Texture any STL, instantly.

Yes. This is one of the main reasons people use TextureAnySTL. Flat, smooth walls printed on an FDM machine almost always show visible layer lines (the horizontal banding from each printed layer). Even a shallow surface texture (0.2–0.4 mm depth) breaks up that banding visually so the eye reads the surface as a finished, intentional pattern instead of a stack of layers. It works on PLA, PETG, ABS and resin, on any layer height, and removes the need for sanding, primer or filler. A subtle texture like Noise, Lines, or Woven works on almost any model; geometric patterns like Hex or Diamonds add character to flat panels.

No, never. TextureAnySTL is a static website with no backend. Your STL is opened and processed entirely inside your browser tab using JavaScript and WebGL. No data is ever sent to any server. You can verify this by opening DevTools → Network while processing a file; you'll see zero outbound requests carrying your model data. You can even disconnect your internet after the page loads and everything still works.

Depth controls how far the texture is pushed into or out of the model surface, in millimetres. A positive value embosses (raises the pattern above the surface) and a negative value engraves (cuts the pattern into the surface). Typical values are 0.2–0.6 mm for emboss and −0.2 to −0.5 mm for engrave. Double-click the slider to reset to the default.

Tile scale is how large one full repeat of the texture is on the printed model, in millimetres. At 20 mm, one tile covers a 20 × 20 mm area. Smaller values make the pattern denser; larger values make it coarser. Double-click the slider to reset to 20 mm.

Yes. The fastest way is to hold Ctrl (or Cmd on Mac) while clicking to add faces to the current selection, then apply the texture once to all of them. You can also apply, click a new face, and apply again; each apply is baked into the model geometry. The Undo button steps back one apply at a time. Export any time; the exported STL includes all applied textures.

A few that save time:

• Double-click a face to instantly apply the currently selected texture, no need to hit Apply.
• Ctrl+Click on faces to add them to the current selection (Cmd on Mac).
• Esc clears the current face selection.
• Ctrl+Z undoes the last texture apply (Cmd+Z on Mac).
• Click the rotate pin that appears on each selected flat face to rotate the texture preview by 90° steps. Each face has its own pin, so you can rotate textures independently per face. Repeated clicks cycle 0° → 90° → 180° → 270° → 0°. The baked result matches exactly what you see in the preview.
• Double-click any slider (Depth, Tile scale, Brush size) to reset it to its default value.
• Right-drag in the 3D viewer pans the camera; scroll zooms.
• The view cube in the top-right of the viewer snaps to standard orthographic views.

There are 20+ built-in presets: geometric patterns (hexagons, diamonds, boxes, Aztec…), organic shapes (bubbles, clouds, autumn leaves…), and material-based heightmaps (woven knit, aluminium tread plate…). You can also upload your own PNG or SVG image as a custom texture.

Yes. Click Upload your own… in the texture panel and choose any PNG, JPG, or SVG file. The image is used as a greyscale heightmap: lighter areas become raised (emboss) or deeper (engrave), darker areas stay flat. For best results use a seamlessly tiling greyscale image.

Yes. The exported file is a standard binary STL with a closed, watertight mesh. It has been tested with Bambu Studio, PrusaSlicer, Cura, and Chitubox. Import it the same way you would any other STL. No special settings required.
