Why convert CUR to PNG?
CUR files usually come from custom mouse pointers for Windows and for websites. People convert them to PNG because PNG keeps sharp edges, text and transparency without any loss.
In short, CUR is good at what it was made for, and PNG is the more practical choice when the file has to open, upload or print somewhere else. CUR used by Windows as a mouse pointer; browsers accept it in the CSS cursor property, while PNG opens in every browser and image viewer.

About CUR and PNG files
What is a CUR file?
A CUR file is built like an ICO icon, with one addition: a hotspot, the exact pixel that does the clicking. Windows reads cursors from CUR files, and web pages can use them through the CSS cursor property.
What is a PNG file?
PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.
CUR to PNG not working? Common problems
- Colours look slightly different. Browsers convert images to the standard sRGB colour space when they decode them, so wide-gamut and CMYK images can shift a little.
- A phone photo comes out upright even though it looked sideways elsewhere. That is correct: the rotation stored in the photo is applied during conversion, so the PNG is always the right way up.
- The file is bigger than expected. It depends on the settings. At the defaults, the PNG usually comes out close in size to the CUR; lower the quality for a smaller file.
Convert CUR to PNG from the command line
If you work in a terminal, ImageMagick converts CUR to PNG in one line:
magick input.cur output.pngTo convert every CUR in a folder at once, use magick mogrify -format png *.cur. The converter on this page does the same job without installing anything.
