Frequently asked questions
Is my BMP file uploaded anywhere?
No. The conversion runs inside your browser using WebAssembly. Your BMP file never leaves your device, which also makes it fast and safe for private files.
Can I convert multiple BMP files to PNG 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?
PNG is lossless, so no detail is lost. Files may be larger than the source.
