Question 1

Does rotation affect BMP quality?

Accepted Answer

90°, 180°, and 270° rotations are pixel-perfect with no quality loss. Custom angles require resampling with minimal quality impact.

Question 2

Can I compress while rotating?

Accepted Answer

Yes. Under "Image Compression," choose any method. Since BMP is uncompressed, even moderate compression produces significantly smaller files.

Question 3

Can I also resize while rotating?

Accepted Answer

Yes. Under "Image resolution," set by percentage or keep original. Useful for reducing large BMP screenshots.

Question 4

Should I rotate as BMP or convert to PNG?

Accepted Answer

For modern use, BMP to PNG gives lossless compression at much smaller file sizes. Keep BMP only for legacy Windows applications that require it.

Question 5

Why are BMP files so large?

Accepted Answer

BMP stores raw pixel data with no compression. A 1920×1080 image at 24-bit color is about 6 MB as BMP vs ~1 MB as PNG (lossless) or ~200 KB as JPEG.
