BMP vs JPG: Format Comparison
Key differences between the two formats
When to Convert
Common scenarios where this conversion is useful
Rescuing space from legacy screenshots
Older Windows applications and some screen capture tools save as BMP. Converting these to JPG can free up 90-95% of the storage space without visible quality loss.
Sharing images from scientific instruments
Some lab equipment, medical imaging systems, and industrial cameras output BMP files. Convert to JPG for easy sharing via email or collaboration tools.
Emailing large bitmap files
A single BMP image can be 15-50MB. Converting to JPG brings it down to 500KB-2MB, well within email attachment limits and much faster to send.
Uploading to web platforms
Most websites and social media platforms reject BMP uploads due to their enormous file size. Converting to JPG makes them uploadable anywhere.

Frequently Asked Questions
Dramatically smaller - typically 90-95% reduction. A 15MB BMP photo becomes a 500KB-1.5MB JPG. BMP stores every pixel uncompressed (3 bytes per pixel), while JPG uses highly efficient lossy compression.
There is minor quality loss from JPG compression, but at the default 92% quality setting it's invisible to the human eye for photographs. The massive file size reduction far outweighs the imperceptible quality difference.
BMP (Bitmap) is one of the oldest image formats, dating back to early Windows. It stores every pixel's color value without any compression. A 4000x3000 photo requires 36MB as BMP (4000 x 3000 x 3 bytes) but only ~2MB as JPG.
BMP is simple to read and write, has no compression overhead, and guarantees exact pixel values. It's used in embedded systems, scientific instruments, legacy Windows applications, and as a raw interchange format.
No. The JPG has exactly the same pixel dimensions as the BMP. Only the file format and compression method change.
Yes, use our BMP to PNG converter. PNG offers lossless compression and transparency support. However, JPG will produce smaller files for photographic content.
No. The entire conversion happens in your browser. Even though BMP files can be very large, they're processed locally on your device without any network transfer.
Yes. The browser's native image decoder handles all standard BMP variants including 24-bit, 32-bit, and indexed color BMPs.
