Convert scanned drawings into clean, editable SVG

This page is tuned for scans: pencil sketches, ink drawings, worksheets, and handwritten notes. Scans usually fail for two reasons: uneven lighting and scanner dust. The pipeline here normalizes the image, suppresses background paper texture, removes speckles, and then traces the remaining ink into SVG paths. The goal is an SVG you can actually edit, recolor, and scale without thousands of noisy points.

Scan → SVG: what to fix before tracing

Vectorize scanned drawings and documents into clean SVG. Built for scans with speck removal, smoother curves, and presets that help close tiny gaps.

A scan is not “clean ink on white.” It usually includes shadows, paper grain, faint pencil noise, and random dust that becomes tiny blobs after thresholding. If you trace that directly, you get messy outlines and a huge node count. The clean approach is: normalize the scan, decide what counts as ink, then smooth and simplify the result.

Start with a preset that matches your scan quality. If the preview shows dots everywhere, treat it as a cleanup problem first: increase turd size (speck removal) and raise blur/normalization so the paper texture stops producing edges. If the preview shows broken strokes, switch to an Aggressive preset that seals small gaps, then fine-tune threshold so faint strokes stay connected without turning the background into noise.

Once the drawing is “correct,” reduce node count so editing is sane. Increase curve tolerance until jagged edges become smooth, but stop before corners and intentional angles start rounding off. If you’re exporting for cutting or plotters, fewer nodes also improves performance in cutter software.

Step 1: Remove dust

Increase turd size until isolated dots disappear, without removing intentional tiny marks.

Step 2: Keep strokes connected

Use Aggressive for small breaks, then adjust threshold so faint lines survive.

Step 3: Smooth and simplify

Increase curve tolerance to reduce jaggedness and node count, then stop before shape drift.

Scan cleanup tips

Speckles: increase turd size.
Gaps: lower threshold, raise curve tolerance, and try Turn policy: black.
Thin details disappearing: increase threshold and lower turd size.

If your scan has dots everywhere

Use Speck killer or increase turd size until dust disappears. If dots persist, increase blur/normalization so paper texture stops becoming edges.

If your scan has broken lines

Use Aggressive to close small gaps, then lower threshold slightly until faint strokes reconnect without pulling in background noise.

Uneven scan lighting

If one side looks darker, increase normalization/contrast so the background becomes consistent before tracing.

Pencil is too faint

Lower threshold a bit and use stronger edge settings so light graphite becomes ink without amplifying paper grain.

Paths are too complex

Increase curve tolerance until edits are manageable. Node count matters more than micro-detail for clean SVG line art.
