STL, OBJ, and PLY conversion for 3D printing and CAD work, plus a screen recorder and screenshot tool that's been on our list since day one.
Two additions that do not fit neatly into an existing category are useful enough to get their own writeup: a set of 3D mesh tools for printing and CAD-adjacent work, and a screen recorder with a matching screenshot tool.
If you work with 3D printing or model files, the 3D Mesh Converter converts between STL, OBJ, PLY (ASCII or binary), GLB and 3MF, entirely in your browser with no upload to a third-party service. It also runs size and 3D-printing checks, so you can catch a model that is far too large or too small before it reaches the slicer. A dedicated STL ASCII/Binary converter handles the one conversion people hit most often, and the 3D Mesh Viewer lets you orbit a lit 3D shape with size and printability checks before you commit to anything.
3D Mesh Converter (STL/OBJ/PLY/GLB/3MF) STL ASCII / Binary Converter 3D Mesh ViewerOne honesty note: this covers mesh formats (STL, OBJ, PLY, GLB, 3MF), not STEP or IGES. Those are full CAD-kernel formats that need a real CAD library to parse correctly, and a converter that quietly produces wrong geometry is worse than none.
A short guide saves a lot of round trips:
A workable routine: open the file in the viewer first and look at the dimensions. If a part you designed as 80 mm shows up as 0.08, the exporter used meters, and it is much cheaper to learn that before converting than after printing.
The Screen Recorder captures your whole screen, a single window, or a browser tab, and can optionally record just a selected region. When you finish, you download the recording. The Screenshot Tool is the single-frame sibling: capture, crop, rotate, and draw or highlight on the image before copying or downloading it. Camera Capture takes a photo with your webcam or device camera and lets you crop it.
Screen Recorder Screenshot Tool Camera CaptureBoth capture tools run in your browser, and nothing is uploaded anywhere until you choose to download the result. Your browser will ask which screen, window or tab to share each time, so you stay in control of what is captured.
Occasional use fits within the daily trial usages (10 on Professional Tools such as the 3D Mesh Converter, 2 on Premium Applications such as the Screen Recorder and Screenshot Tool); for a long editing session, see plans and pricing and the full list of professional tools.
