Engravo

Engravo is a browser-based image editor built specifically for laser engraving. Most engraving software is Windows-only, hasn't been updated in years, and has the UX of a 2003 shareware tool. Engravo runs anywhere, looks modern, and has the processing power to prepare images the way engravers actually need them. ### Tools included (20+) **Basic operations** Grayscale conversion · Resize · Crop · Sharpen · Brightness / contrast / saturation **Advanced tools** - **Text overlay** — add custom text with font, size, color, and position controls - **Shape masking** — apply circular, rectangular, or elliptical masks - **Image slicer** — split large images into a grid for multi-section engraving jobs - **Puzzle generator** — create laser-cuttable puzzle pieces with adjustable piece count and corner radius **AI & effects** - **Background removal** — automatic edge-detection-based background removal - **Cartoonize** — cartoon-style effect with edge detection and color quantization, great for stylized engravings - **AI upscale** — 2x or 4x resolution enhancement for low-res source images - **Vectorize (SVG)** — convert raster images to clean SVG vector output for laser cutting - **Depth map generation** — create depth maps for 3D engraving with adjustable detail levels ### How it works Upload an image. Pick your tools from the Basic, Advanced, or Effects tabs. Adjust parameters. Apply. Undo/redo as needed. Download when ready. Full non-destructive editing history throughout. ### Credits system AI-powered features (background removal, upscaling, depth maps) consume credits. Free accounts get 50 credits on signup. Subscription plans and one-time credit packs are available via Stripe. ### Who it's for - Hobbyist laser engravers who want better image prep without expensive desktop software - Small shops that need a fast, browser-based tool for client jobs - Makerspaces and workshops looking for a shared, no-install solution - Anyone engraving on wood, acrylic, leather, or metal who needs consistent, clean output ### Stack Next.js 15 · TypeScript · Clerk · Stripe · Drizzle ORM · Neon · Sharp · Cloudinary · node-canvas · Potrace · Tailwind CSS v4

Built with Claude Code for a niche that has almost no good software: preparing images for laser engravers. Most engraving software is Windows-only, outdated, and awful UX. Engravo runs in the browser. Sharp handles the heavy image processing server-side. The AI features — background removal and depth map generation — give engravers capabilities that normally require expensive desktop software. A credits system handles the AI compute cost. Cloudinary manages image storage and transformations.

Used Cursor to build the image processing pipeline first, then layered the UI on top. The 20+ tool implementations were each built as isolated modules. The hardest part was getting the depth map and halftone outputs to produce engrave-ready results — required iterating on the Sharp processing parameters extensively. Stripe credits system and Drizzle schema were AI-assisted end to end.
