Vectorizer.io

Turning a pixel-based image into a scalable vector file is the whole job of Vectorizer.io, an online raster to vector converter that runs in the browser.

You upload an image, and the site gives back a vector version in one of several supported formats, so a logo or illustration can be resized without going blurry.

There is also an API category attached to the tool, which suggests it can be used from code as well as through the page.

Pricing is where you should read carefully.

Vectorizer.io is listed as free, but the free part is a limited set of credits meant for evaluation, and a Fair Use Policy caps how many downloads you can make.

Commercial use requires a purchase.

You do not need a subscription, since access passes are an option instead.

One practical catch: mobile devices may not fully support vector formats, so you will likely want a desktop to open and check the results.

Vectorizer.io suits quick conversions for designers and developers who want to test the output before paying anything.
