Frequently Asked Questions: ICO to SVG

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

Never. Every ICO 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 ICO to SVG? ▾

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 ICO to SVG conversion with ZIP download? ▾

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

Why use SVG instead of ICO? ▾

Converting ICO to SVG gives you self-contained XML vector wrapper with embedded high-DPI canvas output while keeping full control over pixel dimensions and byte size.
