Printable Kit QA Studio

Make print-ready paint-by-number worksheets

Tap a built-in sample for a print-ready worksheet in one click — or upload your own photo (experimental). PaintGrid checks for tiny regions, blank labels, and hard-to-tell-apart colors before you export. Everything runs in your browser.

Drop a photo — experimental input

or click to browse — PNG, JPG, or WEBP, up to 25 MB. Works best with simple, high-contrast images; a built-in sample is the quickest way in.

Processed locally in your browser — the core generator never uploads your photo.

Example photos

Settings

Quick preset

Apply a tuned bundle of settings. You can still tweak any control after.

Number of colors

S = Studio · P = Pro — see Pricing for paid plans.

Fewer colors paint faster; more colors capture detail. Free max 8 · Studio 24 · Pro 32

Region detail

Balanced regions — the default.

Artwork size

The finished painting's size. It's scaled to fit your paper — or tiled across pages in Poster mode.

Paper size

Free prints at A4 or US Letter. Larger print sizes are a planned Studio Export Pass feature.

The physical paper or media you plan to print on.

Orientation

Advanced▸

Optional fine-tuning — your Quick preset above already sets sensible defaults for everything here.

Print readability

How the printed sheet looks and how much ink it needs. Your Quick preset already sets these for a readable, fully-numbered result.

Label density

Labels readable regions; may match Sparse on simple images.

Edge smoothness

Smoothed, paint-friendly curves. Recommended for most prints.

Line thickness — 1.0 px

Number size — 9 pt

Show faint cell grid

White halo behind numbers

Low ink mode

Lighter fills to save ink — also turns off the cell grid and number halo.

Image processing

How the photo is simplified into paintable regions. Region detail above is the primary control — these are secondary tweaks.

Detail level — 50%

Fine-tune on top of Region detail. Higher keeps fine features; lower simplifies into broader regions.

Output style

An extra cell-size bias on top of Region detail.

Preserve fine lines

Legacy behavior. Best for posterized or strictly flat artwork.

Merge tiny regions

Absorbs slivers too small to paint into neighboring regions.

Tiny-detail protection

Keeps deliberate small details from being merged away.

Kid-friendly mode

Forces larger regions that are easier for young painters.

Grayscale preview

Poster & multi-page output

Split the artwork across several sheets. Cut lines and assembly marks appear once Poster mode is on.

Poster mode (multi-page)Studio

Classroom Pack splitsPro

A PDF with one numbered section per student.

Export

Applied to the PDF when you download it.

Legend placement

Export watermark

Pick how the output assigns its colors.

Auto palette — colors will be extracted from the image and labeled Generated 1…N.

Starter palettes & your own paints— optional constraint▸

Starter palettes

Optional constraint — picking a palette switches to Use selected paints.

Your own paints

Optional — add your own paint hex codes to map output to colors you own.

Export

Free preview and exports include a PaintGrid Studio watermark. Watermark-free export is a planned paid feature.

Upload an image and wait for the preview to generate, then export.

Download

PDF — a digital reference at this coverage (many regions would print blank): the numbered design with optional cut and registration marks, plus a color legend.

Numbered PNG is the outline as one image; Color PNG is a color reference of the result.

Legend CSV is the color table for spreadsheets; Shopping list is the paints to buy, as text.

Print layoutSingle artwork page

Your 11 × 14 in artwork is larger than US Letter — it will be scaled to about 69% (≈ 7.6 × 9.7 in) to fit one sheet. To print closer to actual size, switch on Poster mode or choose a larger Paper size.

1 artwork page + 1 legend page = 2 PDF pages.

Color legend will appear here once you generate an output.
