Why WebP for websites
WebP files are usually a quarter to a third smaller than JPG or PNG at the same visual quality. Lighter pages load faster, which helps both visitors and search rankings.
Every current browser displays WebP. Keep a JPG copy only if you need to send the file to software that does not understand WebP.
Picking a quality value
80 is a good starting point for photographs. Try 70 for even smaller files and check that edges and text still look clean.
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.
Does WebP support transparency?
Yes, including soft semi-transparent edges, so it can replace PNG for many graphics.
