    BMP (Bitmap) is a file format that stores high-quality images without compression, often resulting in larger file sizes compared to formats like JPEG or PNG. But don’t worry, we’re here to help.

    SoftwareHow Bulk BMP Compressor is a free online tool that allows you to upload multiple BMP images (max 100 images at a time) and compress them quickly. Once the compression is done, you can download all the compressed files in a zip file. Furthermore, you can also compress your BMP images to a specific size like 100 KB or 128 KB.

    Our tool is 100% free to use, no need to sign up, no function limitation, and no catches. If you like our tool, the best way to show your appreciation is to buy us a cup of coffee.

    Frequently Asked Questions

    Why are BMP files so large?

    The reason why BMP files are usually large is that they store color data for each pixel in the image without compression, resulting in larger files compared to other image formats that use various compression algorithms.

    Can BMP images be compressed?

    Yes, BMP files can be compressed. However, you can reduce the size of BMP files using two types of compression: lossless compression and lossy compression.

    How does BMP compression work?

    BMP compression typically uses Run-Length Encoding (RLE), which reduces file size by replacing sequences of identical pixel values with a single value and a count. This method is efficient for images with large areas of the same color, resulting in a smaller file without losing image quality.

    Will my BMP images lose quality after compression?

    Yes, there will be up to 60% quality loss for BMP files using our tool to compress. This is due to the way our tool works to compress image files.

    Is it possible to compress BMP files from several MBs to KBs?

    Yes, it’s totally possible. Our tool can achieve up to 90% reduction in file size. It’s possible to compress a 2 MB BMP image to 200 KB.

    How long will it take to compress BMP file size?

    Normally, the compression process only takes a few seconds. But if you upload a few dozen of files, and your Internet is not that fast, extra seconds are probably needed.

    Will my uploaded BMP files be stored on the SoftwareHow server?

    No, we don’t store your files at all. Instead, all the images are uploaded and processed in your web browser. So your files are 100% safe and secure.
