Frequently Asked Questions
Why convert PNG to BMP?
Some older programs, scanners, and embedded systems only accept plain BMP bitmaps. Converting gives you a file those tools can open.
What happens to transparency?
BMP in this tool has no alpha channel, so transparent areas are placed on a white background before saving.
Why is the BMP so much larger?
BMP stores every pixel without compression, so the file is usually much bigger than the PNG. The tool shows both sizes.
Is my image uploaded anywhere?
No. The conversion runs entirely in your browser, so the file never leaves your computer and it works offline.
Does it keep the same dimensions?
Yes. The pixel width and height stay identical; only the format changes.
Does it work on a phone or tablet?
Yes, in any modern browser, with nothing to install.
