Photo Texture Workbench

Photo Texture Workbench

For game artists and texture makers: straighten a four-corner area of a flat surface in your photo into a PNG texture, and save the project to continue editing later.

Open a JPEG or PNG and place four corners around a flat surface. The tool straightens the selection's perspective into the output proportions you choose. Set the width and height, adjust exposure, contrast and saturation, then export one PNG texture.

Example: a public-domain stone-wall photo and a 480 × 320 export with a four-corner selection and colour adjustments. The tool resamples the photo; it does not create new surface detail.

Keep your edits

• Save a JSON project containing the original photo, corner positions, output size and adjustments. Open it later to continue editing.
• Replace a photo while keeping the relative corner positions, size and adjustments, or start fresh with reset settings.
• Undo and redo edits during the current session, including photo replacement.
• Use the 2 × 2 tile preview to inspect repeated edges.

What you get

A ZIP with the local browser tool, its guide and two public-domain sample photos. Extract the whole ZIP and open index.html in a desktop Chromium browser. No server, account or internet connection is needed to use the tool. Your photos are processed locally in your browser without uploading them.

Version 1.0.0 was tested by AI agents in desktop Chromium on Linux. Other browser engines and native Windows or macOS browser sessions have not been tested.

Limits

One photo and one four-corner selection at a time. JPEG and still PNG input, up to 20 MiB and 24 megapixels; output up to 2048 pixels per side. It has no atlas packing, batch export, seam generation or lens correction. You choose the intended proportions: the corners do not reveal the surface's physical aspect ratio. Shadows, blur and uneven surfaces remain part of your photo.

Save before closing: there is no automatic save. Project files contain your original photo, so share them only when intended. Saved projects retain the current edit state, without session undo history. Exporting a PNG does not save the project.

Licence

Use and modify the tool for personal or commercial work. You may sell textures you make when you have the necessary rights to the source photos. You may not resell or redistribute the tool itself. The included public-domain photos have their own permissions, listed in samples/LICENSES.md.
