Why convert BMP to PNG?

  • PNG files are usually smaller than BMP for the same picture, so pages load faster and uploads finish sooner.
  • PNG is supported far more widely than BMP, so the file is easier to open, share and upload.
  • PNG is made for screenshots, logos, text graphics and cut-outs.

What to expect when converting BMP to PNG

  • Your original BMP file isn’t changed: you download a new PNG copy.
  • The PNG keeps the pixel dimensions of your BMP.

Frequently asked questions

How do I convert BMP to PNG?
Upload your BMP file above. It is converted to PNG automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.
Does converting BMP to PNG lose quality?
No. Both formats are lossless, so every pixel is kept exactly.
BMP or PNG: which should I use?
Use BMP for older Windows programs, embedded devices and tools that need raw pixels. Use PNG for screenshots, logos, text graphics and cut-outs. Keep in mind the main drawback of PNG: large files for photographs.

BMP stores pixels with no compression at all. Files are large, but very old or simple software that can’t read modern formats can usually read a BMP.
