MRW
MRW is the camera RAW format of Konica Minolta digital cameras. It stores unprocessed sensor data for later adjustment. These cameras are no longer made and app support is limited, so MRW files are often converted to JPG, PNG, or TIFF.

ICO
ICO is the icon format of Microsoft Windows. A single ICO file can hold several images in different sizes, such as 16x16, 32x32, and 256x256 pixels. ICO files are used for application icons and website favicons.
What happens when MRW becomes ICO
Source format

Target format
ICO is the image source or target format for this conversion path.
What changes
The MRW pixels are decoded and written using ICO compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when ICO supports them.
- Codec and quality implications
- Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Conversion steps
- Upload a MRW file no larger than 1 GB.
- Confirm that ICO is selected as the target.
- Download the ICO file and check the result before deleting your source.
Troubleshooting
- The MRW file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The ICO file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- Transparency, color, or animation changed.
- Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
