Frequently Asked Questions: SVG to ICO

Does converting SVG to ICO upload my images to a remote server? ▾

Never. Every SVG file you select is decoded directly in your browser using the HTML5 Canvas API and FileReader API. Your images stay in your computer or phone RAM at all times.

Can I resize and adjust compression quality when converting SVG to ICO? ▾

Yes. Use the Quality slider (10%–100%) and the Width/Height pixel inputs above the drop zone. Keeping "Lock Ratio" checked preserves your original aspect ratio automatically.

Does this converter support batch SVG to ICO conversion with ZIP download? ▾

Yes. Drag and drop multiple SVG files at once; you can download each converted ICO individually or click "Download All (.ZIP)" to bundle them locally via JSZip.

Why use ICO instead of SVG? ▾

Converting SVG to ICO gives you multi-resolution favicon.ico bundle for browsers, Windows apps, and game clients while keeping full control over pixel dimensions and byte size.
