PNG is the better everyday format — smaller, lossless, and transparent — so converting away from it only makes sense when the destination insists on BMP. This free png to bmp converter is for exactly that case: legacy Windows software, game modding tools, and industrial systems that only accept a bitmap. Every pixel survives, because both formats are lossless, but there is one change to expect: this tool writes a 24-bit BMP, which has no alpha channel, so transparent areas become white. Everything runs in your browser, so nothing is uploaded and no signup is needed.
How to use this png to bmp converter
Three quick steps — no signup, no cost.
Choose one.png file. It is decoded in your browser, never uploaded to a server.
If your PNG has see-through parts, preview them: they will come out white in the BMP, because 24-bit BMP has no transparency.
Save the uncompressed.bmp and use it wherever a bitmap is required.
When a png to bmp converter beats keeping the PNG
Only when the destination demands BMP — then it does the job without losing a pixel.
Older Windows imaging tools, modding utilities, and embedded panels that read only BMP can finally open your picture.
The BMP is a plain grid of RGB values, so the receiving program reads it directly with no decompressor in the way.
Once stored uncompressed, the image can be opened and saved repeatedly without any new compression damage.
Transparent PNG areas become white in a 24-bit BMP. If transparency matters to you, keep the PNG — this page says so before you convert.
PNG to BMP Converter FAQs
Short, direct answers to the questions readers ask most.
No. This tool writes a 24-bit BMP, which has no alpha channel, so transparent and semi-transparent areas become white. If you need transparency, keep the PNG.
No, apart from the transparency flattening above. Both formats store pixels losslessly, so the visible picture is pixel-identical.
PNG compresses its pixels losslessly; BMP stores them raw and uncompressed. The same picture therefore takes far more disk space as a BMP.
Paint, Photoshop, GIMP, IrfanView, and virtually every Windows application that handles images.
Yes. It converts in your browser with no account, no signup, and no watermark.
