Privacy. This tool works entirely inside your browser. Your file is never sent to us, never saved, and never seen by anyone else. Read how we handle files

Converts an old BMP file to PNG without altering a single pixel. PNG is lossless, so the image is preserved exactly, but it is properly compressed — usually a half to a tenth of the BMP size.

This is the conversion to choose when the image is a screenshot, a scanned document or a drawing and you want it kept exactly as it is. For a photograph, BMP to JPG gives a far smaller file.

How to use it

  1. Choose your files, or drag them onto the box above.
  2. Press the convert button and wait a moment.
  3. Download the result. Nothing is kept once you leave the page.

Files it accepts

  • BMP (.bmp)

Questions

Is any quality lost?

None. PNG is lossless, so every pixel comes out identical to the BMP.

PNG or JPG for an old BMP?

PNG for screenshots, scans and drawings. JPG for photographs, where the file will be very much smaller.

Which files can I use?
