How do I convert jpg to bmp file on my Windows 11?

Recently I want to convert a bunch of JPG to BMP format to use as materials for an old software (it can only read BMP, so speechless). I thought that the "Paint" that comes with Windows 11 can do it ...

I have encountered similar problems before. I had to convert a bunch of JPGs to BMP because the company's old software only recognized the BMP format (really speechless). After a lot of searching, I finally found a few simple methods. I will share my experience below. They are all effective and I hope they can help you!

Method 1: Use the built-in drawing tool of Windows
This method is the simplest. You don't need to download any additional software at all. I just relied on it to get it done.

  1. Right-click your JPG file, select "Open with", and then click "Paint".
  2. After opening, click "File" → "Save as" → "BMP Picture" in the upper left corner.
  3. Select the save location and click OK to complete.
  4. I had dozens of pictures at the time. I saved them one by one using this method. Although it was a little troublesome, it was simple and reliable.

Method 2: Use the command line tool for batch conversion
Later, I found that converting them manually one by one was too slow, so I tried the command line tool ImagesMagck(free and open source).

  1. First go to the official website to download ImagesMaick, and then install it.
  2. Open the "Command Prompt" (Win+R, enter cmd, and press Enter).
  3. Enter the following command to batch convert:
magck mogrify -format bmp *.jpg


(Make sure all your JPG files are in the same folder)


Convert all JPGs to BMP in a few seconds, super convenient! However, you need to install a tool, which is a bit of a hassle, but later the efficiency is much improved.

Method 3: Use online bmp tools to get it done
If the number of files is not large, online conversion tools are actually quite convenient, such as Online Convert or Converitio.

  1. Open the website and upload your JPG file.
  2. Select BMP format and click "Convert".
  3. Download the converted BMP file.
  4. I tried it and the effect is not bad, but if there are many pictures, this method is a bit slow and depends on the network speed.

If there are not many files, it is most convenient to use a drawing tool; if there are many files and you don't want to convert them one by one manually, ImagesMagck is an efficient choice; if you are too lazy to install software, online tools are also a good alternative. I hope these methods can help you successfully complete the conversion from JPG to BMP. Good luck!
