How do I make a favicon from an image for free?

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.

A private image toolkit, not just a watermark remover

Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.

Lossless watermark removal

Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.

Crop & resize

Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.

Convert & compress

Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.

100% private

Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.

Export a favicon set in 3 steps

From logo to a ZIP of production-ready icons, all in your browser.

Load your logo

Drag in, paste, or pick the image. Square images map 1:1; anything else is center-cropped to the largest square automatically.

Pick sizes and a background

Toggle the 16², 32², 48², 180² and 512² size chips, and choose transparent, white or ink to fill behind any see-through areas.

Export favicon .zip

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.

What people generate icons for

Website favicons

The 16, 32 and 48 px PNGs cover browser tabs, bookmarks and desktop shortcuts — link them with a simple rel="icon" tag.

PWA and Android icons

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.

iOS home-screen icons

Export the 180 px size as your apple-touch-icon so "Add to Home Screen" shows a crisp tile instead of a blurry screenshot.

Browser extensions

Extension manifests want 16, 32, 48 and 128-class icons — generate the standard sizes in one pass instead of resizing by hand.

Confidential rebrands

Unannounced logos never touch a server. Generate the full icon set locally and the design stays secret until launch day.

Frequently asked questions

Everything you need to know about making favicons in PixKit.

Does my logo leave my browser when generating favicons?+
No. Every size is rendered 100% locally on a canvas in your browser and zipped on your device. Nothing is sent anywhere, so it's safe for logos and unreleased designs.
Which favicon sizes should I use?+
For most sites, 16, 32 and 48 px cover browser tabs and shortcuts, 180 px is the Apple touch icon for iOS, and 512 px is the large icon referenced in a web app manifest — browsers scale it down for the sizes in between.
What files are inside the favicon ZIP?+
One PNG per selected size, named favicon-16.png, favicon-32.png, favicon-48.png, favicon-180.png and favicon-512.png, in a ZIP named after your image. Untick any chip to leave that size out.
Why does the ZIP download need the served app?+
The ZIP packer (JSZip) ships with PixKit but loads as an ES module, which browsers block on plain file:// pages. Use pixkit.com or run start.command to serve the app locally and the export works — offline included, once loaded.
Can I put a solid background behind a transparent logo?+
Yes. Pick the white or ink (dark navy) swatch and every exported size is flattened onto that color; choose the checkered swatch to keep full transparency instead.
Do I get a .ico file?+
PixKit exports modern PNG icons, which all current browsers support via the link rel="icon" tag. PNG favicons are sharper and simpler than legacy multi-resolution .ico files.
How is my image fitted into a square?+
PixKit takes the largest centered square from your image (a cover crop) and scales it to each size with high-quality smoothing, so non-square images stay centered and undistorted.

Generate favicons and app icons without uploading anything

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.

All the standard sizes

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.

Backgrounds for transparent logos

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.

One ZIP, ready to ship

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.
