Is this GIF 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 GIF 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.

Will my animated GIF become an animated ICO?

No — ICO does not support animation in standard use. The converter uses the first frame of the GIF. For static logos and icons, this works perfectly.

GIFs are only 256 colours — will the favicon look bad?

For simple logos and icons with flat colours, 256 colours is usually sufficient and the favicon will look fine. For complex images with gradients, start from a PNG or WebP source instead.

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 GIF to ICO?

GIF images are sometimes used as simple graphics, logos, or icons — and occasionally you need to use one of these as a favicon or Windows application icon. Browsers and Windows expect icons in ICO format, not GIF, so you need to convert before the icon can be deployed.

ICO is a container format that packages one or more sizes of an icon (16×16, 32×32, 48×48 pixels) into a single file. When you convert a GIF to ICO, the image is scaled to the appropriate sizes and packed into the ICO container. Browsers select the most appropriate size automatically based on where the icon is being displayed — the tiny browser tab, the larger bookmark manager entry, or a home screen shortcut.

GIF's 256-color limit is actually an advantage here — simple, flat-color graphics with few colors convert to ICO cleanly. The limited palette that's a drawback for photos is often appropriate for icon-scale graphics. Transparent areas in GIF (using the single transparent color index) are preserved in ICO. For animated GIFs, only the first frame is used for the ICO, since ICO doesn't support animation. If the GIF source is a simple logo or symbol with clean edges and flat colors, the ICO result will look sharp even at 16×16.

Quality & file size: GIF to ICO

Typical file sizes: GIF 1–5 MB → ICO 10–100 KB.

Both GIF and ICO use lossless compression, so no quality is lost in conversion. The output ICO file will be visually identical to the GIF source.

Color depth: GIF supports 8-bit, ICO supports standard color.

Transparency: GIF supports transparency. ICO preserves transparency.
