Convert BMP to JPG Online

We produce hundreds of Windows screenshots weekly for internal documentation, and they come out as BMP files that are too large to attach to tickets. Batch converting them to JPG cut our storage use by 80%.

Our scanner software outputs BMP by default and the web portal only accepts JPG. This converter processed 400 scans in a few minutes with no quality loss that I could notice.

Needed to upload BMP images to a CMS that only supports JPG and PNG. The batch mode worked perfectly, though I had to manually set the quality level for each run — a preset would be a nice addition.

Convert BMP to JPG — Frequently Asked Questions ▼

Is BMP to JPG conversion lossy?

Yes. JPG uses lossy compression, so converting from an uncompressed BMP introduces some quality loss. For photographs and natural images, the loss is barely visible at high quality settings. For graphics with sharp lines, text, or flat colors, the compression artifacts are more noticeable — use PNG instead of JPG for those.

How much smaller will the JPG be compared to the BMP?

Typically 90-95% smaller. A 6 MB BMP photograph commonly becomes a 200-400 KB JPG at high quality settings. The exact ratio depends on image complexity — high-detail photos compress less than images with large uniform areas.

Does BMP to JPG conversion remove transparency?

BMP files do not support standard alpha channel transparency, so there is nothing to lose. If you have a 32-bit BMP with an alpha channel (uncommon), those values will be dropped in the JPG, replaced with a solid background color.

Can I open the converted JPG in Photoshop or Lightroom?

Yes. JPG is natively supported by every major image editing application, including all versions of Photoshop, Lightroom, GIMP, Affinity Photo, and any other editor you are likely to use.

What is the file size limit?

The online converter accepts BMP files up to 50 MB. This covers most single-image use cases. Larger images or bulk conversions require the desktop Total Image Converter, which has no file size limit.

Can I batch convert many BMP files to JPG?

The online tool processes one file at a time. For bulk jobs, use Total Image Converter (desktop): TotalImageConverter.exe C:\bmp C:\jpg /ConvertTo jpg /ProcessRecursively. It also supports JPG quality level settings per batch.

What desktop application handles large-scale BMP to JPG conversion?

Total Image Converter runs on Windows and converts entire folder trees of BMP files to JPG with configurable quality settings, command-line support, and Task Scheduler integration. It is available at coolutils.com/TotalImageConverter with a 30-day free trial.

What Is BMP?

BMP (Bitmap) stores image data as raw, uncompressed pixels. A 1920x1080 24-bit BMP is approximately 6 MB. This makes BMP impractical for sharing, web use, or any space-constrained environment. It remains common as output from legacy Windows applications and built-in screen capture tools.

What Is JPG?

JPG uses lossy compression designed for photographs and complex, color-rich images. At typical quality settings, it reduces file size by 90%+ with minimal visible degradation. JPG does not support transparency and is not ideal for text-heavy graphics (use PNG for those), but for photos it is the de facto standard format for sharing and web publishing.

Category	Image File
Description	May be the simplest file format, BMP was developed jointly by Microsoft and IBM. That is why it is widespread on Windows platform. This extension is characterized a raster graphic format which is recognized by many programs today. In comparison with other bitmap formats, JPEG and GIF, BMP keeps color data for each pixel in the image and doesn't compress images to decrease a file size. That is what makes it perfect file format for printable images.

File extension	.JPG, .JPEG, .JPE, .JFIF, .JFI
Category	Image File
Description	JPG is the file format for images made by digital cameras and spread throughout the world wide web. Saving in JPG format an image loses its quality, because of the size compression. But at the end you have a much smaller file easy to archive, send, and publish in the web. These are the cases when an image's size matters more than image's quality. Nonetheless, by using professional software you can select the compression degree and so affect the image's quality.
