Convert one or more BMP images into PNG files. Everything runs securely inside your browser, with no uploads to a server.

This tool converts BMP images into PNG files without uploading anything. BMP stores pixels without any compression, so the files are very large. PNG keeps the same quality in a fraction of the space.
BMP stores pixels without compression. Files are large, but the format is simple and is still used by some older Windows software.
PNG uses lossless compression and supports transparency, which makes it a good fit for logos, screenshots, and graphics with sharp edges.
Drag your files onto the upload area or browse from your device. You can add several images at once.
PNG keeps the full detail of your image, so there is nothing to adjust unless transparency needs a background colour.
Start the conversion. Everything happens on your own device, so the speed depends on your computer rather than your internet connection.
Save each image on its own, or download everything together as a ZIP file.
Most online converters send your file to a server, convert it there, and send it back. This one does not. The conversion runs inside your browser, so your BMP images never leave your computer or phone. There is nothing to delete afterwards, because nothing was stored in the first place.
This also means the tool keeps working on a slow connection, and it can handle private documents, scanned paperwork, and personal photos without you having to trust a third party with them.
Add one or more BMP images, choose your output settings, and start the conversion. Your PNG files are created inside your browser and are ready to download straight away.
