PNG image
A lossless raster format with full alpha transparency support.
Best for screenshots, interface assets, logos, and transparent graphics.
BMP has no transparency, so transparent areas are filled with a solid background. Add your files, convert them in one batch, and download each BMP directly.
The converter runs in your browser and an isolated processing queue. Nothing to install, and every upload is scanned for malware before it is processed.

PNG to BMP
What changes in the file, and what to check before you share the result.
PNG can hold transparent areas, but BMP cannot. Transparent pixels are filled with a solid background, so logos and cut-outs will sit on a box. Keep the PNG if you need the transparency.
BMP is usually stored without compression, so the result is much larger than the source. Use it when a program specifically asks for BMP.
Open the converter settings to set an output width and quality for every BMP in the batch. Leave the width empty to keep the original dimensions.
PNG files are lossless and often contain transparency, which matters for logos and screenshots.
Short answers about limits, privacy, and keeping the converted file.
No. BMP has no alpha channel, so transparent areas are filled with a solid color. Convert to PNG or WebP instead if you need to keep transparency.
