Frequently asked questions
Is this GIF to ICO converter really free?+
Yes. There's no file limit, no watermark, and no account required. Because the conversion runs in your browser instead of on a server, there's no processing queue to pay for.
Is my file uploaded anywhere?+
No. Orbfile decodes and re-encodes the image locally using ImageMagick compiled to WebAssembly, running entirely inside your browser tab. The bytes never leave your device.
Will converting to ICO lose quality?+
There's a quality slider so you can balance file size against visual quality. At high quality settings the difference is usually invisible.
Can I convert more than one file at once?+
Yes — drop as many files as you like and download them individually or as a single ZIP.
Is there a maximum file size?+
There's no fixed upload limit — Orbfile isn't uploading anything. The practical ceiling is your device's own memory, which comfortably handles even large, high-resolution photos.
How do I convert GIF to ICO?+
Drop your GIF file into the box above — it's automatically converted to ICO and a download link appears in seconds. No settings are required, though you can adjust quality if the tool offers a slider.
About GIF and ICO
What is GIF?
GIF is a decades-old format limited to 256 colors per frame, but it's still the standard way to share short looping animations.
Full GIF format guide →What is ICO?
ICO is the Windows icon container format — it can bundle several sizes of the same image into one file for favicons and app icons.
Full ICO format guide →The short version: ICO gives you multi-resolution support in a single file, which helps once you run into GIF's biggest limitation: only 256 colors, so photos look banded. It's a natural move when your image is headed toward website favicons.
How it works
- 1
Drop your file in
Drag your image onto the box above, or click it to browse — there's no account to create and no upload to wait on.
- 2
Pick your settings
The output format is already set for this page — just adjust any extra options shown, if there are any.
- 3
Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your image is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- Website favicons
- Windows application icons
- Preparing images for a website or online store
- Attaching a photo to an email with a size limit

About GIF files+
GIF is a decades-old format limited to 256 colors per frame, but it's still the standard way to share short looping animations.
GIF (Graphics Interchange Format) predates the web itself — CompuServe introduced it in 1987 as a compact way to share images over slow dial-up connections. Its defining limitation, a palette of at most 256 colors per frame, made it a poor fit for photos even by the standards of the time, but its lossless compression and built-in support for multi-frame animation gave it a second life as the format behind reaction GIFs, memes, and short looping clips — a role modern formats like WebP and AVIF have struggled to fully displace, mostly because GIF support is so deeply baked into every platform.

About ICO files+
ICO is the Windows icon container format — it can bundle several sizes of the same image into one file for favicons and app icons.
ICO was built for exactly one job: giving Windows a single file that holds several resolutions and color depths of the same icon, so the operating system can pick whichever version fits — a small taskbar icon versus a large desktop shortcut, for instance — without any scaling. That same trick is why browsers still expect a site's favicon.ico to work the same way: one file, several embedded sizes, used at whatever resolution the browser tab needs.
How to open a ICO file
Opens readily in Windows Explorer previews it automatically, Any web browser. For real editing, use GIMP, IcoFX, Photoshop (with a plugin).
Good for
- multi-resolution support in a single file
- the format browsers expect for favicon.ico
Watch out for
