User Guide

How to use this tool

The ICO / Favicon Maker turns any image into the small, square icons that browsers, operating systems and RSS readers use to identify your site or application. It generates crisp bitmaps at classic favicon sizes (16×16 through 256×256) so your brand shows up sharply in tabs, bookmark bars, and search results.

How to use it

Upload a square source image — ideally 512×512 or larger — via drag & drop or the file browser. Non-square inputs will be center-fitted into a square canvas. Toggle which target sizes you want to generate; 16×16, 32×32 and 48×48 are the historical minimum, while 128×128 and 256×256 look best on Retina displays and RSS feeds.

The tool renders each requested size independently using bilinear resampling so small icons remain readable. Download the primary size as a PNG (which every modern browser accepts as a favicon) or copy the ready-to-use HTML link tags snippet from the output panel.

Multi-size output tailored to browsers, OS and RSS readers
Automatically center-fits non-square source images
Preserves transparency for logos and monograms
Includes copy-paste-ready HTML link tags

Choosing a good favicon

A great favicon reads as a single silhouette when scaled down to 16 pixels. Avoid thin strokes, dense gradients, or wordmarks longer than three characters — none of those survive small-scale rendering.

Test your favicon against both light and dark browser themes. Consider producing a monochrome variant for Safari pinned-tab support (SVG) alongside the raster favicons this tool generates.

Frequently Asked Questions

What sizes should a favicon include?

Browsers use 16px (tab), 32px (taskbar), and 48px (desktop shortcuts); our ICO bundles all three.

Do I still need a PNG favicon?

Modern browsers prefer a 32×32 PNG declared as rel="icon" type="image/png" — we generate it alongside the ICO.

What sizes should a favicon.ico include?

A modern favicon.ico should include at least 16×16 (browser tab), 32×32 (taskbar), and 48×48 (desktop shortcut). We also generate 64×64 and 128×128 for high-DPI displays.

Can I use a PNG as a favicon instead?

Modern browsers support PNG favicons, but .ico is still the most universally compatible format. For maximum compatibility, include both favicon.ico and a PNG icon in your HTML <head>.

What image format should I use as input?

Use a square PNG with transparency for best results. The input should be at least 256×256 pixels so the generated icons remain sharp at all sizes. JPG input works but does not support transparency.

Is this tool free to use?

Yes. This tool is completely free with no sign-up, no watermarks, and no daily limits. All processing runs locally in your browser.

Do modern browsers still need an .ico file?

No. Chrome, Firefox, Safari and Edge all accept PNG favicons through the link rel="icon" tag. .ico is now optional.

What size should I upload?

512×512 or larger. This gives the tool enough detail to produce every requested output size cleanly.
