Favicon Generator

How this favicon generator works

Everything happens on an HTML canvas inside your browser. You give the tool a source — an uploaded PNG, JPG, WebP, or SVG, a single emoji, or one to three letters — and it draws that source onto a square tile with your chosen background, shape, and padding.

The tile is then redrawn at every standard favicon size with high-quality image smoothing: 16, 32, and 48 pixels for browser tabs, 180 for the iOS home screen, and 192 plus 512 for Android and installable PWAs. Each size is encoded as a PNG with the canvas toBlob method.

The classic favicon.ico is assembled byte by byte in pure JavaScript. The writer builds a six-byte ICONDIR header, a sixteen-byte directory entry for each embedded 16, 32, and 48 pixel image, then appends the PNG payloads. Browsers and Windows both accept PNG data inside an .ico, so the file stays small and crisp.

What a complete favicon pack includes

A favicon is not one file anymore — it is a small set that covers tabs, bookmarks, home-screen shortcuts, and installable apps. Shipping only a single favicon.ico leaves blurry icons on phones and blank tiles in PWA installers. This generator outputs the full set in one click.

• favicon.ico — a multi-size icon (16/32/48) served from your site root. It is the universal fallback every browser and crawler still requests from /favicon.ico.
• favicon-16x16.png and favicon-32x32.png — the sharp PNG tab icons modern browsers prefer when you reference them in link tags.
• apple-touch-icon.png — the 180×180 icon iOS uses when someone adds your site to their home screen.
• android-chrome-192x192.png and 512x512.png — the icons named by your web manifest for Android and Progressive Web App installs.
• site.webmanifest — a minimal manifest that points at the PWA icons and sets a theme color, ready to drop in beside the images.

Why and when to use a favicon generator

Reach for a favicon generator any time you launch a site, rebrand, or ship a quick landing page and need a correct icon set fast. Hand-exporting six PNGs and hand-writing an .ico is fiddly and easy to get wrong, and a missing apple-touch-icon is one of the most common launch-day oversights.

A clear favicon also does real work in a crowded browser. People keep dozens of tabs open, and a recognizable icon is how they find your tab again. The same icon shows up in bookmarks, history, and search results, so a sharp, on-brand mark quietly reinforces trust everywhere your URL appears.

For the source, a square image of at least 512 pixels gives the best results because every smaller size is downscaled from it. Bold, simple shapes read well at 16 pixels; detailed logos with thin lines or small text usually do not, so a simplified glyph or monogram is often the stronger favicon.

Cost reality: free here, AI imagery in the app

This favicon generator is completely free with no usage limit because it does no server work. The canvas draw, the PNG encode, the .ico assembly, and the ZIP packaging all run locally, so there is nothing to meter and nothing to charge for.

When you need the artwork itself — a logo mark, an icon illustration, or a brand glyph to feed into this tool — that creative work runs on paid models inside the Playcut studio. You can render a square brand symbol with the Playcut AI image generator, export it as a PNG, then drop it into the generator above to ship the full pack.

Playcut plans start at Hobby $9/mo (500 credits), then Pro $29/mo (2,000 credits), Studio $79/mo (6,000 credits, 4 seats), and Agency $149/seat/mo (10,000 credits per seat). Credit packs that never expire are also available: 600 credits for $9, 2,500 for $35, and 5,000 for $65. Pricing as of May 2026.

Favicon generator FAQ

Is this favicon generator really free and private?

Yes. The favicon generator runs entirely in your browser using the Canvas API and a pure-JavaScript .ico writer. Your image, emoji, or text and every file the tool produces never leave your device — there is no upload, no account, and no watermark. You can generate as many favicon packs as you want at no cost.

What favicon sizes do I actually need in 2026?

A modern site needs a small handful: a multi-size favicon.ico (16, 32, and 48 pixels) for legacy browsers and Windows, a 180×180 apple-touch-icon.png for iOS home screens, and 192×192 plus 512×512 PNGs for Android and installable PWAs. This tool emits all of them, so you do not have to remember the list.

Why ship a favicon.ico when PNG favicons exist?

The .ico file is the safe default that every browser, search engine crawler, and old Windows shortcut still requests from /favicon.ico. Modern browsers read PNG icons from your link tags, but a multi-size .ico is the fallback that prevents a broken-icon request in logs. The generator builds a valid multi-image .ico so you keep that fallback.

Can I make a favicon from an emoji or just text?

Yes. Pick the Emoji tab and type any emoji, or pick the Text tab and enter one to three letters on a colored tile. Both modes draw onto the same canvas pipeline and export the full pack — .ico, apple-touch-icon, manifest icons, and the link snippet — so a quick monogram favicon takes seconds with no design file.

How do I install the favicon on my website?

Unzip the pack into your site root so favicon.ico sits at /favicon.ico, then paste the generated <link> snippet into the <head> of every page and ship site.webmanifest alongside the PNGs. Browsers cache favicons aggressively, so a hard refresh or a cache-busting query string helps you see the new icon right away.
