Why convert BMP to JPG?

BMP is an old, uncompressed bitmap format. The files are enormous (a single image can be tens of megabytes) because nothing is compressed at all. Converting BMP → JPG, also written JPEG, shrinks them dramatically while keeping the picture looking the same. JPG also opens in everything, where BMP can feel clunky on modern phones and the web. Since JPG is lossy, you get a quality slider to choose how small to go. For most BMPs the size drop is huge even at high quality. The conversion runs in your browser, privately.

How do I convert a BMP to JPG online for free?

Add your BMP file, pick a quality level for the JPG (higher keeps more detail, lower makes a smaller file), then download the result, which is usually a fraction of the original size. It all happens in your browser, so the image is never uploaded.

How to convert BMP to JPG

  1. 1Drop your .bmp files in, or tap Upload (up to 10 at once).
  2. 2Set the quality: high keeps detail, lower makes an even smaller file.
  3. 3Click Convert. Each file is processed on your device.
  4. 4Download your JPGs individually or as a batch. Nothing is uploaded.

BMP vs JPG: why the size difference?

BMP is an old, uncompressed bitmap format: it stores every pixel raw, so a single image can run to tens of megabytes. JPG compresses the image, typically cutting the size by 90% or more while still looking the same to the eye. Convert BMP to JPG when you need a small, portable, universally-viewable file. If you need perfect quality instead, BMP to PNG stays lossless while still shrinking the file versus BMP.

Frequently asked questions

How much smaller will the JPG be?
Usually 90% or more, because BMP stores pixels uncompressed and JPG compresses them. At high quality the picture still looks the same.
Will I notice a quality drop?
At a high quality setting the difference is invisible for normal viewing. Lower the slider only when you want the very smallest file.
Why are BMP files so large?
BMP stores every pixel uncompressed, so file size balloons. JPG compresses the image, often cutting size by 90% or more.
Will the JPG look worse?
At a high quality setting the difference is invisible for normal viewing, while the file is a fraction of the size.
Can I adjust how much it compresses?
Yes, a quality control lets you choose between a sharper, larger file and a smaller one.
Need a lossless result instead?
Convert BMP to PNG to keep perfect quality while still shrinking the file versus BMP. BMP to PNG
