FAQ

Is there any quality loss?
No. PNG uses lossless compression, so quality is fully preserved.
Are images sent to a server?
No, all processing happens in your browser.
Is there a file size limit?
Up to 50MB per file is supported. Files exceeding this will result in an error.
Can multiple files be converted at once?
Yes. Drop multiple BMP files together and they will be converted and downloaded one by one.
Can transparency be added to the converted PNG?
This tool converts BMP to PNG as-is. Transparency is not added. If the original BMP has no transparency information, the result will be opaque.
