Serialising Canvas Paths as JSON

Canvas drawing commands are procedural and transient — there is no built-in way to serialise a Canvas path to a data format. This tool converts Canvas API drawing code into a JSON array of command objects that can be stored, transmitted, and replayed.

Real-World Examples & Use Cases

Drawing Storage

Frequently Asked Questions

Can I replay the JSON as Canvas drawing commands?▼

Yes. The JSON format is designed for round-tripping: each object has a type (moveTo, lineTo, etc.) and args array matching the Canvas API call.
