Free 3D and image tools. They run on your device.

The tools on this page run on your own device. There is no upload, no queue and no account. That is the point of them: a file you convert here never reaches a server, so there is nothing for us to store, and nothing for us to see.

The main tool is the 3D model converter. It reads STL, OBJ, GLB, glTF, PLY, FBX and 3MF, writes STL, OBJ, GLB, glTF and PLY, fixes the Z-up to Y-up axis mix-up that leaves converted models lying on their side, and shows the triangle count before you save. If you print, it is a quick STL converter for files that came out of a game or AR pipeline. If you build for the web, it turns CAD exports into GLB.

The STL viewer opens an STL file online without installing anything. It shows the model in 3D with its size in millimetres and inches and its triangle count, so you can check a print file before you slice it. It opens OBJ, GLB, glTF, PLY, FBX and 3MF files too.

For images, the image converter turns PNG into WebP for a website, WebP back into PNG for editing, or JPG into JPEG XL for the smallest files, with a quality setting and a resize menu. The image metadata viewer shows what a picture carries before you share it: EXIF data, the GPS location, serial numbers, and any AI label or Content Credentials. It can strip the personal data and leaves the AI label in place.

Before you print, the DPI calculator tells you how big an image prints at 300, 240 or 150 DPI, or how many pixels a print size needs.

AI generation is a different thing and does run on servers. The generators make images, video and 3D from a prompt or a file, and the 3D generation page explains text-to-3D and image-to-3D. A common path is to generate a mesh there, then bring it back here to convert it for a printer or an engine. The blog has the longer guides, including what to use for AI video now that Sora is winding down and the text to video and image to video tools those guides lean on.
