Favicon Generator: Create Favicons for Every Device From One Image
A favicon is the small icon that appears in a browser tab, a bookmark list, a Windows site tile, an iOS home screen, and an Android splash screen. What looks like a single image is actually a family of files at different sizes, each tuned for a specific surface. Hand-producing every size in a graphics editor is tedious and error-prone, and a missing size often means a blurry or default icon on some device.
The Favicon Generator solves this by turning one uploaded image into eight correctly named, correctly sized PNG files plus a ready-to-paste HTML snippet. You upload once, preview the results, and download exactly the files your project needs.
Everything runs locally in your browser via the Canvas API. Your image is never uploaded to a server, which makes the tool suitable for unreleased logos, client work under NDA, and personal branding assets alike.
Why Use the Favicon Generator?
- One upload, eight sizes. Supply a single square image and receive every size a modern site needs, from the 16px browser-tab icon to the 512px PWA splash graphic.
- Completely client-side. The image is processed in-browser through the Canvas API, so no file ever leaves your machine. There is no server upload step.
- Ready-to-paste HTML. Alongside the PNGs you get the <link> and <link rel="manifest"> tags pre-written, so wiring the icons into your site is a copy-paste job.
- Correct file names. Each size uses the conventional name (favicon-32x32.png, apple-touch-icon.png, android-chrome-192x192.png), which means they drop straight into standard build setups and tutorials.
- Flexible downloads. Grab one size at a time or download the full set in a single click, depending on whether you are patching one device or starting from scratch.
- Transparent-background friendly. PNGs with alpha are preserved, so logos sit cleanly on light or dark browser chrome without an unwanted white box.
Key Features
| Feature | What it does |
|---|---|
| 8 output sizes | Generates 16, 32, 48, 64, 128, 180, 192, and 512px PNGs from one source image |
| Local canvas processing | Resizing happens entirely in your browser via the Canvas API — no upload |
| Individual + bulk download | Save a single size or grab the whole set at once |
| Ready-to-paste HTML snippet | Provides the correct <link rel="icon">, <link rel="apple-touch-icon">, and <link rel="manifest"> tags |
| Transparent-background support | Preserves alpha so logos with transparency render cleanly |
| 10MB upload limit | Accepts source images up to 10MB with a minimum 16x16 resolution |
- The HTML snippet matches the produced file names exactly, so you can drop both the files and the markup into your project root without renaming.
- Because processing is client-side, results appear almost instantly and you can re-run the generator with a new image as many times as you like.
- The 180px output is saved as apple-touch-icon.png, the 192px and 512px outputs follow the android-chrome-* naming used by the standard PWA manifest template.
How to Use the Favicon Generator
- Prepare a source image. Use a square image (ideally 512x512 or larger) with a transparent background for the cleanest results across every output size.
- Open the tool. Go to the Favicon Generator and upload your image via the drop zone or file picker (up to 10MB).
- Preview the outputs. The generator renders each of the eight sizes so you can confirm legibility at 16px and detail at 512px before downloading.
- Copy the HTML snippet. Grab the generated <link> tags and paste them into the <head> of your HTML, then place the manifest reference if you are building a PWA.
- Download the files. Either download individual sizes you need or grab the full set and add them to your site's root directory alongside the manifest.
Understanding Favicon Sizes & Devices
The reason a favicon is actually a set of files is that browsers and operating systems request icons at very different sizes depending on context. A 16px icon looks right in a desktop browser tab but would be blurry on an Android splash screen; a 512px graphic is perfect for that splash screen but wasteful and slow for a tab. Shipping one size for everything means some surface always looks wrong.
The eight sizes this tool produces map to specific platforms:
- 16x16 and 32x32 (favicon-16x16.png, favicon-32x32.png) — the classic browser-tab icons. 16px covers standard tabs; 32px covers high-DPI ("Retina") displays where a 16px file would look soft.
- 48x48 (favicon-48x48.png) — used by Windows for site icons in places like the jump list and shortcut metadata.
- 64x64 (favicon-64x64.png) — commonly used for desktop shortcuts and bookmarks at higher resolutions.
- 128x128 (favicon-128x128.png) — the size Windows expects for store and pinned-site tiles.
- 180x180 (apple-touch-icon.png) — the icon iOS shows when a user adds your site to their home screen. Apple's rounding and gloss are applied on top of this file, so ship a square with padding.
- 192x192 and 512x512 (android-chrome-192x192.png, android-chrome-512x512.png) — the home-screen icon and the splash/launch screen icon referenced by a PWA manifest.
The HTML snippet ties these together:
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png" /> <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png" /> <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png" /> <link rel="manifest" href="/site.webmanifest" />
Browsers read the sizes attribute and pick the best match for the current context, which is why listing every size explicitly is more robust than relying on a single file. The site.webmanifest (which you author separately) is where the 192px and 512px Android icons are declared for installable PWAs.
Practical Use Cases
Launching a new website
A new site needs its tab icon, home-screen icon, and PWA assets wired up before launch. Run your final logo through the generator once, drop the eight PNGs and the HTML snippet into your project, and every surface is covered — from the 16px tab favicon to the 512px splash graphic — without manual resizing in a graphics editor.
PWA and mobile app icon
For an installable progressive web app, the manifest references 192px and 192px/512px icons. The generator produces both with the standard android-chrome-* names, so your manifest's icons array points at files that already exist. The 180px apple-touch-icon.png covers iOS home-screen installation at the same time.
Rebrand or icon refresh
When a logo changes, every deployed size has to be regenerated consistently so that cached old icons don't linger on user devices. Re-running the source image through the generator gives you a clean, identically-named set to replace the old files, keeping your deploy predictable.
Client deliverable handoff
If you hand off branding assets to a client or another team, including a complete favicon set with the matching HTML snippet means they can integrate the icons without guessing at names or sizes. The conventional filenames line up with what most CMS themes and static-site starters expect.
Best Practices
- Start from a large, square source. A 512x512 (or larger) square image gives the downscaler enough information to keep the 16px output legible.
- Keep transparent backgrounds. PNG alpha is preserved, so ship a transparent PNG to avoid a white box on dark browser themes.
- Add internal padding. especially for the 180px Apple touch icon, where iOS applies its own rounding — a logo that fills the frame edge-to-edge gets clipped.
- Test at 16px. If your mark is unreadable at 16px, simplify the source; the tab favicon is the icon users see most often.
- Match the file paths in your snippet. Keep the PNGs and manifest in your site root (or adjust the href values) so the <link> tags resolve correctly.
- Declare the manifest. Even if you are not building a full PWA today, including site.webmanifest future-proofs the setup for Android installation and theme-color metadata.
Start Generating Your Favicons
Stop hand-resizing one image into eight files. Upload a single square source to the Favicon Generator, preview every size, copy the HTML snippet, and download the full set — all processed locally in your browser, with nothing uploaded to a server. Your favicon family will be ready in under a minute.
