Lossless and smaller
PNG compresses the picture without changing a single pixel, so you get an identical image in a fraction of the space. It is the best replacement for BMP when you need exact quality, such as screenshots and diagrams.
Frequently asked questions
Are my photos uploaded to your server?
No. The conversion runs entirely inside your browser using your own device. Your files are never sent to us or to any third party, which is why it also works for private photos and large batches. Once the page has finished loading you can even switch off your internet connection and the tool keeps working.
Is anything lost in the conversion?
No. PNG is lossless, so the pixels stay exactly the same.
