BMP Converter
Convert images to uncompressed BMP format for legacy systems and print workflows.
Convert JPG, PNG, WebP, AVIF, TIFF, or GIF images to BMP. BMP stores raw pixel data with no compression, making it suitable for legacy Windows applications, print workflows, and embedded systems that require uncompressed bitmaps. All conversion runs entirely in your browser inside a Web Worker, so your images never leave your device. Note that BMP files are typically 5–10× larger than JPG/PNG; use the optional max-width resize to control output size. Browser support for BMP encoding varies — older Safari may produce PNG fallbacks.

FAQ
Common questions and answers about this topic.
Are my images uploaded to a server?
No. All conversion runs entirely in your browser inside a Web Worker. Your images never leave your device.
Why are BMP files so large?
BMP stores raw pixel data without any compression — every pixel takes 24 or 32 bits. A 1920×1080 image is roughly 6 MB as BMP versus 200–500 KB as JPG. BMP is appropriate when an application explicitly requires uncompressed input; for general use, prefer PNG (lossless compression) or JPG (lossy).
Is BMP supported on all browsers?
Most browsers support reading BMP. For encoding (saving as BMP), Chrome and Edge work natively; Firefox and Safari may fall back to PNG. If your downloaded file appears as PNG instead, your browser does not support BMP encoding — try Chrome or use a desktop tool.
