Upload a BMP image and download it as a PNG — much smaller, with the same lossless quality.
BMP files are uncompressed and often huge. PNG compresses losslessly, often shrinking the file by 70% or more with zero quality loss.
PNG is supported everywhere — websites, design tools, messaging apps — while BMP is rarely used outside of older Windows software.
Conversion happens locally in your browser using canvas — your BMP file is never uploaded.
BMP (Bitmap) is an uncompressed format — it stores every pixel's data directly with no compression, which results in much larger files than PNG or JPG for the same image.
No. PNG is a lossless format, so the converted image will look identical to the original BMP, just in a much smaller file.
Yes, drop multiple files and convert them all together, then download individually or as a ZIP.
