Turn any image into crisp favicon and app-icon PNGs at every size you need, bundled into one ZIP. Everything runs in your browser — your image never leaves your device.
Add one or many — PNG, JPG & WebP. Or paste with ⌘/Ctrl + V
Load your logo into PixKit's Favicon tool, tick the sizes you need — 16, 32, 48, 180 and 512 pixels — pick a transparent, white or ink background, and click Export favicon .zip. PixKit center-crops your image square, renders each PNG in your browser, and downloads them together. Nothing is uploaded.
Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.
Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.
Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.
Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.
Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.
From logo to a ZIP of production-ready icons, all in your browser.
Drag in, paste, or pick the image. Square images map 1:1; anything else is center-cropped to the largest square automatically.
Toggle the 16², 32², 48², 180² and 512² size chips, and choose transparent, white or ink to fill behind any see-through areas.
Click the export button — each size renders locally with high-quality smoothing and downloads as one ZIP: favicon-16.png, favicon-32.png and so on.
The 16, 32 and 48 px PNGs cover browser tabs, bookmarks and desktop shortcuts — link them with a simple rel="icon" tag.
The 512 px PNG is the large icon your web-app manifest points at for installs and splash screens; browsers derive smaller sizes from it.
Export the 180 px size as your apple-touch-icon so "Add to Home Screen" shows a crisp tile instead of a blurry screenshot.
Extension manifests want 16, 32, 48 and 128-class icons — generate the standard sizes in one pass instead of resizing by hand.
Unannounced logos never touch a server. Generate the full icon set locally and the design stays secret until launch day.
Everything you need to know about making favicons in PixKit.
A favicon is the tiny square icon that shows in browser tabs, bookmarks and phone home screens. PixKit turns any photo, logo or graphic into a complete set of favicon and app-icon PNGs — 16, 32, 48, 180 and 512 pixels — entirely inside your browser. There is no upload, no queue and no account, which makes it safe for unreleased logos and client work.
Tick the size chips you want and PixKit center-crops your image into perfect squares for each one. 16 and 32 px cover classic browser tabs, 48 px is used by some browsers and Windows shortcuts, 180 px is Apple's touch icon for iOS home screens, and 512 px is the large icon a web-app manifest references — browsers scale it down for anything in between.
Icons with transparency can look wrong on some surfaces, so PixKit lets you choose the fill behind your image: keep it transparent, or flatten onto white or a dark ink background before export. Each rendered size uses high-quality smoothing, so even the 16 px icon stays as sharp as it can be.
Hit Export favicon .zip and every selected size is rendered and bundled as favicon-16.png, favicon-32.png and so on — ready to drop straight into your project and reference from your HTML and manifest. The ZIP module needs the served app (it loads as an ES module), so use pixkit.com or your local server rather than a file:// page.
