TL;DR
- Make it Scalable: Turn a blurry logo into an infinite-resolution vector.
- Tracing Engine: Automatically detects shapes and contours.
- Best Use Case: Simple logos, line art, icons, and high-contrast graphics. Not photos.
Bitmap vs Vector
- Bitmap (Raster): Made of a fixed grid of pixels (JPEG, PNG). If you zoom in, it gets blocky.
- Vector (SVG): Made of mathematical paths (lines, curves). It is resolution-independent. You can print it on a business card or a billboard, and it will be equally sharp.
When to Vectorize
This tool is a lifesaver when:
- Lost Source Files: You have the old company logo on a website but lost the original
.aior.epsfile. - Sketch to Digital: You drew a line drawing on paper, scanned it, and want to turn it into a clean digital graphic.
- Icon Work: You need to simplify a graphic for use in web design or laser cutting/plotters.
Limitations of Tracing
“Vectorizing” is not magic capability.
- Photos: Photographs are continuous tones. Vectorizing a sunset results in a huge, heavy file made of thousands of weird blobs. Do not use this for photos.
- Text: The tracer “sees” shapes, not letters. It will trace the outline of the letter “A”, but it won’t be editable text anymore. It’s just a shape that looks like an “A”.
Adjusting the Output
- Colors: Reducing the number of colors simplifies the image. For a logo, try setting this to 2 or 3.
- Smoothing: Removes the “jitter” from hand-drawn lines.
- Threshold: For Black/White tracing, this decides which gray pixels become black and which become white.
FAQ
Why is my SVG file size huge?
If you trace a complex image (like a photo) details, the SVG will contain thousands of path points. SVG is only efficient for simple geometric shapes.
Can I edit the result?
Yes! The output is a standard .svg file. You can open it in Adobe Illustrator, Inkscape, or Figma to fine-tune the nodes and curves.
