Frequently asked questions
Is my PNG file uploaded anywhere?
No. The conversion runs inside your browser using WebAssembly. Your PNG file never leaves your device, which also makes it fast and safe for private files.
Can I convert multiple PNG files to BMP at once?
Yes. Add as many files as you like; they are converted one after another and you can download everything as a single ZIP.
Does converting reduce quality?
BMP is lossless, so no detail is lost. Files may be larger than the source.
