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

On Windows 11 you don’t need extra software — the built-in Paint app can convert JPG to BMP directly:

Right-click your JPG file and choose Open with > Paint.

In Paint, click File > Save as.

From the format list, choose BMP picture (*.bmp).

Pick a folder and name, then click Save.

This keeps the image quality and creates a BMP file without any third-party tools. For multiple files you’ll need to repeat the steps, since Paint handles them one by one.

This is the simplest and most common way to convert JPG to BMP on Windows 11 using only system-built features.

On Windows 11 you don’t need any extra software — the built-in Paint app can directly convert JPG to BMP. Here’s the simplest way I’ve used myself:

✅ Steps to Convert JPG to BMP in Windows 11 (using Paint)

1. Right-click your JPG file → choose Open with → Paint.
   (Or open Paint from Start menu and drag the JPG into it.)
2. Once the image is open in Paint, go to the top left menu and click File → Save as.
3. From the options, choose BMP picture (*.bmp).
4. Pick the save location and file name, then hit Save.
5. That’s it — your picture is now in BMP format.

Notes

The original JPG stays safe — Paint creates a new BMP copy, it won’t overwrite unless you pick the same name.

Works fine for batch jobs too: just repeat the steps per file. If you need to handle many at once, you can select multiple JPGs, right-click → Open with Paint, then save each as BMP.

Once I was in a hurry to convert JPG to BMP, and I didn't have any tools, so I used a very "wild" method: drag it to Word, then take a screenshot and save it. Don't mention it, it really works!

My operation at that time was very simple:

1. Open Word, drag the JPG picture directly into it, and adjust it to the appropriate size.
2. Press Win+Shift+S on the keyboard (screenshot shortcut key), use the screenshot tool to select the picture, and then save it in BMP format.
3. Although it looks a bit "rustic", it is a rescue for me and is completely sufficient. If you only have a few pictures, don't have time to install software, and don't want to toss, this method is fast, accurate and ruthless, and it will get you done directly!

When considering the conversion of JPG to BMP, one essential factor to note is the difference in file formats themselves. JPG, being a lossy compressed image format, is optimized for reducing file size at the expense of some image quality. This makes it suitable for photographs and web use, where storage space and loading times are of concern. On the other hand, BMP (Bitmap) is an uncompressed format that retains image quality without any loss. This difference means that while BMP files can store more detailed information, they typically consume much more storage space compared to JPG files, which can be a concern if disk space is limited.

Another important aspect to keep in mind is the purpose of your conversion. If you need high-quality images for printing or graphic design work, BMP may be more appropriate due to its lossless nature. However, if your goal is to maintain a balance between quality and file size, you may want to reconsider the need for conversion. Additionally, different applications may offer varied benefits; for instance, some JPG to BMP conversion software leverage the BMP format for detailed editing and manipulation, while others may function equally well with JPG files.

Lastly, always remember to check the converted file for quality and integrity. Since BMP files can become significantly larger than JPGs, ensure that your storage solutions can accommodate this without causing issues down the line. Additionally, review the BMP image to verify that the conversion maintains the desired quality and color fidelity. If you encounter any artifacts or discrepancies, consider adjusting the conversion settings or trying a different tool to achieve better results. By being mindful of these factors, you can ensure a smooth and successful conversion process.

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!

Converting JPG to BMP on Windows 11 is pretty straightforward, but there are definitely some common pitfalls you’ll want to avoid to make sure everything runs smoothly. Make sure you know where the converted BMP is going. If you just click "Save" without checking, it might end up in some random folder and you'll be hunting for it later! 

JPG is a lossy format, which means when you convert it, you aren't preserving all the quality. While converting to BMP (which is lossless) should help keep quality, make sure that your original JPG isn’t super low-res. Otherwise, the BMP won't be much better.

Not all converters handle file types well. Some tools might mess up the image or crash halfway through, so stick to well-reviewed ones. Before you convert, it’s always a smart move to back up those original JPGs. You never know when you might need them again! BMP files don’t retain all the metadata found in JPGs (like camera settings, date taken, etc.). If that info is important to you, just keep it in mind.
