Turn Any Photo Into a Carvable 3D Relief — Free, In Your Browser

JACR CNC Studio is an all-in-one browser CAD/CAM/sender — a browser-based 3D relief creator, a full online CAM software suite and G-code generator, and a live Web Serial CNC controller, so you never need a separate GRBL sender. Convert images to 3D relief carvings in minutes — an affordable alternative to desktop suites like Vectric and Carveco — design and preview everything free, then one cheaper-than-cheap membership exports every format and runs your GRBL CNC router over USB. Nothing to install. It all runs right here.

🧊 Unlimited STL files — $5.99 a month
Works in Chrome & Edge · Free sign-up — design everything · Membership $5.99 to export & carve · Your images never leave your computer

🧊 Stop Buying STL Files. Start Making Them.

Etsy shops charge about $5 for a single relief STL file. A JACR membership is $5.99 a month — for UNLIMITED 3D relief carving STLs of your own art, generated from any photo or artwork in minutes — or sculpted and 3D-modeled from scratch right in the browser.

Buy STLs on Etsy?
One file there costs a whole month here. Make your own — exactly the art you want, at exactly your stock size, unlimited.
Sell on Etsy?
This is your production engine. Turn your own artwork into relief STLs and finished carvings as fast as you can list them — a $5.99 tool that builds $5-a-piece inventory.

Make one file and the month has paid for itself.

Start Making Your Own STLs

One Studio. Every Carving Style.

Twelve guided carving styles, a full vector CAM workspace, and live machine control — the tools desktop suites charge hundreds for, free in a tab.

3D relief creator icon

In-App 3D Relief Sculpting

Photo → carvable relief with AI depth and the 🏺 porcelain converter — sculpted and baked directly onto the CNC bed, no external STL software required. Height curve, edge slopes, touch-up pens, true 16-bit depth-map import.

🏗

3D Model & Sculpt in the Browser

Build from 3D templates and shape profiles (domes, ogee, cove), sculpt with brushes and pens, then bake the model straight onto the CNC bed — carve it live or export the STL. No Blender, no ZBrush, no desktop CAD.

V-carve engraving icon

V-Carve & Engraving

Crisp V-bit lettering and line art with WordArt styles, contour tracing and per-text depth control.

Browser CAD/CAM + G-Code Generator

Draw vectors or use the built-in bitmap-to-vector tracing (no third-party tracing tools), stack Profile, Pocket, V-Carve and Drill toolpaths, and generate clean G-code (.nc) for any GRBL machine.

🔌

The PRO Carve — In App

Membership runs the job other senders cannot: roughing bulk-clear with built-in tool swaps — guided pause, spindle parked, auto re-home, position re-verified — streamed live to your GRBL router from Chrome or Edge.

💡

Lithophane Maker

Backlit photo panels with a live glowing preview — dark = thick, bright = thin, ready for translucent stock.

CNC sign maker icon

Signs, Frames & More

Sign Maker, Frame Builder, Light Box silhouettes, Tray & Bowl, Cut-Through stencils, Prism carving, Flatten — all wizard-guided.

📦

Every Export Format 🔒

High-detail STL, bit-modeled STL, 16-bit depth TIFF, PNG and single-bit G-code (no tool swaps — loads in any sender). Design free; membership unlocks every export.

📖

Feeds & Speeds Built In

A real feeds bible drives every recommendation — bits, stepovers, depths — tuned for hobby routers, explained in plain words.

How It Works

From photo to sawdust in three steps — no CAD experience needed.

Upload any image

Or click a Try-It example. The 🏺 porcelain converter turns ordinary photos into ideal relief inputs — or import a true depth map for reference-grade results.

Style your relief

Live sliders for depth, detail, smoothing and background; height curve; edge slopes; pens to touch up anything. What you see is exactly what exports.

Carve it

The Carving Wizard picks the best bit and builds the job. Membership takes it from there: export single-bit G-code for any sender, or run the full pro job — rough pass, safe guided bit swap, fine finish — live on your CNC, right here.
