Manual merge & split controls for paint-by-numbers regions
Auto-generated colour regions aren't always exactly what you want. Merge small or unwanted regions, split areas that are too broad, then preserve those edits in a true vector SVG.
Why region editing matters
Automatic processing sometimes leaves tiny flecks of colour in a smooth area, or lumps two visually distinct areas into one region. Most generators give you a detail slider and nothing else: you either accept the automatic result or start over with different settings. Region editing lets you fix it directly instead.
To be accurate about it: we are not the only tool that can merge segments — Mimi Panda has a segment editor too, though it processes on a server and is paid beyond a couple of conversions a week. What we have not found anywhere else is splitting a region, and free, unlimited region editing that runs on your own machine. Checked September 2026.
How to merge regions
- Generate your template, then switch to the Merge tool in the Refine step.
- Click two adjacent regions to select them.
- Confirm the merge — the regions combine into one, and the colour count updates.
How to split a region
- Switch to the Split tool.
- Click a region that's too large or contains more than one colour you'd like to separate.
- The tool analyses the region's colour variance and proposes a split.
Pair region editing with a vector SVG export so your edits stay crisp at any print size.
