About this converter
BMP is an uncompressed Windows bitmap format producing very large files, still common in legacy software. PNG is a lossless format with transparency support, ideal for logos, screenshots and graphics with sharp edges.
BMP files are uncompressed, which is why they are enormous — a photograph can run to tens of megabytes. Converting BMP to PNG usually happens because something old produced the file and everything modern is choking on its size.
Frequently asked questions
Will converting to PNG reduce the image quality?
No — PNG keeps every detail exactly as it was.
Do my BMP files get sent anywhere?
No. Everything happens on your own device, so your pictures never leave it.
