Frequently asked questions
Is it free to convert BMP to PNG?
Yes, completely free, without sign-up or watermarks.
Are my images uploaded?
No. Conversion runs in your browser, so your images never leave your device.
Can I convert many files at once?
Yes. Add as many images as you like and download them all as one ZIP.
What happens to transparency?
PNG and WebP keep transparent areas. JPG has no transparency, so transparent areas become white.
