Convert BMP to JPG
Drop your BMP files and download compact JPG copies, encoded entirely in your browser. Perfect for shrinking the huge uncompressed bitmaps that old Windows software and scanners still produce.
How to convert BMP to JPG
- Drop your BMP files into the box below.
- The browser decodes each bitmap and a Canvas exports a high-quality JPG.
- Download the JPG copies individually or as a batch.
Why convert BMP to JPG?
BMP files are enormous because they store pixels with little or no compression — a format that made sense in the 1990s but wastes storage and bandwidth today. For photographs and scanned images, converting BMP to JPG cuts the file size by 90% or more with no quality loss visible to the human eye, and produces a file that every email client, website, marketplace and printing service accepts. JPG is the safe, universal delivery format; BMP is a relic that many modern upload forms reject outright. Convert BMP to JPG when you need to email an old bitmap, attach it to a form, print it, or simply stop a folder of legacy screenshots from eating gigabytes. Because JPG has no transparency, any transparent areas are flattened onto white. If your bitmap is sharp line art or you need to keep every pixel exactly, use the BMP to PNG converter instead.
How we compare
The closest peer to this tool is Google's Squoosh, which also runs fully in your browser. Squoosh focuses on compression for the modern web and does not handle HEIC or batch conversion. Cloudconvert and Convertio cover more formats but upload your files to their servers and meter usage.

Frequently asked questions
How much smaller will the JPG be?+
Typically 90% or more for photographs, because BMP is nearly uncompressed while JPG uses efficient lossy compression.
Are my files uploaded?+
No. Decoding and JPG encoding both run inside your browser tab.
Will I lose quality?+
JPG is lossy, but at the default quality 95 the difference is invisible on photographs. For crisp text or line art, prefer BMP to PNG.
What happens to transparency?+
JPG has no alpha channel, so any transparent areas in the BMP are filled with white. Use BMP to PNG to keep transparency.
What is the maximum file size?+
Limited only by your browser's memory, which comfortably handles large bitmaps on desktop.
Which browsers are supported?+
Every modern browser — Chrome, Edge, Safari, Firefox, Opera and Brave.
