SVG is the best possible source for a favicon. A vector logo rasterizes cleanly at every size — no pre-existing compression artifacts, no pixel blur from upscaling, just mathematically precise edges rendered at the exact target resolution. Converting your SVG logo to ICO using Enhydra RPO is the textbook favicon workflow: the vector is rasterized at high resolution, then downscaled to generate six embedded sizes, and those six sizes are bundled into a single ICO file ready to drop at your site root.
The output ICO contains sizes at 16, 32, 48, 64, 128, and 256 px. Transparency defined in the SVG — transparent fills, cutouts in the logo — is preserved in each embedded ICO size, so the icon sits cleanly against any browser chrome color. You do not need to pre-export the SVG to PNG first; Enhydra RPO handles the rasterization step internally.
When a raster source (JPG, PNG) is used for ICO generation, the quality of each embedded size is limited by the original pixel resolution. If the source is 64×64 and you need a 256×256 embed, the upscaled result is soft. Scaling down works better than up, which is why the standard advice is to start with at least 512×512 px.
SVG has no resolution ceiling. The converter rasterizes it at whatever target size is needed — 256 px, 512 px, or higher — from the vector geometry itself. The 256×256 embed in the ICO is as sharp as if you had painted it at 256×256 natively. The 16×16 embed is generated from the same source, not scaled down from the 256. The result is consistently sharper than raster-source ICO files, especially at the small sizes that users see most often.
Crispness at render time does not automatically mean legibility at 16×16 px. A complex SVG logo — detailed illustration, multiple text elements, intricate geometry — will be sharp but unreadable at small sizes because there simply are not enough pixels to represent the detail.
Effective favicons from SVG sources are typically:
If your SVG logo includes a wordmark beside the symbol, the favicon should use the symbol portion only. Most SVG design tools let you export a selection or an artboard; use that to isolate the mark before uploading.
SVG elements with fill: none or explicit transparent fills are treated as transparent during rasterization. This transparency carries through into every embedded ICO size. The icon will render correctly against white browser tabs, dark mode tabs, colorful OS taskbars, and any other context — without a white or black box around it.
SVG files that use a white rectangle as a background instead of a transparent canvas will produce ICO files with a white background. Check your SVG in a viewer against a non-white background before converting if transparency matters for your use case.
Common SVG features — fills, strokes, gradients, basic transforms, groups, and clipping paths — are supported. Very complex filters or embedded fonts may render differently than in a full browser SVG renderer. Test your result if your SVG uses advanced effects.
A viewBox attribute is what the rasterizer uses to determine proportions. If your SVG has a viewBox, dimensions work correctly. If it has only width/height attributes and no viewBox, ensure they are set to the intended square dimensions.
Yes. Upload up to 200 SVG files in one run; each produces its own six-size ICO file, all delivered in a single ZIP download.
For most cases, yes — uploading the SVG directly skips one lossy or intermediate export step and lets the rasterizer work from the vector geometry. If your SVG relies on features that do not render correctly, a clean PNG export at 512×512 or larger is the reliable fallback.
