Frequently asked questions
Are my PNG files uploaded to a server?
No. The conversion runs 100% in your browser using your own device, so your images never leave your computer.
Can I convert several PNG files at once?
Yes — drop a whole batch, convert them together, and download them individually or as one ZIP archive.
Does the converter work offline?
Yes. Once the page has loaded it keeps working with no internet connection.
What happens to transparent areas?
BMP cannot store transparency, so transparent pixels are filled with a background colour. White is the default and you can change it before converting.
