What is ICO and why convert SVG to ICO?

ICO (Icon) is the native icon format used by Windows for favicons, application icons, taskbar icons, and desktop shortcuts. Converting an SVG to ICO lets you export a vector graphic as a crisp favicon or application icon — without needing Photoshop or any other software. The tool rasterizes the SVG at its declared dimensions and embeds the result as a PNG inside the ICO container.

Can I crop the SVG before converting to ICO?

Yes — the tool provides an interactive crop overlay on the rendered SVG. Drag the corner and edge handles to define exactly which portion of the SVG you want in the output ICO. For best results, crop to a square before converting. Click Preview Crop to see the result before downloading.

Does my image get uploaded to a server?

No. All processing — loading, SVG rendering, cropping, and ICO encoding — happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your file never leaves your device.

Should I crop to a square for a favicon or app icon?

Yes. Favicons and application icons are always square. Cropping your SVG to a square region before downloading ensures the ICO output has equal width and height, which is required for correct display in browsers and Windows Explorer.

What resolution is the ICO output?

The output ICO is rasterized at the natural pixel dimensions the browser assigns to the SVG when rendered. For SVGs with an explicit width and height attribute, this is typically that declared size. The crop is applied at full resolution. The ICO embeds a PNG payload at the cropped pixel dimensions.

How do I reset and convert a different image?

Click the Start Over button that appears after loading an image. This clears the current file and resets the crop area so you can load a new SVG.

What This Tool Does

This tool loads an SVG file directly in your browser using URL.createObjectURL and img.decode() for reliable, guaranteed non-blank rendering. The browser rasterizes the SVG at its declared pixel dimensions. It presents an interactive crop overlay with draggable handles, and converts the selected area to an ICO file. No server upload is required. The full workflow — loading, rendering, cropping, and ICO encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. The output is a single-image ICO file with a PNG-embedded payload, compatible with all major browsers, Windows Explorer, and icon editors.

Who This Is For

Designers who need to export a specific region of an SVG illustration as a favicon or application icon
Developers who want to generate a crisp ICO file from an SVG logo without installing Inkscape or Photoshop
Anyone preparing favicon assets for websites who wants to crop to the exact icon area before exporting to ICO
Users building Windows applications or desktop shortcuts who need square icon assets from SVG source files

Frequently Asked Questions

What size should I crop to for a favicon?▼

The most universally recommended favicon size is 32×32 pixels, though modern browsers also use 16×16, 48×48, and 192×192 variants. For best results, crop to a square region that contains the most recognizable part of your SVG, then the ICO output will use those pixel dimensions. If you need a specific pixel size, use the Image Resizer tool as a follow-up step.

How precise is the crop tool?▼

The crop operates at native pixel accuracy on the rendered SVG dimensions. The canvas is scaled to fit your screen for display, but the actual crop coordinates are mapped back to the full-resolution image before the ICO is generated. You get an ICO at the exact pixel dimensions shown in the crop dimensions badge.

Can I move the crop selection after setting it?▼

Yes — click and drag anywhere inside the crop rectangle (away from the handles) to reposition it anywhere within the image. Handles resize; the interior pans.

Does the output ICO support transparency?▼

Yes. The tool embeds a PNG inside the ICO container, which preserves full 32-bit RGBA transparency. If your SVG has transparent regions (or you crop to a subject with transparent edges), that transparency will be retained in the ICO output.

What browsers are supported?▼

All modern browsers — Chrome, Firefox, Edge, Safari (desktop and mobile). The tool uses standard HTML5 Canvas and Blob APIs that have been universally supported since 2015.

Is there a file size limit?▼

There is no server-imposed limit because no upload occurs. The practical limit is your browser's available RAM. Most modern desktops handle SVG files comfortably. Very large or complex SVGs may take slightly longer to rasterize.
