I have a little tool I created that will take a URL and convert the content at that URL into a JPEG image.
I’m not sure it’ll be useful and was only created/hacked together because of an idea that I had that I have since abandoned. The backend uses wkhtmltoimage-amd64 to do the magic the rest is PHP handler.
I have added the ability to choose width of the snapshot using “width” paramater. For example: https://techish.net/pub/websitesnapshot/?url=http://www.google.com/&width=640
Note that the width value must be less than 2048.
You can see other people’s images by adding images/ to the end of the above URL.
