Format Details
TIFF
TIFF (Tagged Image File Format) is a flexible, high-quality raster image format widely used in professional photography, desktop publishing, scanning, and archival imaging. It supports lossless compression, multiple color spaces (RGB, CMYK, LAB), multi-page documents, and can embed multiple images within a single file. TIFF is the standard format for scanned documents, medical imaging, and any workflow that demands the highest possible image fidelity.
imageICO
ICO is the Windows icon file format used to display icons for applications, files, folders, and shortcuts in the operating system. It can contain multiple image sizes and color depths within a single file, ensuring icons look sharp at different display scales and DPI settings. ICO files are also used as website favicons — the small icon displayed in browser tabs, bookmarks, and address bars.
imageConverting TIFF to ICO: what actually changes
TIFF to ICO is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .TIFF and .ICO each hold
.TIFF is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .ICO is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .ICO encodes pixels, dimensions and colour depth — not what the file is about.
Quality and file size
Both .TIFF and .ICO are lossless, so the content itself survives the trip intact. The main difference is how efficiently each format packages pixels, dimensions and colour depth — which is what changes the file size.
When this conversion is the right one
Reach for .ICO when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .ICO to .TIFF using the same tool.
Tips for a clean TIFF to ICO conversion
Start from the original file
Convert the .TIFF you started with, not an earlier .ICO output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Image/tiff becomes image/x-icon. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Watch transparency and animation
If the .TIFF has a transparent background or animation, confirm .ICO supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
