Common Questions
What is BMP format and when is it used?
BMP (Bitmap) is an uncompressed image format commonly used in older systems and legacy applications. BMP files are typically much larger than modern formats. They're still found in Windows systems, but for most purposes, newer formats like JPEG or PNG are more efficient.
Why should I compress BMP files?
BMP files are often enormous due to lack of compression. Compressing and converting them to JPEG can reduce file size by 80-90%, making them easier to store, email, and share. This is especially useful when working with legacy BMP files from older systems.
Is it safe to convert BMP to JPEG?
Yes. All processing happens in your browser with no data stored on servers. Lossless mode preserves quality, while lossy achieves greater compression. You can preview both versions before downloading to ensure the result meets your needs.
