SVG to ICO Converter

An SVG to ICO converter turns a vector SVG file into a multi-size ICO (icon) file. ICO is the standard format for favicons and Windows application icons. Because SVG is resolution-independent, it produces the sharpest possible results at every icon size, from 16×16 browser tab icons to 256×256 desktop icons. Use this tool when you have a logo or icon designed in a vector editor and need to generate a favicon.ico for your website or an application icon for a Windows program.

1. Upload an SVG: Drag and drop or click to select a .svg file from your device.
2. Select icon sizes: Choose which sizes to include in the ICO file. Common options are 16×16, 32×32, 48×48, and 256×256. Select all four for maximum browser and OS compatibility.
3. Download the ICO: Click the download button to save a single .ico file that contains all selected sizes bundled together.

• Best source quality: SVG is vector art. It scales to any size without losing sharpness, which means every icon size in the ICO is rendered from a perfect source.
• Multi-size in one file: A single ICO can contain 16×16, 32×32, 48×48, and 256×256 frames. Browsers and operating systems automatically pick the best size for each context.
• Favicon compatibility: While modern browsers accept SVG favicons, many platforms, CMSes, and older browsers still require favicon.ico. This tool bridges the gap.
• No design tool required: You do not need Figma, Illustrator, or a specialized icon editor. Upload the SVG and let the converter handle the rasterization.

Use case 1: Generate a favicon for a new website

Export your logo as SVG from your design tool, convert it to ICO with all standard sizes, and place the favicon.ico in your site's root directory. This covers Chrome, Firefox, Safari, Edge, and legacy browsers in one step.

Use case 2: Create a Windows desktop application icon

Windows .exe files use embedded ICO icons for taskbar, Start menu, and desktop shortcuts. Convert your SVG app icon to ICO with 16×16 through 256×256 sizes to look sharp at every display density.

Use case 3: Build a PWA icon set

Progressive Web Apps require icons at multiple sizes. Start from your SVG master, convert to ICO for the favicon, and use SVG to PNG for the manifest.json icons at 192×192 and 512×512.

Use case 4: Refresh branding across a legacy site

When rebranding, export the new logo as SVG, then generate a fresh favicon.ico to replace the old one across all properties without manually editing pixel-level icon files.

The converter rasterizes the SVG at each selected pixel size using the SVG's internal viewBox as the reference frame. This process works as follows:

1. Parse the SVG: The tool reads the SVG's viewBox, width, and height attributes to determine the aspect ratio and coordinate system.
2. Rasterize per size: For each selected size (e.g., 16×16, 32×32), the SVG is rendered to a pixel grid at that exact resolution. Vector shapes, strokes, and text are anti-aliased for clarity at small sizes.
3. Bundle into ICO: All rasterized frames are packaged into a single ICO container file. Browsers and operating systems read the ICO header and select the frame that best matches the display context.

Because rasterization happens from vector source, every frame is rendered from scratch at native resolution rather than upscaled or downscaled from a single raster. This eliminates the blurriness that comes from resizing bitmap icons.

Example 1: Create a standard favicon

• Input: logo.svg (clean vector logo with padding)
• Sizes selected: 16×16, 32×32, 48×48
• Output: favicon.ico containing three crisp frames. Place this in your site root and reference it with <link rel="icon" href="/favicon.ico">.

Example 2: Create a full-range icon for Windows

• Input: app-icon.svg (simple geometric icon)
• Sizes selected: 16×16, 32×32, 48×48, 256×256
• Output: app-icon.ico with four frames covering all Windows icon contexts from taskbar pins to desktop shortcuts.

The icon looks wrong (cropped or misaligned)

Check the SVG's viewBox attribute. If the artwork extends beyond the viewBox, parts of the image will be cut off. Add padding or adjust the viewBox in your design tool so the icon sits comfortably within the canvas, especially for the 16×16 frame where even 1 pixel of misalignment is visible.

My SVG uses external fonts

Text in SVG is rendered using the referenced font. If the font is not available during rasterization, the text falls back to a system font and may look different. Convert all text to outlines (paths) in your design tool before exporting the SVG. In Figma, use "Outline Stroke." In Illustrator, use "Create Outlines."

The 16×16 icon is hard to read

Some icons are too detailed to be legible at 16 pixels. Consider creating a simplified version of your logo for small sizes. Many brand guidelines include a "small size" mark specifically for favicons and app icons.

Colors look different between SVG and ICO

ICO uses sRGB color space. If your SVG uses a different color profile (Display P3, Adobe RGB), colors may shift slightly during conversion. For a consistent result, export your SVG in sRGB.

• Add padding in your SVG before converting. A favicon that touches the edges of its canvas looks cramped at small sizes. Leave 5-10% padding on each side.
• Test at 16×16 first. If the icon looks good at its smallest size, it will look great at every other size. Zoom your browser to 100% and check the tab icon.
• Use a square SVG with equal width and height. Non-square icons will be letterboxed or distorted inside the square ICO frames.
• For modern browsers, also add an SVG favicon alongside the ICO: <link rel="icon" type="image/svg+xml" href="/icon.svg">. This gives you the best of both worlds.
• Keep the SVG simple. Gradients, shadows, and complex strokes may not render clearly at 16×16. Flat, bold shapes work best for icons.

• Convert an existing ICO to PNG with ICO to PNG.
• Generate ICO from a raster image with PNG to ICO.
• Export a PNG preview of your SVG with SVG to PNG.
• Compress the rasterized output with compress PNG.

This conversion runs locally in your browser. Your SVG file is not uploaded to any server. All rasterization and ICO packaging happens on your device, so you can safely convert proprietary logos and brand assets.
