Raster vs vector: what is the actual difference?
Raster formats such as PNG, JPG and WebP record a colour for every pixel. They are ideal for photos. Their weakness is resolution: stretching a 500 px logo to poster size only makes each pixel bigger.
Vector formats such as SVG, EPS and PDF artwork store instructions instead: "draw a curve from here to there and fill it with #1A73E8." A renderer recalculates those shapes at whatever size is needed, so edges stay crisp on a phone, a 5K monitor or a printed banner.
When you should vectorise
- Logos and icons that must appear at many sizes.
- Line art, signatures and stamps for documents.
- Designs for vinyl cutters, laser engravers and embroidery software, which need paths.
- Simple illustrations you want to recolour or edit shape by shape.
Photos are usually better left as raster images; a traced portrait becomes thousands of blobs.
How to get a clean trace from a PNG
Tracing quality depends mostly on the source: sharp, flat-colour images trace into a few tidy paths, blurry ones into wobbly outlines.
Prepare the source image
- Use the largest version you have. Upscaling a tiny logo first with the image upscaler can smooth the edges the tracer follows.
- Remove a busy or off-white background first with the transparent background tool, then trace the PNG.
- Crop away empty margins so the subject fills the frame.
Choose settings that match the artwork
For a two-tone logo or handwriting, black & white mode is usually perfect. For a brand mark with three or four colours, set the colour count to the number of inks you can see, plus one or two for anti-aliased edges. Raise detail if thin strokes disappear; raise smoothing if curves look lumpy or the file has too many nodes.
Using your SVG on the web, in print and in cutting machines
An SVG from this tool is ordinary XML, so it works almost everywhere. On a website you can reference it with an img tag, set it as a CSS background, or paste the copied code inline to style it with CSS. Because the file contains real paths, you can change a fill colour in any text editor.
Editing and production tips
- Design apps: open the file in Inkscape, Illustrator or Figma to merge shapes, fix a stray node or add text.
- Cricut and Silhouette: each colour group imports as a separate layer, which maps neatly to vinyl colours.
- Print: printers often ask for vector logos; an SVG can be converted to PDF or EPS in most design software.
- File size: fewer colours and more smoothing mean fewer paths and a lighter file for faster pages.
