JSON Canvas Viewer — See .canvas Files in Your Browser
🔒 Your .canvas is parsed and rendered in your browser and is never uploaded.
A JSON Canvas viewer that does one thing well: open a .canvas file and show you the board immediately, full size, in your browser. There is no upload step and no account — the JSON is parsed on your own device. JSON Canvas is the open format behind Obsidian’s Canvas feature, so a quick standalone viewer is the fastest way to actually look at a board that a teammate sent you or that you found in a Git repository. Text cards keep their Markdown formatting, groups and colors are preserved, and edges are drawn with their arrows and labels. Export to PNG or SVG whenever you want a shareable copy.
How it works
- Choose or drop your
.canvasfile(s). - The board is parsed and drawn instantly — in your browser.
- Export it as a PNG or SVG image. Nothing is uploaded.
FAQ
Can I view several .canvas files at once?
Yes. Select or drop multiple files and each board is parsed and drawn separately, with its own export buttons.
Does the viewer change my file?
No. Viewing is read-only and exact; your original .canvas file is never modified. Exports are generated as brand-new PNG or SVG files.
Does it work on mobile?
Yes, in any modern mobile browser. Very large boards may be limited by your device’s memory when exporting at high resolution.
