Format Details
MSP
MSP is the proprietary bitmap image format used by Microsoft Paint in the early Windows 1.x and 2.x era. It stores only monochrome (black and white) images in a simple uncompressed binary format without any metadata or color information. MSP is a historical format not supported by modern applications, but files can be converted to preserve content from very old PC collections.
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 MSP to ICO: what actually changes
MSP 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 .MSP and .ICO each hold
.MSP 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.
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 .MSP using the same tool.
Tips for a clean MSP to ICO conversion
Start from the original file
Convert the .MSP 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/x-msp 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 .MSP 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.
