PNG to STL

Your PNG turned into a part

A PNG with a transparent background already holds the shape's outline: the tool detects it, turns it into a silhouette with thickness and gives you an STL. That's how you get logos for a shop entrance, signs, ornaments, magnets, bookmarks or pieces to glue on a card.

If your image is a JPG or a PNG with a background, it works the same when the background is plain and a different color from the shape: move the threshold until the preview shows only what you want. For photos with a busy background, the "Remove the photo's background" button does it for you.

Silhouette, plate or relief

Silhouette: just the cut-out shape, at the thickness you choose. That's the usual choice for a logo.

Silhouette with a plate: if your logo has letters or parts that don't touch, turn on "Join everything with a plate underneath" and it comes out as one piece. With a single-color printer you can change filament where the plate ends to get it in two colors.

Relief or lithophane: if your PNG is a photo or a shaded drawing, those modes turn brightness into height. You'll find them under "What do you want to make?".

Which PNG works best

The best ones have high contrast and well-defined shapes: flat logos, icons, bold lettering, thick line drawings. Strokes thinner than 0.8 mm can't be printed with a standard nozzle; the tool warns you and you can raise the smoothing or make the part bigger.

Your image isn't uploaded to any server: everything is calculated in your browser, so you can convert clients' logos with peace of mind.

Printing tips

• Thickness: 3 to 5 mm for wall or desk pieces; 2 mm is enough for ornaments or magnets.
• Material: PLA works for almost everything; PETG if it will sit in the sun.
• For a two-color logo: turn on the plate, download the STL and add a filament change right where the shape starts.
• If your logo has very thin lettering, make it bigger or raise the smoothing before printing.
