Why your logo falls apart when enlarged
PNG and JPG are fixed grids of pixels. Enlarge one and the device has no extra information to work with, so it duplicates the pixels it already has — edges go jagged and detail turns to mush.
An SVG stores no pixels at all. It stores a mathematical description of paths, shapes and colours, so it is redrawn at any size at the same quality — on a business card or on a billboard.

When you genuinely need a vector file
Not every image needs converting. The practical rule: anything that represents your identity and gets printed at different sizes should be a vector.
Print shops usually reject PNG logos, because nothing guarantees the edges hold up when scaled. They ask for SVG, AI, or a vector PDF.
If all you have is an image of the logo and no source file, the answer is automatic tracing — vectorization, which converts pixels into paths.
Converting at print quality, step by step
Start from the sharpest copy you have. The higher the resolution, the fewer mistakes the tracer makes at the edges. A clean white or transparent background helps.
Then use a tracer that handles multiple colours. We use 12pixa, a free tool that converts images to SVG inside the browser with no upload to any server — which matters when you are handling a client identity that has not been announced yet.
Pick the right preset: logos and lettering need hard edges, illustrations need more simplification. After converting, check the colours and remove the background layer before downloading.

Common mistakes that ruin the result
Starting from a small or heavily compressed image makes the engine trace compression noise instead of real edges, and you get wobbly paths.
Leaving the background in the file adds paths nobody needs, inflates the size, and causes problems in embroidery and cutting.
Vectorising a full photograph produces thousands of paths and a file heavier than the original, for no real gain.
Frequently asked questions
What is the difference between PNG and SVG?
A PNG is fixed pixels and breaks up when enlarged. An SVG is mathematical paths, redrawn at any size with no loss of quality.
Can any image be vectorised?
Logos, lettering and line art with clean edges give the best result. Photographs produce heavy files and imprecise detail.
How large should the image be before converting?
The sharper and larger the source, the more accurate the result. Aim for at least 1000px wide, with a clean background and crisp edges.
