What happens when you convert PNG to CUR
- The image is decoded and written as a Windows cursor with its hotspot in the top-left corner.
- Cursors are small: the image is scaled to fit the size you choose, 32 by 32 pixels by default, with the hotspot (the clicking point) at the top-left corner.

Why convert PNG to CUR?
PNG files usually come from screenshots, logos, diagrams and anything with transparency. People convert them to CUR because CUR is the format Windows and web pages use for custom mouse pointers.
In short, PNG is good at what it was made for, and CUR is the more practical choice when the file has to open, upload or print somewhere else. PNG opens in every browser and image viewer, while CUR used by Windows as a mouse pointer; browsers accept it in the CSS cursor property.

Best settings for PNG to CUR
Windows uses 32 by 32 pixel cursors at normal display scaling and 48 or 64 pixels on high-resolution screens. Start from an image with a transparent background, so only the pointer shape shows, and keep the tip of the pointer in the top-left corner, because that is where the hotspot is placed.

About PNG and CUR files
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.
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.
PNG to CUR 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 CUR is always the right way up.
- The file is bigger than expected. It depends on the settings. At the defaults, the CUR usually comes out close in size to the PNG; lower the quality for a smaller file.
Convert PNG to CUR from the command line
If you work in a terminal, ImageMagick converts PNG to CUR in one line:
magick input.png output.curTo convert every PNG in a folder at once, use magick mogrify -format cur *.png. The converter on this page does the same job without installing anything.
