BMP to PNG Converter

Convert BMP and DIB bitmap images to PNG locally in your browser.

About this tool

BMP is still found in legacy Windows software, archival assets, old screenshots, and bitmap artwork, but the files are often large and inconvenient for modern web workflows. PixWarp decodes BMP in your browser and exports a standard PNG without uploading your image.

How to use

01
Drop one or more .bmp or .dib images into the upload area.
02
PixWarp decodes each bitmap locally.
03
Preview the PNG output and file size.
04
Download the converted PNG files.

Privacy

Processing happens in your browser whenever the tool can run locally. Your source files are not uploaded to PixWarp servers.

Output details

• Outputs standard image/png files.
• PNG keeps bitmap pixels lossless while being easier to use in modern tools.
• Very large BMP files may take longer because they can store uncompressed pixels.
