Frequently Asked Questions

What is a 4-bit image?

4 bits per pixel = 16 possible colors, selected from a palette stored in the file header. This was the standard for early Windows (3.x) graphics. Modern images use 24-bit (16.7 million colors).

Can modern tools open 4-bit BMP?

Yes. All image viewers and libraries handle 4-bit BMP correctly — it's part of the BMP spec. Test it to ensure your tool doesn't assume all BMPs are 24-bit.
