Turn a PNG, JPG or WebP into an SVG: your logo or drawing is traced in black and white, shades of grey or colour. You set the threshold, the number of colours, the smoothness and the speckles, and see the result next to the original.
Good to know
When do you need an SVG instead of a PNG?
A PNG or JPG is made of pixels. Enlarge it and the edges turn jagged or blurry: a logo 300 pixels wide looks terrible on a banner. An SVG is made of lines and shapes and stays sharp at any size, from favicon to shop sign. That is why a printer, an embroiderer or a sign maker asks for a vector file, and why an SVG logo on a website loads faster than the same drawing as a large PNG. If all you have left is the PNG from an old email, this tool traces it: every flat area becomes a shape with smooth edges.
Black and white, shades of grey or colour: which mode do you pick?
Black and white is for a line drawing, a signature, a stamp or a single-colour logo. The threshold decides what turns black; with Automatic the tool finds the value that best separates light from dark. Colour is for a logo or illustration with flat areas: on Automatic the tool finds the colours that are really in it, and with fixed colours you enforce your brand colours. Shades of grey suits a sketch or a pencil drawing. A photo works too, but gives thousands of small shapes and a heavy file: tracing is meant for logos, icons and drawings.
A clean result: smoothness, corners and speckles
Start with the largest and sharpest version of your image you have; a blurry thumbnail will not give a crisp logo. With smoothness you choose between following the pixels closely and calm lines with few points. Sharp corners decides whether a corner stays a point or becomes round, and straight parts are recognised as straight lines, so a triangle gets its tip back. Remove speckles clears dust and noise from a scan. Zoom in up to 8× to compare the original and the result side by side. What you download is a plain SVG with one path per colour, which opens in any drawing program and any browser; for the printer you pick the same drawing as a vector PDF or EPS.
