BMP files are uncompressed and large. Converting to PNG gives you the same quality at a fraction of the size. fwip does this entirely in your browser — your file never leaves your device.

fwip works differently. The processing engine runs entirely in your browser. Your BMP is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

Frequently asked.

How do I convert BMP to PNG?
Drop your BMP file into fwip. It converts to PNG instantly in your browser. Download the result.
Is my BMP file uploaded?
No. Conversion runs entirely in your browser. Your file never leaves your device.
Why convert BMP to PNG?
BMP is uncompressed — a 10MB BMP is typically 1-2MB as PNG with zero quality loss. PNG is also more widely supported.
Is there any quality loss?
No. PNG is lossless — it compresses the data without discarding any pixels. The output is pixel-perfect identical to the input.
Can I convert BMP to JPG instead?
Yes. fwip has a dedicated BMP to JPG tool for when file size is more important than preserving every detail.
