the SVG is rendered from its viewBox at a fixed high resolution before the icon frames are cut, so the artwork fills the icon instead of landing in a corner.
Does transparency carry over?
+
Yes. Any transparent background in the SVG is preserved through rasterization and into the ICO's PNG-format frames.
Are my files uploaded to a server?
+
No. The SVG is rendered and packed into the ICO container entirely in your browser. Nothing is uploaded or stored.
