Open Visio files without Visio. Drop a .vsdx below — it renders right here in your browser, and the file is never uploaded.

LayerBack turns diagram images and PDFs into fully editable VSDX files — native shapes, glued connectors, real text.
Drop the .vsdx file on this page. It is parsed and rendered entirely in your browser — no Microsoft Visio, no account, and the file is never uploaded to a server.
VSDX is the XML-based file format used by Microsoft Visio since 2013. It stores diagram pages, shapes, connectors, and text in a ZIP-packaged XML structure — which is why it can be read outside of Visio.
Yes. The viewer is a full diagram editor — move shapes, change text, then export from the Diagram menu as an image, PDF, or draw.io file.
No. The viewer runs completely client-side: the VSDX is unpacked and rendered by JavaScript in your browser tab. Close the tab and it is gone.
That is exactly what LayerBack does — upload a diagram image (or PDF page) and get back a fully editable VSDX with native shapes and connectors.
