User-visible changes to the converter, format support and documentation. The methodology page explains how the claims on this site are checked.

9 November 2026

Added a methodology and data page documenting the engines, presets and format sources.
Added a references block to every conversion page, linking the format specification and the engine documentation used for that path.
The homepage converter matrix now links all 35 dedicated conversion pages instead of routing six of them through query strings.
Added reciprocal hreflang annotations to the English STEP to STL page so the eight language versions form a complete cluster.
Content Security Policy updated to allow Cloudflare Web Analytics, a cookieless page-view counter.

Added dedicated pages for CAD, DAE, glTF, IFC to OBJ, OBJ to 3MF, PLY and STL to GLB paths.
Reworked all conversion pages onto the light teal theme; fixed mobile tap targets and horizontal overflow.
Published the Windows app page, the seven localised homepages and the localised STEP to STL pages.
Wrote llms.txt with the verified format counts, presets and limitations.

Site launched: a browser-only converter reading 28 formats and writing 8, with a full-screen 3D preview.
