How to convert BMP to PNG
- Drop your BMP files in the box above. You can also click the box to pick files, or paste them.
- Each file is converted to PNG on your own device. It usually takes a second or two.
- Download each file, or get them all in one zip. Every file keeps its name.
Why convert BMP to PNG?
BMP files are enormous for what they hold. PNG keeps every pixel and takes a fraction of the room.
PNG files are usually a little smaller than BMP.
About the two formats
BMP: A plain Windows format with no compression. Files are big, but even very old programs can open them.
PNG: Keeps every detail sharp and supports transparent backgrounds. Works everywhere. The safe pick for logos, graphics and screenshots.
The whole conversion happens in your browser. Your file is unpacked into raw pixels and saved again as PNG. Nothing is sent to any server.
Common questions
Is the BMP to PNG converter free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The BMP to PNG converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Is anything lost converting BMP to PNG?
Nothing. BMP normally stores pixels with no compression at all and PNG compresses them without discarding any, so the picture is identical and the file is very much smaller. There's no reason to keep an ordinary BMP once you have the PNG.
Does converting BMP to PNG lose quality?
No. Both BMP and PNG store every pixel exactly as it was, so the picture that comes out is identical to the one that went in. Only the file size and what can open the file change.
Will the PNG file be smaller than the BMP?
Usually a bit smaller, though the gap isn't dramatic. The exact saving depends on the picture. If size is the whole reason you're here, the compress tool will hit a number you name instead of leaving it to chance.
