PNG to BMP
Convert PNG images to BMP — right in your browser, nothing uploaded.
Drag & drop your PNG files here, or click to choose. Everything runs in your browser — nothing is uploaded.
PNG is a lossless format that supports transparency. This free PNG-to-BMP converter changes your PNG images into BMP entirely in your browser, so your files are never uploaded to any server. BMP is uncompressed (large files); transparency is flattened onto white. Convert as many files as you like at once, then download each result with one click — no signup, no watermark, and no limits.
Frequently Asked Questions
How do I convert PNG to BMP?
Drag your PNG file (or several) onto the box, or click to choose them. Each file is converted to BMP instantly, then you click Download to save it. It's free with no signup.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using your device's own processing, so your images never leave your computer or phone. That makes it safe for private or sensitive pictures.
Can I convert multiple PNG files at once?
Yes. Drop as many PNG files as you like and each one is converted and listed with its own download button, so batch conversion is quick.
What happens to transparency?
BMP does not support transparency, so any transparent areas are flattened onto a white background during conversion. If you need to keep transparency, convert to PNG or WEBP instead.
