09:56:29 # Life Grabbing screenshot. I wanted to know the size of screenshot generated by canvas.toDataURL so I wrote a web app that just measures the size at 60fps because I could. From output I can see webp: 19087 png: 115818 jpg: 115818, so I figured webp is really good at this, or maybe chrome is really good at using webp. and png and jpg look like they are the same size... hmm.. why? UPDATE: image/jpg generated png and image/jpeg generated jpeg.
