- Choose the target format (PNG, JPG, or BMP).

Frequently asked questions
Is this BMP converter really free?
Yes — free with no account, no watermark, and no limits.
What is a BMP file?
BMP (bitmap) is an old, uncompressed Windows image format. Files are large but simple, which is why some legacy software, embedded systems, and industrial tools still require it.
Should I convert my BMPs to PNG?
Usually yes — PNG is lossless like BMP but typically 5-10× smaller. Keep BMP only when the receiving software specifically requires it.
Are my files uploaded to a server?
No. All processing happens locally in your browser. Your files never leave your computer — close the tab and nothing remains.
