Edges stay square
Smoothing is off and detail is Fine, so a corner in your artwork becomes a corner in the mesh instead of a rounded ramp.
LOGO TO STL
Logo to STL converter
Extrude a logo into a clean raised emblem. Sharp walls, a flat mounting base, and depth set in millimetres so it fits the part you are branding.
Upload once and a printable relief STL starts building in this browser. Best for logos, portraits, terrain, signs, and lithophanes.
About this converter
A logo has to survive extrusion without losing its geometry, which means no smoothing, the finest sampling available, and a base thick enough to keep a wide plate flat. Those are the settings this page starts from. The result is a solid with vertical walls, a consistent emblem height, and a sealed flat back you can glue, screw, or print directly onto another part.
LOGO TO STL
From image to sliced print in three steps
- 1
Load your image
Drag in a PNG, JPG, or WebP, paste from the clipboard, or start from a built-in sample.
- 2
Set real dimensions
Type the width, height, relief depth, and base thickness in millimetres and watch the mesh rebuild live.
- 3
Check, then download
Read the open-edge and manifold report, then export a binary STL straight into your slicer.
Mounting-ready base
A 1.8mm floor gives a rigid plate that resists warping on a wide emblem and provides a real surface for adhesive or fasteners.
Clean two-colour layer change
Because the emblem sits at one uniform height, a single filament swap at that layer produces a crisp two-tone badge with no manual editing.
Built around prints that actually succeed
Live geometry, not a mockup
Every slider rebuilds the real mesh in a worker thread. What you orbit is the file you download.
Millimetres, not guesswork
Width, height, relief depth, and base thickness are typed in real units, so the plate fits your bed the first time.
Six pre-slice diagnostics
Open edges, non-manifold edges, degenerate faces, triangle count, volume, and bed contact are all reported.
Local by default
Relief, lithophane, viewer, and converter work never leaves the browser. Only AI generation uploads anything.
Five interchange formats
Export binary STL, GLB, glTF, OBJ, or PLY, and convert between them without installing a modelling suite.
Free where it counts
Unlimited local conversion with no watermark, no daily cap, and no account. Credits apply only to AI generation.
Which mode fits your image?
Relief mode extrudes brightness into height. AI mode reconstructs a full closed volume.
| Relief / Lithophane | AI 3D Object | |
|---|---|---|
| Best input | Logos, line art, portraits, terrain, height maps | Product shots, characters, props, toys |
| Output shape | Raised plate with a flat back | Closed volume with a real back and sides |
| Typical wait | Under 3 seconds | 40 seconds to 4 minutes |
| Where it runs | This browser only | Uploaded to the model provider |
| Cost | Free and unlimited | From 8 credits per model |
Made with IMG2STL

Frequently asked questions
How deep should a logo be extruded?
Between 2 and 4mm reads well on a hand-held badge. Thinner than 1mm and the emblem disappears under normal lighting; thicker than 5mm and fine interior details start to look like walls rather than lettering.
My logo has thin lettering. Will it print?
Only if each stroke is wider than roughly two nozzle widths, about 0.8mm on a 0.4mm nozzle. Either scale the whole plate up until the strokes clear that threshold, or thicken the letterforms in your artwork first.
Should I start from PNG or SVG?
SVG whenever you have it, because it is sampled at your target size and keeps curves smooth. A high-resolution PNG with transparency is a close second. Avoid low-resolution screenshots, which carry compression edges into the mesh.
Can I recess the logo instead of raising it?
Yes, enable Invert depth. The emblem then sits below the surrounding plate, which is what a stamp, a mould, or a paint-fill inlay needs.
Can I use this for client work?
Yes. Local conversion adds no watermark and imposes no licence on the output. You do need the rights to the logo itself, and the file never leaves your browser, so confidential brand work stays private.
