Lithophane Maker

About

🪝 Lithophane Maker: Image to STL turns any photo into a printable 3D lithophane, right inside Chrome

Lithophane Maker: Image to STL is a browser extension that reads the brightness of every pixel in a picture and turns it into a heightmap you can print in 3D. Drop in a photo of a face, a pet, or a logo, and get back a lithophane that glows with the picture when a light sits behind it. No account, no install, no upload: it runs on your device.

🚀 Quick Start
1. Add to Chrome and pin the icon
2. Open the extension and drop in an image, or right click any picture on a web page
3. Adjust shape, size, and thickness on your lithophane
4. Download the STL and send it to your slicer

Why Makers Pick This Lithophane Maker
1️⃣ Right click any image on any web page and choose "Make lithophane" to capture it straight into the tool, no saving files first
2️⃣ A real image to stl converter that reads grayscale luminance, not a guess from an AI model
3️⃣ Flat panels or curved shades, concave or convex, with a diameter control for lamp shades
4️⃣ A live crop box you can drag and resize, plus rotate 90 degrees and flip horizontal or vertical
5️⃣ Brightness, contrast, and a positive or negative toggle to fix a dark photo before you print
6️⃣ Min and max thickness sliders, so your lithophane reads right: thin spots let light through and dark spots stay solid
7️⃣ An optional raised frame, plus draft, standard, or high resolution with an estimated file size

📸 From Photo to Backlit Panel
This lithophane maker keeps the whole image to stl converter pipeline in one tab: it doubles as a plain stl maker for a quick relief, or an image to color stl step for a full color photo. Watch the 3d preview light up on canvas with its own backlight, and adjust the tone until the shadows and highlights read the way a real lithophane 3d print should. Smoothing softens noisy phone photos so the surface prints clean, not grainy.

🎁 Built for Gift Makers and Small Shops
For a gift maker, this is the fastest way to turn a couple into 3d printed lithophane wall art. Etsy sellers can batch a photo to stl job, hobbyists get a quick color lithophane test print, and anyone building a lamp or night light can size a curved panel to fit a bulb.

▸ Works on jpg, png, webp, and gif images
▸ Aspect ratio presets plus manual width and height with a lock
▸ Exports a clean binary file for your lithophane, ready to slice
▸ Side panel or full tab, fully offline, nothing ever leaves your browser

🖱️ The Right Click Edge
- No other picture to stl tool, web or desktop, can turn an image already open on a page into a lithophane without saving it first
- Browsing a photo site or a personal album, right click and send it straight into the lithophane generator
- Works like a screenshot tool, except the output is a printable stl instead of a png
- Skips the download, rename, re-upload cycle that every other png to stl converter still makes you do

💎 Good to Know
🔧 A thinner minimum thickness gives more contrast between light and dark areas
📎 A wider frame keeps the panel from warping on the bed
🖨️ This extension's stl opens cleanly in Cura, PrusaSlicer, and Bambu Studio, so bambu lithophane fans go straight from browser to print
🔁 Beyond lithophanes, run it as a depth map generator, a 3d print from picture step, or convert to stl
🖼️ Turn png into 3d relief art, a logo to stl badge, a jpg to stl ornament blank, or a plain png to 3d model

❓ FAQ

What is a lithophane and why does thickness matter?
It is a thin panel, sometimes typed lithopane, where the picture only shows up backlit. Thin areas pass light, thick stays dark, so the min and max sliders set the right thickness for a lithophane print.

Can I capture an image already open on a website?
Yes. Right click the picture and pick "Make lithophane" from the menu, no saving or re uploading first.

Is this an image to lithophane converter for old family photos too?
Yes. Drop in a scan or a phone photo of any print and turn it into a backlit heightmap panel.

Does it upload my photos anywhere?
No. Every photo to stl conversion runs locally in your browser, fully offline, so your lithophane never leaves your device.

Will it work with my slicer?
Yes. Your lithophane exports as a standard binary stl that opens in Cura, PrusaSlicer, Bambu Studio, and other common slicers.

Can I make a curved lithophane for a lamp shade?
Yes. Switch to the curve shape, pick concave or convex, and set a diameter to fit a lamp or night light base.

Is it really free to use?
Yes, the core png to stl, jpg to stl, and jpeg to stl workflow is free, with no account required. It also works as a plain png to 3d model or turn png into 3d step for pure relief art.
