Convert BMP to PNG
BMP files are usually stored without compression, so they're huge. PNG keeps the image pixel for pixel while making the file far smaller.
How to convert BMP to PNG
- 1Click “Choose images” or drop your BMP files onto the page.
- 2Check the files in the list.
- 3Click “Convert” and download your PNG images, one by one or as a ZIP.
Same image, smaller file
PNG compression is lossless: the image looks exactly like the BMP, often at a tenth of the size or less for screenshots and graphics.
Where BMPs come from
Old Windows software, scanners and some embedded devices still save BMP. PNG works in every browser, editor and document.
Many at once, privately
Convert up to 50 images in one go and download them together as a ZIP. Everything happens in your browser, and location data and other metadata are left out of the new files.
