Frequently asked questions
Is this TIFF 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 TIFF to ICO?+
Drop your TIFF 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.

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.

About TIFF files+
TIFF is a flexible, high-fidelity format favored in printing, scanning, and professional photography workflows.
TIFF (Tagged Image File Format) was designed to be a container flexible enough for almost any kind of image data — multiple pages, layers, high bit depths, and either lossless compression or none at all. That flexibility is exactly why it became the standard in print production and document scanning, where color accuracy and detail matter more than file size. It's rarely seen on the web, since browsers don't render it natively and its files run large, but it remains the safe choice whenever an image needs to survive a professional print or archival pipeline untouched.
How to open a TIFF file
Opens readily in Windows Photos, macOS Preview. For real editing, use Adobe Photoshop, GIMP, Adobe Lightroom.
Most web browsers won't display TIFF directly — convert to JPG or PNG first if you need it to show up on a page.
Good for
- supports lossless compression and very high bit depths
- the de facto standard in print and scanning pipelines
Watch out for
- large files
- poor support in web browsers
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
- not meant for anything beyond small icons
