Five Steps to Smooth out Bitmap Line Art

Step 1. Import your image

Start Super Vectorizer and import the bitmap line art into the preview pane. You may use Mode 1 or Mode 2 to vectorize line art, but we do not suggest using Line Mode, because it treats the line as a filled shape rather than a thin stroke. Mode 2 creates fewer regions than Mode 1, so it is usually the better choice for line drawings.

Step 2. Reduce color number

Lower the color count so near-identical tones merge. This removes the speckled noise a scanner leaves behind and turns a ragged bitmap into a few solid regions before tracing.

Step 3. Enhance edge

Apply the edge-enhancement step to sharpen and smooth the traced outline. Lines that were broken or fuzzy in the bitmap become continuous, crisp vector strokes that stay sharp at any zoom level.

Step 4. Remove small regions

Use the Remove Small Regions control to delete isolated specks and scanning artifacts. This is the final cleanup that keeps the exported artwork free of dust and noise.

Step 5. Export your result

When the line art looks clean, click Export to save it as SVG, AI, DXF or PDF on Mac or Windows. The finished file opens in Adobe Illustrator, a CAD application, or a cutting-machine workflow.
