SVG to ICO Converter Free
Convert SVG vector graphics to ICO favicon format online for free. SVG is the ideal source for favicon creation — being resolution-independent, it renders perfectly at all ICO sizes. Generate multi-size ICO files containing 16×16, 32×32, 48×48, and 256×256 from your logo SVG. No signup required.

How It Works
Create a perfect favicon ICO from your SVG logo in three steps
Upload SVG File
Upload your SVG logo, icon, or monogram. SVG is the ideal source for favicon creation because being vector-based, it renders with perfect sharpness at all target sizes — no matter how small. Square SVGs produce the best results. If your SVG has a rectangular viewBox, the converter pads it to square before rendering.
Choose ICO Settings
Select which ICO size variants to generate and whether to use a transparent, white, or black background. Transparent is best for logos that should display cleanly on any browser theme. The SVG is rasterized at each target size using the browser rendering engine, ensuring all CSS properties, gradients, and masks in the SVG are rendered correctly.
Download favicon.ico
Get your multi-size favicon.ico ready to deploy. Place it in your website root directory alongside an SVG favicon declaration for modern browsers: <link rel="icon" href="/favicon.svg" type="image/svg+xml"><link rel="icon" href="/favicon.ico">. This gives vector-perfect rendering in modern browsers and ICO fallback for older ones.
SVG to ICO Features
The best quality favicon starts with a vector SVG source
Vector-Perfect at All Sizes
SVG is resolution-independent — the same file renders crisp at 16×16 pixels or 4000×4000 pixels. This makes it the ideal source for favicon generation: rather than downsampling a raster PNG (which introduces anti-aliasing blur), the converter rasterizes the SVG fresh at each target size, producing mathematically sharp edges and corners at every ICO variant.
Complex SVG Support
Our converter uses a full SVG rendering engine that supports the complete SVG 1.1 and SVG 2 specification: gradients (linear and radial), masks, clip-paths, filters, symbols, use elements, embedded fonts, CSS styling, and animations (first frame only). Brand logo SVGs exported from Figma, Illustrator, Sketch, and Inkscape are all handled correctly.
Multi-Size ICO Output
The converter generates a complete multi-size ICO file containing 16×16, 32×32, 48×48, and 256×256 pixel variants. Each variant is rasterized independently from the SVG at the target resolution, ensuring maximum sharpness at every size. The 256×256 variant is stored as a PNG-compressed frame within the ICO (Windows Vista+ compatible).
Transparency & Background Control
SVG files typically have transparent backgrounds. You can preserve this transparency in the ICO output (suitable for logos that should adapt to the browser's tab colour) or composite over a white or black background (useful for logos that look better with a solid base). Modern browsers respect ICO transparency and show the tab colour through transparent favicon pixels.
Modern Favicon Strategy
The current best practice is to serve both: an SVG favicon for modern browsers (Chrome, Firefox, Edge — perfect vector rendering at any DPI) and a favicon.ico fallback for Safari and IE. Declare them in this order: <link rel="icon" href="/favicon.svg" type="image/svg+xml"> then <link rel="icon" href="/favicon.ico">. Our SVG to ICO converter produces the ICO needed for this dual-format strategy.
Private & No Account Needed
All uploads use TLS 1.3 encryption. SVG files and ICO outputs are processed in isolated server containers and permanently deleted within 24 hours. No watermarks added. No account, signup, or personal information required.

Frequently Asked Questions
SVG is resolution-independent — it stores mathematical descriptions of shapes rather than pixels. This means it can render perfectly at any size without anti-aliasing blur from downsampling. When generating a 16×16 ICO from a PNG, the converter must shrink pixels, often causing blurry edges. When generating from SVG, it rasterizes the vector at exactly 16×16 from scratch, producing sharper edges and cleaner results, especially for logos with geometric shapes, text, or fine lines.
Yes — Chrome, Firefox, and Edge support SVG favicons directly via <link rel="icon" type="image/svg+xml" href="/favicon.svg">. SVG favicons scale perfectly on high-DPI displays and can even include @media (prefers-color-scheme: dark) CSS to automatically switch between light and dark variants. However, Safari has limited SVG favicon support, and IE doesn't support it at all — which is why generating an ICO fallback with our converter is still recommended.
Our converter supports the full SVG 1.1 and SVG 2 specification including: basic shapes (rect, circle, ellipse, line, path, polygon), linear and radial gradients, masks, clip-paths, filters (blur, drop shadow, etc.), transforms, groups, symbols with use elements, CSS styling (including computed styles), and embedded fonts (web fonts are loaded if accessible). SVG animations are rendered at t=0 (first frame). Externally-referenced images and fonts that require network access may not load in the server environment.
Non-square SVGs (wider or taller than they are tall/wide) are letterboxed — padded with transparent space on the shorter axis to create a square canvas before rasterization. This preserves your artwork's proportions without any cropping. If you want the ICO to show only the important part of a wide SVG (e.g. a lettermark from a full wordmark SVG), crop the SVG first in Figma or Illustrator to just the symbol portion before converting.
Yes, keep your SVG. The ICO is a rasterized copy — if you need to update your favicon later (brand refresh, colour change), you'll need to re-generate the ICO from an SVG or PNG source. Storing the SVG as part of your design system or version control is best practice. The modern favicon strategy is to also serve the SVG directly: keep the SVG in your web root alongside favicon.ico for forward compatibility.
