BMP to JPG Converter

Converting BMP to JPG reduces uncompressed bitmap file sizes by 90–98% using lossy JPEG compression. BMP files store every pixel without compression — a standard 1920×1080 screenshot is over 6 MB as BMP but only 150–400 KB as JPG. This dramatic size reduction makes images practical for web use, email attachments, and storage on space-limited devices. JPEG compression is particularly effective for photographs and complex images with smooth gradients, achieving excellent visual quality even at high compression ratios. SublimePDF converts BMP to JPG with adjustable quality settings so you control the size-versus-quality tradeoff.

How to Convert BMP to JPG Online

1

Upload your BMP file

Drag and drop your .bmp image. BMP files are large — a 24-bit 1920×1080 image is ~6 MB — so the upload may take a moment on slower connections.

2

Set JPEG quality

Adjust the quality slider from 1 (maximum compression, smallest file, visible artifacts) to 100 (minimum compression, largest file, near-lossless). Quality 80–85 offers the best balance for most images.

3

Download your JPG

Your converted image is typically 90–98% smaller than the original BMP. At quality 85, a 6 MB BMP becomes roughly 200–400 KB with negligible visible quality loss.

Your files never leave your device. All conversion happens locally in your browser using WebAssembly technology.

BMP to JPG Conversion FAQ

How much quality is lost converting BMP to JPG?
At quality 85+, the difference is virtually imperceptible to the human eye. Compression artifacts (slight blurring near sharp edges) only become noticeable below quality 60.
What happens to transparency in 32-bit BMP files?
JPEG does not support transparency. The alpha channel is composited against a background color (white by default, configurable) before JPEG encoding.
Is JPG a good choice for text and line art?
JPG compression can introduce artifacts around sharp edges in text and line art. For these use cases, PNG (lossless) is usually a better choice. Use our BMP-to-PNG converter instead.
Does the converter handle BMP files with RLE compression?
Yes. Both uncompressed BMP and RLE-compressed (RLE4/RLE8) BMP variants are decoded correctly before JPEG encoding.
Can I convert multiple BMP files at once?
Yes. Upload multiple BMP files and they'll each be converted to JPG individually. Download them as separate files or in a single ZIP archive.
