About ICO files
ICO files hold one or more small images for Windows programs and website favicons, often in several sizes.
Open Online shows the image your browser picks from the file, with zoom for small details.
What you can do here
- Zoom with the mouse wheel or buttons, drag to pan
- Switch between fit to screen and actual pixels
- Transparent areas shown on a checkerboard
- Rotate or flip, and save the result as a new file
- Read camera data (EXIF): camera, lens, exposure, date and GPS position
Limitations
- Saving a rotated or flipped copy re-encodes the image and drops its EXIF data.
Privacy
The file is read by your browser and stays on your device. Open Online has no server that could receive it, and nothing is stored once you close the tab. Privacy policy

Yes, aintob.com converts ICO to PNG.
