How to Compress BMP Images Online in 3 Easy Steps
Follow these three simple steps to compress BMP images individually or in bulk. Adjust the quality and color dithering before processing. No software installation required. Free and secure.
Choose BMP Images
Select BMP files from your device, choose an entire folder, or drag and drop multiple images into the tool.
Adjust Quality and Dithering
Use the quality slider to control the number of colors. Enable color dithering when you want smoother transitions in reduced-color gradients.

How Does the CompressFly BMP Compressor Work?
The CompressFly BMP compressor uses RLE compression and an 8-bit color palette to reduce BMP file size while keeping the output in BMP format. The quality slider controls the number of palette colors, while optional dithering can smooth color transitions. BMP images are processed directly in your browser, individually or in bulk, with no files sent to a server and no signup required.
What "in your browser" means
