Is BMP to PNG conversion free?
Yes, Fileza.io converts BMP to PNG completely free with no limits on file size or number of conversions. No hidden fees, no watermarks, and no account required.

Will I lose quality converting BMP to PNG?
No quality is lost. PNG uses lossless compression, preserving all original data from your BMP file.

Is it safe to convert BMP to PNG online?
Absolutely. Unlike most online converters, Fileza.io processes your files entirely in your browser using WebAssembly. Your BMP files are never uploaded to any server — the conversion runs on your own device, keeping your files 100% private.

Yes, Fileza.io supports batch conversion. Drag and drop multiple BMP files at once and they will all be converted to PNG simultaneously. Download them individually or as a ZIP archive.

Does BMP to PNG conversion work on mobile?
Yes, the converter works on any device with a modern web browser — iPhones, iPads, Android phones, and tablets. No app installation required.

Will the converted PNG files be smaller or larger than BMP?
File sizes depend on content and quality settings. BMP files are typically very large (uncompressed), while PNG files are medium to large.

How long does BMP to PNG conversion take?
Most conversions complete in seconds. The exact time depends on file size and your device performance. Since processing happens locally in your browser, faster devices convert more quickly.

Will my BMP images have transparency after converting to PNG?
PNG supports transparency, but the original BMP does not contain transparency data. The converted file will have a white background by default. To add transparency, edit the image after conversion.
