Why are BMP files so large?

BMP files are typically uncompressed, storing raw pixel data. A 1920x1080 BMP can be 6MB, while the same image as JPG might be only 200KB.

Will I lose quality when compressing BMP?

Converting to PNG preserves original quality losslessly. Converting to JPG or WebP uses compression but maintains excellent visual quality at much smaller file sizes.

What's the best format to convert BMP to?

Use JPG for photos, PNG for graphics with transparency, and WebP for the best compression with modern browser support.

Can I batch convert multiple BMP files?

Yes, you can upload and convert multiple BMP files simultaneously for efficient batch processing.
