Get to know this tool
The Favicon Generator converts any logo or image into a complete, production-ready favicon set — a multi-size favicon.ico, PNG icons at every size modern platforms expect, and the apple-touch-icon used on iOS home screens — entirely in your browser. Your logo is never uploaded; every resize and every file is produced locally with the canvas API.
What is a favicon and which sizes do you need?
A favicon is the small icon browsers show in tabs, bookmarks, history, and search results. There isn't one single size anymore: browser tabs use 16×16 and 32×32, Windows taskbar pins prefer 48×48, iOS home-screen shortcuts request a 180×180 apple-touch-icon, and Android/PWA manifests expect 192×192 and 512×512. This tool renders all of them from one source image and also packs the classic sizes into a single favicon.ico that works everywhere, including very old browsers.
Key Features
- Complete Set in One Click: 16, 32, 48, 180 (Apple), 192 and 512 px PNGs plus a multi-size
favicon.ico(16+32+48). - True ICO Output: The
.icofile is assembled in the browser with the real ICO container format — not just a renamed PNG. - High-Quality Scaling: Uses the canvas API's high-quality smoothing; non-square images are center-cropped automatically.
- Transparency Preserved: PNG alpha channels survive the conversion — checkerboard previews show exactly what's transparent.
- Ready HTML Snippet: Copy the
<link>tags for your<head>with correct file names and sizes. - 100% Client-Side Privacy: Your logo never leaves your device; all rendering happens locally.
How to Use the Favicon Generator
- Drop in a square image — ideally 512×512 or larger (PNG with transparency works best).
- Preview every generated size in the grid.
- Click Download favicon.ico for the classic multi-size icon, and download the PNG sizes you need.
- Copy the HTML snippet into your site's
<head>and place the files in your site root.
Why Choose This Tool?
Favicon services that require an upload put your unreleased logo on someone else's server. This generator does the same job locally, produces a genuine multi-image .ico (many free tools fake it with a single renamed PNG), and hands you the exact HTML markup — no email walls, no watermarks, no size limits.
Frequently Asked Questions (FAQ)
What source image should I use?
A square PNG of at least 512×512 with a transparent background gives the best results. Simple, bold shapes survive the reduction to 16×16 far better than detailed images.
Is a favicon.ico file still necessary?
It's still the safest baseline: browsers request /favicon.ico by default, and legacy software only understands ICO. Serving it alongside PNG <link> tags covers every platform.
My image isn't square — what happens?
The tool automatically crops it to a centered square before scaling. For full control, crop the image yourself first (the image resizer tool on this site can help).
Is my logo uploaded anywhere?
No. The image is read with the File API and every icon is rendered with the canvas element in your browser. Nothing is transmitted.
Why does my icon look blurry at 16×16?
Sixteen pixels is tiny — fine details and thin text simply can't survive. Use a simplified version of your logo (a monogram or symbol) for the smallest sizes if the full logo becomes unreadable.
