Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many PNG files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting PNG to BMP reduce quality?
No. Both formats are lossless, so every pixel is kept.
Does BMP keep transparency?
BMP doesn't support transparency, so transparent areas are filled with a background color you can choose.
