How to use

Check supported input/output details and follow the tool steps before exporting.

01

Pick a resolution from 256×256 up to 8192×8192.

02

Set cells per edge and micro-grid density.

03

Choose a colour palette and whether to draw cell borders.

04

Choose a label style — sequential numbers, spreadsheet letters, or column,row coordinates.

05

Choose your model to see the checker on it in 3D, then download the PNG.

✨

In-browser uv checker map generation

  • Runs entirely in your browser — nothing is uploaded, and no upload is needed to start.
  • Resolutions up to 8192×8192.
  • Deterministic output — identical settings give an identical map.
  • Labelled cells make rotation and mirroring obvious.
  • Colour-blind-safe palette included.
  • Continues straight into UV layout inspection against your actual model.
🎯

Test uv unwraps with a labelled checker map

  • Spot texture stretching on a character model.
  • Confirm island rotation and mirroring with labelled cells.
  • Judge texel density consistency across a scene.
  • Produce a print-grade 8K reference checker.
  • Test a UV unwrap before painting any real textures.

Control the grid

Set the output resolution, cells per edge, and an optional micro-grid drawn inside each cell as fine lines. Cell borders can be turned off for a cleaner reference.

Output is deterministic: the same settings always produce the same pixels, which is what makes a checker usable as a reference at all.

Pick a palette and labels

The classic multi-colour grid is easiest for spotting rotation and mirroring. Neutral grey stays out of the way when you are judging texel density. High contrast maximises seam visibility, and a colour-blind-safe blue/orange pair is included.

Labels can be sequential numbers, spreadsheet-style letters, or column,row coordinates — all of which make a mirrored or rotated island immediately obvious once the map is on a surface.

Check it against the real model

Switch the task to UV check and choose a glTF or GLB, and the toolkit draws that model's actual UV islands over the checker you just generated.

It also reports island count, how much of the 0–1 square is used, triangles outside it, and overlapping island pairs — the things a checker map alone cannot tell you.

FAQ

Common questions.

Have more questions? Reach out via our contact page and we will respond within 24 hours.

Do my files upload to a server?

No. The checker map is generated in your browser and nothing is sent to a server.

What is the maximum resolution?

8192×8192.

Is the output deterministic?

Yes. The same settings always produce a byte-identical map, so you can compare two renders directly.

Can I see the checker on my model?

Yes. Choose a glTF or GLB model and switch the preview to 3D to see the checker on it, or use UV check to draw its UV islands over the map.

Which palette should I use?

The classic colour grid is easiest for spotting rotation and mirroring; neutral grey stays out of the way when judging texel density; there is also a colour-blind-safe pair.
