Cleaner lines for tracing

Prepare your image so TraceLine can capture finer, more stable lines with less noise.

Scale without losing control

Resize up to 4096px to make small details easier to trace—without turning the image into “AI-enhanced” noise.

Made for TraceLine workflow

Export a prepped image, then jump straight into TraceLine for precise line work and adjustments.
