PixConvert BMP to JPG
BMP files are uncompressed bitmaps that waste storage and bandwidth. Converting BMP to JPG applies efficient lossy compression, often shrinking files by 90% or more while keeping photographs looking sharp.

Why Convert BMP to JPG
BMP (Bitmap) is one of the oldest image formats, dating back to early Windows. It stores pixel data with minimal or no compression, which means BMP files are enormous. A single 1920x1080 photo in BMP format can be 6MB or more — the same image as a JPEG is typically 200-400KB. That is a 90-95% reduction in file size.
BMP files are impractical for modern use. They cannot be uploaded to most social media platforms, they are too large for email attachments, they slow down websites, and they waste storage space. Converting BMP to JPG solves all of these problems while preserving the visual quality of photographs.
JPG (JPEG) uses lossy compression specifically optimized for photographs. It discards visual information that the human eye cannot easily detect, achieving dramatic file size reductions. At quality 80-85, most people cannot distinguish a JPEG from the original BMP — yet the file is 90% smaller.
You may encounter BMP files from legacy software, medical imaging devices, older scanners, screen captures on some systems, or files generated by vintage applications. Whatever the source, converting to JPG makes these files usable in modern workflows. Pixotter handles the conversion entirely in your browser — your BMP files are never uploaded to any server, which is especially important for sensitive images from medical or legal sources.
Frequently Asked Questions
Does converting BMP to JPG reduce image quality?
Yes, slightly. JPG uses lossy compression, which means it discards some visual data to reduce file size. At quality 80-90, the difference is imperceptible for photographs. You may notice minor artifacts in areas with sharp edges or flat colors (like text or diagrams). For these types of images, converting to PNG instead preserves quality perfectly.
How much smaller will my JPG file be?
Typically 90-95% smaller than the original BMP. A 6MB BMP photo converts to approximately 200-400KB as a JPEG at quality 80. The exact reduction depends on image content — photos with lots of detail compress less than simple graphics. Pixotter shows you the before and after file sizes so you can see the exact savings.
Can I convert BMP to JPG without losing transparency?
BMP files rarely contain transparency data, but if yours does, converting to JPG will lose it — JPEG does not support transparency. If you need to preserve a transparent background, convert to PNG instead. Pixotter offers both conversion options and you can see a preview before downloading.
Why do I still have BMP files?
BMP files are common from legacy Windows applications, older scanners and medical imaging devices, Paint in older Windows versions (which defaulted to BMP), screen capture tools that save uncompressed output, and some industrial or scientific equipment. If you regularly receive BMP files from these sources, Pixotter's batch conversion lets you process them all at once.
Should I convert BMP to JPG or PNG?
Convert to JPG if the image is a photograph — you get the smallest file size with excellent quality. Convert to PNG if the image contains text, diagrams, screenshots, or graphics with sharp edges — PNG is lossless and preserves these details perfectly. When in doubt, try both and compare the results. Pixotter makes it easy to test different formats.
