API access
The conversion engine is a set of ES modules with no server dependency, so it can run in your own page or in a worker. If you want it behind an HTTP API instead, that is a server-rendered deployment and is priced per conversion rather than per seat.
White label
The converter can be embedded with your own styling and without our branding. The machine-format correctness is the part worth licensing: units, cut order, kerf and the checks, rather than the tracing, which several libraries do adequately.
Volume
In-browser conversion costs us nothing per file, so volume pricing is about support and guarantees rather than compute. Tell us what you need to be true and we will quote against that.
