From Raster to SVG: Practical Tips for Cleaner, Editable Vector Output

SVG is often treated as a simple export format — click “Export as SVG” and move on.
In reality, SVG quality depends heavily on how the vector is generated, especially when starting from raster images like PNG or JPG.

Over the last months, while working on SVG conversion workflows, I noticed a few recurring issues that designers and developers run into.

1. Why raster-to-SVG conversions often look bad

Most automatic converters try to trace everything:

• noise

• gradients

• shadows

• anti-aliased edges

This results in:

• overly complex paths

• huge file sizes

• SVGs that are hard to edit in Figma

The key insight: clean input matters more than the tracing algorithm itself.

2. Pre-processing before vectorization

Before converting to SVG, it helps to:

• remove backgrounds

• increase contrast

• simplify colors

• isolate the main shapes

Even basic cleanup dramatically improves path quality and makes the final SVG easier to edit or animate.

3. Optimizing SVGs for real use

A usable SVG is not just visually correct — it should also be:

• readable

• editable

• performant on the web

Path simplification, color grouping, and removing unnecessary metadata often matter more than perfect visual fidelity.

4. SVG workflows beyond export

Clean SVGs unlock better workflows:

• easier editing in Figma

• smoother animations

• more predictable scaling

• better handoff to developers

While exploring these problems, I ended up building toSVG, a small web tool focused on producing clean, optimized, editable SVGs from raster images — not just “auto-traced” ones.
