About PNG

PNG is lossless and keeps transparency, which makes it right for logos, screenshots and line art — and larger than JPG for photographs.

Nothing is uploaded

Other bmp to png converters send your files to a server, convert them there, and send them back — leaving a copy on a machine you do not control. This one uses your browser's own image engine, so the file never leaves your device. No account, no queue, no size cap, no watermark.

Questions

How do I convert BMP to PNG?

Drop your BMP files onto the panel above, check the output is set to PNG, and press the button. The conversion happens in this browser tab, so nothing is uploaded and there is no waiting for a server.

Is it free, and is there a limit?

Free, with no account and no file count or size limit. Because your own device does the work, there is nothing for anyone to meter.

Are my BMP files uploaded anywhere?

No. There is no server involved. Load this page, disconnect from the internet, and the converter still works — which is the simplest proof that your files are not going anywhere.

Will converting BMP to PNG lose quality?

PNG is lossless, so the conversion itself discards nothing. The file may be larger than the original, which is normal for lossless formats.

Can I convert a whole folder at once?

Yes. Add as many files as you like — they are processed one at a time to keep memory use low, and you get a single zip at the end.
