BMP to JPG: Shrink BMP Files for Email and Web
BMP files can be huge. Convert BMP to JPG to reduce file size and make images easier to share, upload, and store.
On this page
BMP is a legacy bitmap format that often produces very large files. If you are trying to email a BMP, upload it to a website, or store it efficiently, converting to JPG is usually the simplest fix.
Use: BMP to JPG.
Why BMP files are so big
BMP is essentially “raw-ish” pixel data. It was designed for simplicity, not efficiency. Compared to modern formats, BMP usually has:
- Minimal or no compression
- Large file sizes for photos
- Limited usefulness for web delivery
So if you see a 20MB BMP that looks like a normal photo, that’s expected.
When JPG is the right output
Convert BMP to JPG when:
- The image is photographic (or scan-like)
- You want smaller files
- You need broad compatibility
If the BMP contains sharp text or UI elements, PNG might look cleaner:
How to convert BMP to JPG (private)
- Open: BMP to JPG
- Drop your BMP file(s).
- Choose quality and metadata settings.
- Convert and download.
Picking a quality setting
Quality is the main trade-off with JPG:
- Higher quality = larger files, fewer artifacts
- Lower quality = smaller files, more artifacts (especially around text/edges)
If your BMP is a photo, you can usually lower quality a bit and still get a clean result. If it’s a scan with text, keep quality higher or switch to PNG.
What about metadata?
BMP typically doesn’t carry the same kind of EXIF metadata you’d see in camera photos, but if you’re converting images for sharing, it’s still worth stripping metadata when possible as a privacy default.

If you’re publishing online
JPG is a great “compatibility” output, but if your end goal is a website, you can often make the final file even smaller by converting the JPG to WebP afterwards:
That gives you a clean workflow: BMP -> JPG for compatibility, then WebP for web performance.
FAQ
- Will converting BMP to JPG reduce quality? JPG is lossy, so technically yes. In practice, with high-quality settings, it’s usually visually clean, and the file size reduction is often worth it.
- Why not use PNG instead? PNG is lossless, but for photos it can be much larger than JPG. If you need small files, JPG is often better.
- Can I batch convert BMP files? Yes. Convert multiple files at once (up to 20) and download the results.
- Is this private? Yes. QuickImager converts locally in your browser with no uploads.
If you’re unsure, convert one file first, check quality and size, then batch the rest.
