Why Flip3D
Built different from the bloated converter sites out there.
100% Local Processing
Your files never leave your browser. We use WebAssembly to convert everything client-side. No upload server, no privacy risk.
Always Free, No Signup
No account, no email, no credit card. Open every tool, drop a file, get your output. No ads in your face either.
Built for Makers
Bambu Lab, Prusa, Anycubic, Creality — we're fixing the cross-vendor compatibility headaches no one else will.
