Who builds ilove3d

What it is

32 3D tools that run inside the browser: open a model and measure it, convert between formats, repair a broken mesh, lighten it, and build printable pieces from scratch — vases, lamps, boxes, hose adapters, star maps. All free, none of them ask you to sign up. It started as a dental STL and PLY viewer, and that tool is still the specialized vertical of the set.

Why your files never leave your machine

Because there is no server to upload them to. Every tool runs on WebGL and WebAssembly inside the tab: the file is read from disk into browser memory, processed there, and the result downloads straight back. You can check this yourself by opening the browser's network panel while using any tool — you will not see an upload, because there isn't one. The single exception is stated plainly: the AI features send the text you type, never the model and never the filename.

Why it's free

No accounts, no paid tier, no file limits, no watermark. Serving the site is cheap precisely because the processing happens on your machine and not on a server of mine: what gets sent is a page, not your geometry. It is funded as a personal project. If that ever changes, it will be said here before anywhere else.

What it's built with

Three.js for everything 3D, except the DICOM viewer, which uses Cornerstone3D. Next.js sits on top. The generators build watertight geometry by construction, with no boolean operations, and each one has a signed-volume and edge test that runs outside the browser.
