What size source image should I upload?

At least 512x512 px. Browsers downscale your image to each target size, so a 512+ source has enough detail to produce a sharp 192x192 home-screen icon. Smaller sources (256 px or less) lose detail when scaled up to 512 for Android, and may look pixelated. Square is required, non-square sources get centre-cropped.

Why do I need so many sizes? Doesn't favicon.ico cover everything?

It used to. Modern devices ask for higher-resolution icons in specific formats: iOS uses a separate 180x180 apple-touch-icon for the home screen, Android pulls a 192x192 or 512x512 PNG for its launcher, and Safari uses an SVG for the pinned-tab sidebar. A single .ico, while still required for legacy browsers, no longer covers everything.

Will the generator handle a logo that has fine details?

It tries, but 16x16 is fundamentally too small for fine detail. If your logo has a thin script font or intricate filigree, those features will smear at the smallest size. The pragmatic fix is to design a simplified version of the logo specifically for the 16/32 sizes, a single letter or a recognisable symbol, and let the full logo appear at 192 and above.

Does the generated SVG support animation or hover states?

No. The Safari pinned-tab SVG is a single static path with one fill color, that is the spec. For animated favicons (the tab icon spinning while a page loads), use JavaScript at runtime to swap the favicon's href, which is independent of the generated pack.

Can I use a non-square image?

The generator centre-crops to square before resampling. If the important content of your logo is off-centre or extends to the edges of a non-square design, crop it to square first using our Crop Image tool with a 1:1 locked aspect ratio. That way you control which part of the image survives the crop.

Is the source image uploaded anywhere?

No. The entire resampling and ZIP packaging happens in your browser. The source image is read into memory, processed, and the resulting ZIP downloads directly, no server is involved. This makes the generator safe to use for logos that are still under NDA or pre-launch.

What is Favicon Generator?

A favicon is one of those tiny details that quietly tells visitors your site is real. The browser tab, the bookmark bar, the homescreen icon on iOS and Android, the small thumbnail in Google's mobile search results, they all pull from the same icon. Producing it well used to mean exporting ten separate PNGs at different sizes, then writing four lines of HTML link tags by hand. This generator does both steps in one pass: drop a source image, get back a ZIP containing every size modern browsers and devices ask for, plus the exact HTML snippet to paste into your `<head>`. The pack includes the classic favicon.ico (16, 32 and 48 px combined), the apple-touch-icon (180x180), Android home-screen icons (192 and 512 px), and a Safari pinned-tab SVG. The HTML snippet uses the modern `<link rel="icon">` syntax with appropriate `sizes` and `type` attributes, no shim, no legacy XML.

Why use this tool?

Generation runs entirely in your browser on a Canvas, the source image is decoded once, then resampled to each target size using high-quality bilinear interpolation. Output is bundled into a ZIP that you can drop directly into your site's `/public/` or web root. No server upload, no account, no watermark. The generator preserves transparency through the resize, so a PNG logo with an alpha cutout exports as transparent icons at every size, important for the apple-touch-icon and the Safari pinned-tab SVG, both of which look badly on a white background unless transparency is preserved.

Common use cases

Any time you launch or rebrand a website. The favicon is the small but visible signal that the site is finished, sites without one often look unfinished or untrustworthy. Personal blogs, landing pages, internal dashboards, side projects, every web project benefits from this 30-second setup. Other workflows: producing a webapp icon for a PWA (Progressive Web App) that users install to their home screen; generating a single 512x512 source for OpenGraph and Twitter cards; updating an existing favicon after a logo refresh, the generator outputs identical files names so the old icons get replaced cleanly when you upload the new pack. For multi-platform brand assets beyond the web (app store, social media profile photos), follow up with our Resize Image tool to produce the platform-specific sizes.

How to use Favicon Generator

3Preview each size to confirm visual fidelity at the smallest 16x16
4Download the ZIP, drop the files into your site's web root or /public/
5Paste the provided HTML snippet into your <head>

Pro tips

1Test the 16x16 size on a real browser tab, not just in the preview. Browser tabs scale the icon down with a different rendering path than the static preview, and what looks crisp at 16 px in the preview can blur slightly in the real tab.
2For dark-mode-aware sites, you can ship two favicons and use the `prefers-color-scheme` media query in the `<link>` tag to swap them. The generator does not produce this automatically, but you can run it twice (light source, then dark source) and pick the icon files for each scheme.
3Embed your favicon as a base64 data URL inline in HTML for the 16/32 sizes to skip the extra HTTP request and avoid the brief tab-icon flash on first load. Small icons (~1-2 KB encoded) are usually a net win to inline.

How does it compare?

Online generators like realfavicongenerator.net upload your source image to their servers and email or display the result. This tool does the same job entirely in your browser, no upload, no email, no account, and the output ZIP is the same set of files.
