In your photos in BMP format if you zoom into certain areas you´ll see that you lose quite a lot of quality in comparison with the original, and this is where you need a tool called MyBitmap 1.0.
There are two objectives of MyBitmap 1.0. On the one hand to graphically optimize the zoom zone to get better clarity and quality, and on the other reduce the wight of the original BMP so as to take up less space and be more manageable.
An interesting tool without doubt, and above all practical for users who often work with BMP files.
