Vectorizer is a web service that turns raster images into scalable SVG vector files. It accepts up to 20 images in one upload, then provides individual downloads through thumbnails or a ZIP archive. No account or software installation is required, and the service works through the internet, including on mobile phones. Conversion usually takes a few seconds, depending on image size and complexity. The site describes uses in visual design, advertising products, plotters, machine tools, and computer-aided design, with applications for artists working from sketches and engineers handling drawings, plans, or technical documents. Uploaded data and generated files remain for no more than one hour before permanent deletion. Personal and commercial use is permitted, but integrating the service into applications is prohibited. Vectorizer may analyze request metadata to improve the service. The free plan costs nothing.
