Frequently asked questions

Is this BMP to PNG converter free and private?

Yes. The conversion runs inside your browser, so your BMP files are never uploaded to a server. Our server only records that one image was converted, along with your network address, so that the daily limit shown above the converter can be applied.

Will I lose quality converting BMP to PNG?

No. Both formats store pixels exactly, so the picture is identical. Only the file size changes.

Is the photo's location and other metadata kept?

No. The converter writes a fresh PNG file with only the picture, so GPS location, camera details and dates stored inside the original are not copied. If you want a PNG with the original metadata, use a desktop editor instead.
