Favicon generator — PNG/SVG to multi-size ICO
Turn a logo or square mark into a site favicon: multiple sizes packed into one `.ico` for sharper tabs, bookmarks, and some shortcuts. Start with a simple centered square on a clean background — dense detail collapses into mud at 16×16.

The favicon is the tiny mark users spot in a tab. Many sites also ship PNG in a web manifest, but ICO remains a solid multi-size bundle for broad compatibility.
Square sources work best. Wide logos get letterboxed or cropped depending on fit mode — crop square first if needed.
Strong contrast wins at small sizes: thin light-gray lines disappear in the tab bar. Bold shapes beat tiny text.
How to generate
- Upload the most square logo you have
- Pick size set and fit mode
- Download favicon.ico
- Place at site root or link per your framework docs
What the generator saves you
- Packs common sizes in one go so you do not miss 16 or 32.
- Downloads a ready `.ico` — no hand-building the file.
- Upload a square logo and hang it on the site quickly.
Who needs this
- New site with no tab icon yet
- Rebrand color update for the favicon
- Quick ICO from a PNG logo for a traditional host
Design tips
- Source at least 256×256 or vector SVG scales cleaner.
- Do not cram a full tagline into the icon.
- Open a real browser tab after generating to sanity-check.
- PWAs may still need separate PNG entries in the manifest.

Favicon FAQ
- Can I use PNG alone as favicon?
- Many modern browsers allow it. ICO still helps older environments; both together is common.
- SVG as the only favicon?
- Support is growing, but ICO/PNG combo remains safer.
- Why is 16×16 unreadable?
- Too much detail in the source. Simplify or design a dedicated tiny mark.
