Frequently Asked Questions
Why is the BMP file so much larger than my original?▾
BMP stores every pixel uncompressed, so BMP files are typically far larger than a JPG, PNG, or WEBP of the same image — this is expected and inherent to the format.
Will transparency be preserved?▾
No — this tool produces a standard 24-bit BMP without an alpha channel, so any transparency in the source becomes solid.
