What is vectorization?

Vectorization is the conversion of raster graphics into vector graphics. Raster images are made of pixels and become pixelated when they are enlarged. Vector graphics store the shapes of an image as mathematical formulas, so they can be scaled to any size without losing quality.

How do I use this service?

You don't have to register. Upload your image (JPG, PNG, WEBP, BMP, TIFF or PDF), choose the output format and click "Start". Then save the resulting file to your computer. Of a PDF, the first page is converted.

Which settings should I choose?

Start with the defaults; if the result isn't right, go back and change one setting.

• Detail: "Low" removes specks and small dots (e.g. dust on a scan) and makes the file smaller; "High" keeps even the finest details.
• Lines: decides which tones become black. Lines missing, e.g. of a pencil sketch? Take "Also light lines". Large areas black, e.g. in a colored image? Take "Only dark lines".
• Corners: "Sharp corners" makes straight lines and sharp corners instead of curves: for logos, technical drawings and pixel art.
• Invert: for light lines on a dark background, e.g. a photo of a chalkboard.

Which tools do you use?

We use the excellent Potrace by Peter Selinger as autotracer.

Does this service support color images?

No, images are converted to black and white. If you need an online autotracer for color images, we recommend www.autotracer.org.
