Convert BMP to JPG
Old scanners, Windows tools, and industrial software love producing BMP files nobody else wants. For photographic content, converting BMP to JPG collapses those enormous files down to a manageable size.
The converter runs locally with JPG preselected and a quality slider so you control the size/fidelity tradeoff. For screenshots or line art, consider BMP to PNG instead — JPG artifacts show most on hard edges.

How it works
Select one or more images.
Choose the target format; consequences (like losing transparency in JPEG) are shown before converting.
Pick a background color if converting transparency to JPEG.
Convert and download individually or as a ZIP.
What the tool does
- PNG, JPEG, and WebP output
- Batch conversion with per-file success/failure isolation
- Explicit background selection when alpha meets JPEG
- Quality control for lossy targets
- ZIP download with deterministic file naming
How the result is verified
Every output is re-decoded to confirm it parses as the target format with the expected dimensions; failures are isolated per file.
Frequently asked questions
How much smaller will the JPG be?
Often 95%+ smaller than the raw BMP for photographs. The tool reports the exact output size measured from the encoded bytes.
When should I pick PNG instead?
When the image contains text, UI, diagrams, or any hard edges you want kept crisp — PNG is lossless and handles those better than JPG at any quality.
