What sizes does the ICO file contain?

Each ICO output contains six embedded PNG frames: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. Modern Windows and browsers select the best size automatically.

Why convert SVG to ICO?

ICO is the standard format for Windows application icons and browser favicons. SVG logos and icons are ideal source art for ICO because their vector nature renders crisply at every embedded size.

Does my data get uploaded to a server?

Never. All SVG rendering and ICO encoding happens entirely in your browser using JavaScript. Your files never leave your device.

What software opens ICO files?

ICO files open natively in Windows Explorer, web browsers (as favicons), GIMP, Photoshop (with a plugin), and most professional image editors.

Web developers who need a pixel-perfect favicon from an SVG logo
Windows app developers who need an ICO file for application and taskbar icons
Designers converting SVG brand marks into multi-size icon assets
Anyone who needs a quick ICO from an SVG file without installing software

How It Works

Drop your SVG filesDrag one or more .svg files onto the drop zone, or click Browse Files. Thumbnails generate immediately using the browser's native SVG renderer.

Click Convert to ICOThe SVG is rendered to an HTML Canvas at high resolution; the ICO encoder scales to six sizes and builds a standards-compliant ICO binary entirely in memory.

Download your ICOsDownload files individually or check "Download as ZIP" for a single timestamped archive. The tool resets after export.

🔒 Privacy & Security

All rendering and encoding runs entirely in your browser. SVG files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for proprietary brand assets and unreleased icon work.

Frequently Asked Questions

What sizes does the output ICO contain?▼

Each ICO file contains six PNG frames: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. Windows and browsers automatically select the most appropriate size for the context.

Why is SVG a great source for ICO?▼

SVG is resolution-independent vector art. Unlike raster sources (JPG, PNG), an SVG logo renders at any size without pixelation. This means all six ICO frames — from 16×16 to 256×256 — are drawn from the same crisp vector source, giving you the sharpest possible icon at every size.

Can I use the ICO as a favicon?▼

Yes — ICO is the original favicon format. Rename the output to favicon.ico and place it in your website root. All browsers will use it automatically, selecting the most appropriate embedded size.

Can I convert multiple SVG files at once?▼

Yes — drop multiple SVG files at once. The tool processes them sequentially, shows per-file status badges, and lets you download all ICOs individually or as a single timestamped ZIP.

Is this tool free with no limits?▼

Yes — completely free with no file size limits, no per-conversion limits, and no account required. Processing happens in your browser so we never see your files.

What is the ZIP file named?▼

The ZIP is named dataconversioncenter_svg_to_ico_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_svg_to_ico_202603051709.zip.
