Convert BMP files to PNG in seconds. PNG shrinks a BMP a lot without losing any detail.
Drop one or more BMP files onto the page, or choose them from your device.
BMP has no transparency, so the picture stays solid. PNG does not discard any detail, so there is no quality setting. The file can be larger than the BMP.
Press Convert, then download each PNG file, or all of them as a ZIP.
BMP (BMP image). BMP is the simple bitmap format of Windows. It stores raw pixels with no compression, so the files are large, but almost any program can read them. It is best for older software and programs that only accept plain bitmaps.
PNG (PNG image). PNG keeps every pixel exactly as it is and supports transparent backgrounds. The files are larger than JPG for photos, but text, logos and screenshots stay perfectly sharp. It is best for logos, screenshots, graphics and pictures that need a transparent background.
Add your BMP file, check that the target is PNG, and press Convert. Then download the PNG file. It takes a few seconds.
