About BMP to PNG
BMP files are uncompressed; PNG stores exactly the same pixels in a fraction of the space and works on the web.
Processing happens in this browser tab: your images are never uploaded, and the result is ready as soon as you download it. Large photos take a moment longer on phones; nothing is limited by size.
BMP to PNG: frequently asked questions
How do I convert BMP to PNG?
Choose one or more BMP files, adjust the settings if you need to, and select Convert. Each file is saved as PNG with the same name and the right extension, and several files can be downloaded together as a ZIP.
Why convert BMP to PNG?
BMP files are uncompressed and very large. PNG stores exactly the same pixels in a fraction of the space and works on the web.
Is transparency kept when converting BMP to PNG?
BMP files rarely contain transparency; any that is present is kept in the PNG.
Is any quality lost?
No. PNG is lossless, so the pixels are identical to the BMP.
Are my BMP files uploaded anywhere?
No. The conversion runs in your browser on your device, so the images are not sent to KittySuite or anyone else.
