Is this SVG to ICO converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple SVG files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

Why is SVG the best source for creating a favicon ICO?

SVG is vector-based and resolution-independent, so it renders crisp edges at every icon size (16, 32, 48 px). Raster sources like PNG can look blurry when scaled down to 16×16.

Can I also use an SVG directly as a favicon without converting to ICO?

Modern browsers support SVG favicons via . However, for maximum compatibility — including older browsers and Windows pinned sites — an ICO file is still recommended.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert SVG to ICO?

SVG is the ideal source format for creating favicons and application icons — it's scalable, so it produces sharp results at every icon size. But browsers and operating systems use ICO as the favicon format, not SVG (though modern browsers support SVG favicons, older browsers and all versions of Windows Explorer still require ICO for full compatibility).

Converting SVG to ICO generates a multi-resolution icon container that includes the 16×16, 32×32, and 48×48 pixel sizes browsers and Windows need. The scalable nature of SVG means the converter can render the icon precisely at each target size, giving you sharper results than converting from a fixed-size raster source. For this reason, SVG is actually the best possible starting point for ICO creation.

For best results, the SVG should be a square graphic with a clean, bold design. Complex illustrations with fine detail won't be readable at 16 pixels wide, so simplify the design before converting if needed. After generating the ICO, test it with a favicon checker tool — view it in multiple browsers, check how it looks on mobile home screens, and verify the Windows taskbar appearance. Tools like RealFaviconGenerator can further optimize the ICO for cross-platform deployment. Most modern sites also include a separate SVG favicon tag alongside the ICO for browsers that support it.

Quality & file size: SVG to ICO

Typical file sizes: SVG 5–50 KB → ICO 10–100 KB.

Both SVG and ICO use lossy compression. We transcode at high quality settings (equivalent to ICO's recommended web quality) to minimize generational loss.

Color depth: SVG supports unlimited (vector), ICO supports standard color.

Transparency: SVG supports transparency. ICO preserves transparency.
