The complete guide to BMP to JPG Converter
Last updated June 1, 2026BMP (Bitmap) is Windows' native uncompressed image format — used by older software, Windows screenshot tools (Pre-Win10), and some industrial and medical equipment. BMP files are enormous (a 1920×1080 BMP is around 6 MB uncompressed). Converting BMP to JPEG compresses them to a fraction of that size with no visible quality difference at normal viewing sizes.
Convertify's BMP to JPG converter handles single and batch conversions in the browser, with a quality slider for balancing size and fidelity. No upload required — useful when the BMP contains proprietary CAD or medical image data.

Step-by-step: how to use BMP to JPG Converter
- 1
Upload BMP files
Drop one or many .bmp files onto the upload zone.
- 2
Set JPEG quality
80-85% is the recommended default for photos. For images with text or sharp edges, 90-95% preserves clarity better.
- 3
Convert and download
JPGs download individually or as a ZIP for batches. File size reduction is typically 90-97% vs the original BMP.
Real-world scenarios
Windows Paint and legacy screenshot exports
Older Windows apps often save screenshots as BMP by default. Convert to JPG before sharing by email or uploading — a 5 MB BMP becomes a 100-200 KB JPEG.
Industrial and medical equipment outputs
Some specialized hardware (machine vision cameras, older medical imaging stations) exports images as BMP. Convert to JPG for compatibility with standard review and reporting software.
Reducing archive storage
A folder of legacy BMP files takes dramatically more disk space than the equivalent JPEGs. Batch-convert the archive to reduce storage by 90%+ for archival copies that don't need to be edited.
Troubleshooting and edge cases
The BMP has colors that look wrong after JPEG conversion.⌄
Very unusual for standard 24-bit BMPs. If you have a 1-bit, 4-bit, or 8-bit indexed color BMP, the color palette may not convert perfectly. Convert to PNG first (which handles indexed color well), then PNG to JPG if size reduction is needed.
