About Flip3D

Flip3D is a converter, viewer, and (soon) repair toolbox for 3D files. STL, OBJ, GLB, 3MF, PLY today — STEP, FBX, and more on the way. Everything runs in your browser through three.js and WebAssembly. Your files never leave your device.

We built this because the existing converter sites are slow, ad-laden, gate features behind email signups, and upload every file you drop to some server "just in case." The browser is fast enough to do this work locally. So we did.

What you get

5 mesh formats convertible to each other, today
A unified 3D viewer with orbit, zoom, and model stats
One-click sample files so you can try the tool without finding a 3D file first
Dedicated landing pages for every conversion direction
A growing reference library — start with STL vs OBJ vs 3MF vs GLB vs PLY

What's coming

We're building in public. The 12-week roadmap is on GitHub. Highlights:

Bambu 3MF ↔ Prusa 3MF converter (the cross-vendor pain point)
G-code simulator for previewing 3D-print toolpaths
STL repair (non-manifold edges, holes, self-intersections)
Embeddable viewer iframe for blogs and documentation
STEP / FBX / IGES support for CAD interchange

How it's built

Next.js + Tailwind CSS for the UI. three.js for parsing, viewing, and exporting meshes. JSZip for 3MF packaging. Cloudflare Pages for static hosting at the edge. All client-side; the server's only job is to send you the HTML and JS.

Free, forever

No signup, no email capture, no premium tier locked behind a paywall. If we ever add anything paid, it will be additional — every tool that's free today stays free.
