Favicon Generator
Turn a logo into every icon a website needs: favicon.ico for browser tabs, an Apple touch icon, Android and web app icons and a web manifest, with the HTML to paste into your page.

You can also paste an image with Ctrl+V (⌘V on a Mac).
Your images stay on your device. Nothing is uploaded.
How to make a favicon
- Choose or drop your logo. A square PNG or SVG works best.
- Adjust the background, shape and padding while watching the preview in a browser tab.
- Download the ZIP, upload its files to your site’s root folder and paste the HTML into your page’s <head>.
Private by design
Most online image tools upload your pictures to their servers. This one doesn’t: Favicon Generator runs entirely in your browser, so family photos, IDs, screenshots and client work never leave your device. It’s free, with no watermark and no limit on how many images you process, and you don’t need an account.
Questions
Which files are in the package?
favicon.ico (16, 32 and 48 pixels), favicon.svg if you started from an SVG, apple-touch-icon.png (180 pixels), icon-192.png and icon-512.png for Android and installable web apps, and site.webmanifest.
What size should my logo be?
At least 512 × 512 pixels, and square. An SVG is ideal because it's sharp at every size. Detailed logos can blur at 16 pixels, so a simplified mark often works better as a favicon.
Why does the Apple icon have a background?
iPhones and iPads fill transparent parts of home-screen icons with black, so the Apple icon always gets a solid background: white, unless you choose a colour.
Are my images uploaded?
No. Every tool runs in your web browser, so your images are read, changed and saved on your own device and never sent to LabAnvil or anyone else. Once the page has loaded, the tools even work offline.
Is it free? Do I need an account?
Free, with no watermark, no daily limit, no account and no cap on file size beyond what your device's memory can handle.
