ICON to TIFF Converter
FileFlip converts ICON to TIFF entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an ICON file to TIFF?#
- Drop your ICON file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to TIFF and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the TIFF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting ICON to TIFF lose quality?#
No. Converting ICON to TIFF writes the data out again without discarding any of it, so nothing that was in the ICON file is lost on the way. What changes is the size of the file, not what is inside it.
Is it safe to convert ICON files online?#
Yes, because nothing is uploaded. FileFlip converts ICON files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What ICON to TIFF actually does to the file#
Converting ICON to TIFF runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, writes the data out again without discarding any of it, keeps transparency, and drops extra images.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: ICON → TIFF |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossless |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Transparency | Kept | Carried through into the converted file. |
| Extra images | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- ImageMagick is asked for a single image, so only the first frame, page, or icon size is read
What is an ICON file?#
ICON is ImageMagick's alternate name for the ICO format, the container Windows uses for small multi-resolution images shown as application, file and shortcut icons, so a file written as ICON is the same Windows icon container as one written as ICO.
Use ICON, or the equivalent ICO, for Windows application icons, favicons and shortcut images, where the file needs to offer several sizes in one container.
Convert to PNG when a single-resolution image is needed for general use, since most software outside Windows icon contexts doesn't expect an ICO/ICON container.
What is a TIFF file?#
A TIFF file stores one or more raster images, usually uncompressed or losslessly compressed, inside a tagged container that scanners, printers, and publishing software rely on to keep exact pixel data intact through repeated edits.
Use TIFF for scanned documents, print production, and archival photography, where preserving every pixel losslessly matters more than file size.
Convert TIFF to JPEG or PNG when the image needs to go on the web or be shared casually, since browsers cannot display TIFF and the files are far bigger than screen viewing requires.
ICON to TIFF questions people ask#
What is the difference between ICON and ICO?
There isn't one. ICON is ImageMagick's alternate name for its ICO coder, so a file written as ICON is the same Windows icon container as one written as ICO.
Why does ImageMagick have both ICO and ICON as format names?
ImageMagick registers ICON alongside ICO purely as a naming convenience, since some tools and scripts refer to Windows icon files by either name. Both write the same icon container.
What can an ICON/ICO file store?
An ICO/ICON file can store several versions of the same image at different sizes and color depths in one container, which is how Windows shows the right icon size for a desktop shortcut, a taskbar button, or a file listing.
What is a TIFF file used for?
TIFF files are used for scanned documents, professional photography, and print production, because the format can store an image with no compression loss at all. Publishing software, print shops, and archives favor it precisely because a TIFF looks identical no matter how many times it is opened and resaved.
