BMP to JPG Converter

Convert BMP images to JPG at the original dimensions, one file at a time or as a batch.

How to use the BMP to JPG Converter

  1. Drop your BMP files into the upload area, or click it to pick files from your device.
  2. Adjust the quality slider if the output format is a lossy one. Higher values keep more detail and produce larger files.
  3. Press Convert and wait for the progress bar to finish.
  4. Download each JPG file individually, or use Download all as ZIP when you converted several images at once.

How to convert BMP to JPG

Add one or more BMP files, pick a quality level if the option is shown, and press Convert. Each image is decoded, redrawn on a canvas and saved again in the JPG format. Converting several files at once is supported, and the results can be downloaded together as a ZIP archive.

BMP and JPG compared

BMP is an uncompressed bitmap format from the Windows world. Files are large because every pixel is stored literally, but nothing is ever compressed away. It works best for legacy Windows software and simple pixel-level work, and is a weaker choice for anything published on the web, because of the file size.

JPG (also written JPEG) is the oldest widely supported photo format. It uses lossy compression, which keeps photographs small but discards some detail every time the file is saved. It is the better fit for photographs, scanned pictures and any image with soft gradients, while it is less suitable for flat graphics, screenshots with text and anything that needs a transparent background.

Choosing a quality level

JPG is a lossy format, so the quality slider decides the trade-off between file size and detail. Around 80–90 is a sensible range for photographs: the difference is hard to see, while the file is far smaller than at 100. Flat graphics with sharp edges usually need a higher setting, because lossy compression tends to blur hard edges.

What to check after converting

  • Open the result at full size and look at edges, text and flat colour areas first — that is where compression artefacts appear.
  • Compare the file size against the original. If a JPG file is larger than the BMP source, lower the quality slider or reconsider the format.
  • Check that the image dimensions are unchanged. Conversion never resizes an image; use the resizer tools for that.

Format support in browsers

Saving files relies on the image encoders built into your browser. PNG, JPG and WebP are available almost everywhere. AVIF encoding is only present in some recent browsers, and the tool will tell you clearly when the format you picked cannot be written on the device you are using, rather than producing a broken file.

Frequently asked questions

Does converting BMP to JPG reduce the image quality?
JPG uses lossy compression, so some detail is discarded when the file is written. At a quality setting of 80 or above the difference is usually invisible at normal viewing size. Keep the original file if you plan to edit the image again later.
Can I convert several BMP files at once?
Yes. Select or drop multiple files, run the conversion, and download the results one by one or together in a single ZIP archive.
Are the image dimensions changed during conversion?
No. The width and height stay exactly the same. If you also need a different size, use the Image Resizer after converting.
