Generates one .ico file containing 16×16, 32×32, 48×48, 64×64, 128×128 and 256×256 versions of your image.
About This Tool
An .ico file isn’t just one icon — it can hold several resolutions of
the same image bundled into a single file, so the right size gets
used automatically wherever it’s needed. This tool converts any
image into a proper multi-resolution .ico, entirely in your browser.
It’s the file format classic favicons use, and it’s also what
Windows desktop applications use for their app icons.
Key Features
Instant Generation
No upload step and no button to click — your .ico file is built
the moment you add an image.
Private & Secure
Your image never leaves your device — nothing is ever uploaded to a server.
Multiple Resolutions, One File
16, 32, 48, 64, 128, and 256px versions are all embedded inside a single .ico.
Simple, Single-File Output
Just one .ico file — no ZIP to unpack, no manifest, no extra code required.
Works Everywhere
Compatible with desktop, tablet, and mobile browsers — no app to install.
Completely Free
No subscriptions, registrations, sign-ups, or hidden limits.
How It Works
Upload Your Image
A simple, bold square image works best — busy artwork won’t read clearly at the smallest embedded size.
The .ico Generates Automatically
No button to press — every embedded resolution is built the moment your image is added.
Download the File
Save the finished .ico file straight to your device.
Use It
Rename it to favicon.ico and place it in your site’s root folder, or set it as a desktop app’s icon.

Frequently Asked Questions
Is this tool free to use?
Yes, completely free, with no sign-up required.
Is my image uploaded to a server?
No. The .ico file is generated locally in your own browser and your original image never leaves your device.
What’s the difference between this and the Favicon Generator?
This tool creates just one .ico file with several sizes bundled
inside — enough for a classic favicon.ico or an app icon. The
Favicon Generator produces a full modern set (PNG icons for
Android/iOS home screens, a web manifest, and a ready-to-paste
HTML snippet) for sites that also target mobile and installable
web apps. If you just need a favicon.ico, this tool is simpler;
if you want full mobile/PWA support too, use the Favicon
Generator instead.
Do I need to add any code to use this?
Not necessarily — browsers automatically look for a file named
favicon.ico at your site’s root. For extra certainty, you can
also add <link rel="icon" href="/favicon.ico">
to your page’s <head>.
Does my image need to be square?
It doesn’t have to be — non-square images are automatically center-cropped to a square first.
Can I use this as a desktop app icon?
Yes — .ico is also the standard format Windows applications use for their icons.
