Javascript devs, what's the best HTML-to-Image conversion library out there? Ideally should: 1. Support the usual 

PNG

 | 

JPG

 | 

SVG

 | 

PDF

 formats. 2. Be an NPM package that runs in-browser (i.e. no back-end required). Preferably open-source & free. But don't mind paid licenses.

Thanks, but see my point #2 above 😃

Html2Canvas might be your best bet

dom2image for PNG, JPG, SVG: https://www.npmjs.com/package/dom-to-image (it's better than html2canvas) dom2pdf for PDF: https://www.npmjs.com/package/dom-to-pdf Past week I wrote a tutorial on generating an image and copying it to clipboard in JS, let me know if you think it would be helpful for you!

If you're doing it on the backend and want more granular control, Puppeteer is a good option.
