What is a Favicon Generator?
A favicon is the small icon that appears in browser tabs, bookmarks, mobile home screens, and search results. Every professional website needs one — but producing the correct sizes and formats for every platform manually is tedious. A favicon generator takes a single source image and produces every size and format you need in one step.
ToolSnap's favicon generator runs entirely in your browser. Upload a square PNG, JPEG, or SVG and download a complete favicon package — ICO, PNG sizes, Apple Touch Icon, and a ready-to-use web manifest snippet. Your image never leaves your device.
What Sizes Do You Need?
Modern browsers and platforms expect multiple favicon sizes:
- 16×16 — Standard browser tab icon
- 32×32 — HiDPI/Retina browser tabs
- 48×48 — Windows taskbar
- 180×180 — Apple Touch Icon for iOS home screen
- 192×192 — Android Chrome and PWA icons
- 512×512 — Android splash screen and PWA install
Providing only one size forces browsers to scale down, often producing blurry or unrecognizable icons at 16×16 pixels.
Recommended HTML Setup
After generating your favicons, add these tags to your site's <head>:
<link rel="icon" href="/favicon.ico" sizes="any" />— Universal ICO fallback<link rel="icon" href="/favicon.svg" type="image/svg+xml" />— Scalable SVG (Chrome, Firefox, Edge)<link rel="apple-touch-icon" href="/apple-touch-icon.png" />— iOS home screen<link rel="manifest" href="/site.webmanifest" />— Android PWA manifest
Source Image Tips
- Start at 512×512 or larger — You can scale down cleanly, but scaling up creates blur.
- Use a square image — Non-square sources get cropped or padded unpredictably.
- Keep it simple — Fine details disappear at 16×16. Bold shapes and strong contrast work best.
- Test at small sizes — Preview how your icon looks at tab size before publishing.
- Avoid photos — Photographic favicons become unrecognizable blobs at small sizes.
Frequently Asked Questions
What is the difference between ICO and PNG favicons?
ICO is a container format that can bundle multiple sizes (16×16 and 32×32) in a single file — the traditional universal fallback. PNG favicons are simpler and widely supported in modern browsers. Best practice is to provide both: ICO for legacy support and PNG/SVG for modern browsers.
Does SVG favicon work everywhere?
SVG favicons are supported in Chrome, Firefox, and Edge and offer perfect scaling at any size. Safari does not support SVG favicons as of 2026, so always keep a PNG or ICO fallback.
Why does iOS need a separate Apple Touch Icon?
When users add your site to their iOS home screen, iOS looks for apple-touch-icon.png at 180×180. Without it, iOS takes a screenshot of your page instead — which rarely looks good.
