Questions & answers

Frequently asked

Why convert BMP to PNG?

BMP files are uncompressed and can be very large. PNG compresses the same image losslessly, typically achieving 5 to 10 times smaller file sizes while keeping every pixel identical.

Is the conversion lossless?

Yes. PNG is a lossless format so no image data is lost during conversion from BMP.

Is my image uploaded to a server?

Your file or text is processed in your browser and is not uploaded.

Does BMP support transparency?

BMP has limited transparency support. If your BMP has a transparent background, it is preserved in the PNG output.
