Raster-to-SVG Preparation and Quality Checks Cheat Sheet by EthanLeeSVG

Start with artwork you own or have permission to convert.
Use a clean, sharp source rather than a thumbnail or screenshot of a screen­shot.
Logos, icons and flat illust­rations are easier starting points than detailed photog­raphs.
Keep a copy of the original; tracing is an approx­ima­tion, not a recovery of the original vector design.

Crop unused margins so you can judge the artwork clearly.
Keep the original propor­tions when resizing. Enlarging a small raster does not restore missing detail.
Avoid repeatedly exporting JPEG: compre­ssion can introduce edge artifacts.
Check fine lines, small text and transp­arent edges before tracing. Use the highes­t-q­uality source available.

Begin with the default trace and compare it with the source.
Increase color detail only when meaningful shapes or colors are missing.
Adjust smoothing while watching corners and thin strokes.
Change one control, compare again, and keep the version that best preserves the intended shape.
More detail can also mean more paths and a larger file.

Compare the source and trace at the intended display size.
Zoom in to inspect corners, gaps, thin strokes and edge noise.
Check both small and large shapes; a smooth outline can still lose an interior detail.
Do not assume the SVG will be smaller than the source.
For cutting or manufa­ctu­ring, validate the paths separately in the destin­ation software.

The .svg extension alone does not prove an image was traced: SVG can contain embedded raster images.
Open the result in a compatible vector editor and inspect its objects.
Confirm the artwork remains legible at the size you actually need.
Keep the raster source and the chosen tracing settings with the exported result.
A path-based result may still need manual cleanup, especially for text or intricate artwork.

Example tool: JPG to SVG (the contri­butor's project).
Use a JPG, PNG or still WebP image; crop or resize if needed, then trace and compare.
The example tool processes images locally in the browser and handles one image at a time.
Its output contains SVG paths; it does not guarantee a perfect match or ready-­to-cut geometry.
Apply the quality checks above before reusing any traced output.
