Convert BMP to PNG Online

This page opens the image converter with PNG already selected as the output format — just drop a BMP file and download the result. BMP is an uncompressed legacy Windows format — maximum compatibility with old software, but enormous file sizes. PNG is a lossless format with full transparency support — the standard for logos, screenshots and graphics.

Converting to PNG makes sense when you need lossless quality or transparency support: logos, screenshots, graphics with text, or any image that will be edited again later.

Drop or pick the file, press the button and save the result. Nothing is uploaded anywhere — the conversion happens locally in your browser, so private images stay private. Need the opposite direction or a different format? Open the full converter.
