Three options

Use Online convert's API

http://apiv2.online-convert.com/

Run your own node.js server and use Potrace or AutoTrace

https://www.npmjs.com/package/potrace used by Online convert https://www.npmjs.com/package/autotrace

Or use imagetracerjs client side.

This project supports both bitmap to SVG and SVG to bitmap (png/jpeg/gif/etc),offers flexible settings, different renderers, JavaScript API for node.js and browser, and Command line .

If configured correctly it generates good results and small svg size. If you just want to transform logos / drawings then no config is needed but if photographs / realistic paintings then some you need to play with the settings until satisfied with size / quality ratio.

It has a playground although right now I'm working on a better one since more features has been added:

What you're asking isn't really possible. I mean, you could try to do it, but I doubt the results would be particularly satisfying.

SVG to JPEG is a one-way conversion; converting a raster image to a vector image is non-trivial, see this question.

    That said, it is possible to port e.g potrace to javascript using HTML5 canvas. It will likely be a bit slow, and it will require a bit of porting work, but it's not impossible. Tracing raster images and producing nice vector graphic results is a hard problem OTOH. – Erik Dahlström Oct 26 '10 at 12:05
  • @Erik Dahlström: For some value of "possible". – Williham Totland Oct 29 '10 at 07:27
  • Hi there. Do you know if this is the current state of affairs in 2019? Thanks. – Crashalot Aug 27 '19 at 17:54
  • @Crashalot The limitation here is mostly theoretical, not technical. The kind of data an SVG image contains just isn’t the same kind of data a JPEG image contains. – Williham Totland Aug 27 '19 at 17:57
  • @WillihamTotland thanks for quick response. understood, just wondering if automated tracing has advanced since 2010. thanks for your help! – Crashalot Aug 27 '19 at 18:10
  • @Crashalot It’s possible that someone has put some kind of AI to it and gotten better results, but I’m not aware of anything specific. – Williham Totland Aug 27 '19 at 18:11

I too was looking for a simple conversion from image to svg - however it is not that easy, but I did find a tool which could take simple images (black and white) and transform them into svg files, also result was much nicer, since it somehow smooth the edges out - however when trying with color images, it did not work. If you want to make simple images and then later tranform into svg, then using an online converter could help you

I used this to convert a couple of simple .png images to .svg
