Vectorising a logo means turning it from pixels into mathematical curves so it stays sharp at every size. But in practice, when do you really need to do it, and when does a free tool like Contour do the job? Here are six situations where it helps, and the ones where it's better to look elsewhere.
Situation 1: all you have is a small JPG of your logo
This is the most common case: a logo grabbed from a website, an email signature or an old invoice. It's small, blurry, sometimes surrounded by a white background. As soon as you enlarge it, it falls apart. Contour rebuilds the outlines from those pixels and gives you back a crisp SVG.
Here, a 300-pixel JPG (left) and the SVG Contour made from it (right), displayed at the same size by your browser. The difference is clear on the edges.
Situation 2: your logo comes from an AI generator
Image generators produce pixelated files, never real vector files (see why AI logos are blurry (in French)). Contour lets you start again from a clean base, as long as the original drawing is simple and made of flat colours. If the result matters, compare it with manual vectorisation (in French).
Situation 3: signage, textiles or print
The printer, embroiderer or sign maker asks for “a vector file”. A JPG or PNG, even a large one, doesn't always suit them. Contour exports to SVG and PDF, two formats they can open. Always check the result: see a logo's file formats (in French).
Situation 4: laser cutting, Cricut, vinyl
Cutting machines don't read coloured surfaces: they follow lines. For that, Contour offers the Cut and engrave mode: each edge is traced only once, as a thin line, which avoids double passes. DXF, the standard for cutting machines, is exported in millimetres, with one layer per colour.
Situation 5: your website
An SVG logo is light, sharp on high-definition screens and adapts to any size without multiple files. The SVG in the example above weighs 2 KB, against 48 KB for the same logo as a 1,200-pixel PNG. To go further, read the advantages and pitfalls of SVG.
Situation 6: editing the logo in Illustrator, Inkscape or Figma
Contour exports solid shapes per colour, which open in Illustrator, Inkscape and Figma. You can then change a shade, delete an element or move points. An automatic trace isn't always as economical with points as a hand-drawn design: allow for a little clean-up if the logo needs heavy editing.
What about privacy?
Contour doesn't send your image: the computing happens in your browser. For a logo that isn't public yet, that's a real argument.
Contour, manual vectorisation or another tool: which to choose?
| Your need | Better suited |
| A quick fix, a test, a base to start from | Contour |
| Laser cutting, vinyl, engraving | Contour (cut mode) |
| Signage, large-format print, a full brand guide | Manual vectorisation |
| A highly detailed logo, with text, gradients or textures | Manual vectorisation |
Five tips for a good result
- Start from the best image possible: the largest, the least compressed.
- Prefer a plain background. If needed, remove it in the Background panel.
- Keep few colours. A logo in flat colours gives a cleaner trace.
- Use the Compare button before downloading.
- Open the file in your software and check the angles and curves before sending it to the printer.
Frequently asked questions about using Contour
When should I use Contour rather than a designer?
For a quick fix, a test or a clean base from a simple, flat-colour logo. For signage, large-format print or a full brand guide, a manual trace is better.
Can Contour vectorise a logo that contains text?
Yes, the letters are traced as shapes. They are no longer editable characters: for clean text, the original font or manual vectorisation is preferable.
Does Contour's DXF work with my cutting machine?
The DXF is exported in millimetres, with one layer per colour, and most cutting software can open it. Always check the scale in your machine's software before cutting.
Do I need an account to use Contour?
No. The tool is free, needs no account and works in your browser.
My take as a designer
My clients often wonder whether their logo is “good enough” for the printer. In most cases, the answer comes down to one question: is the file made of pixels or of curves? A tool like Contour lets you answer quickly and make do at no cost, before deciding whether a manual trace is worth the investment.
A vector file isn't a luxury: it's the minimum for your logo to live everywhere.
To sum up
Contour helps in six situations: small JPG, AI logo, print, cutting, website and editing.
It is less suited to highly detailed logos or to signage and full brand-guide projects.
Try it first, then have what must be flawless traced by hand.
