Which export formats are available on Free vs. Pro, where each one runs, and how the watermark works.
| Format | Available to | Runs | Notes |
|---|---|---|---|
| PNG, JPG, SVG | Free (watermarked), Pro | In the browser | |
| JSON, CSV | Free, Pro | In the browser | Never watermarked |
| XLSX | Pro | In the browser | Never watermarked |
| Pro | On the server | ||
| DXF | Pro | On the server | Plant Room Studio only |
| IFC | Pro | On the server | Plant Room Studio only |
Not every tool offers every format. Each tool's own docs are authoritative for its export panel, but as a starting point:
See the tools catalog for the full list of tools and their plans.
This is the most misunderstood part of exporting, so to be plain about it: DXF and IFC export are only available on the Pro plan, and only from Plant Room Studio. No other tool produces these formats.
Guests and Free-plan users get a tiled, diagonal "DRAFT" watermark at low opacity on PNG, JPG, SVG, and PDF exports. This watermarking happens in your browser, not on the server. Upgrading to Pro removes it.
JSON, CSV, and XLSX are never watermarked — there's no visual surface to stamp a watermark onto.
SVG is watermarked, unlike the other browser-side formats. It's a vector image, so a guest or Free-plan SVG export carries the same DRAFT watermark as PNG and JPG. Upgrading to Pro removes it.
We don't claim the watermark is tamper-proof or that it can't be bypassed. It's a visible marker that an export is a draft, not a security control.
Watermarked draft exports are not intended for submittals. And regardless of plan — watermarked or not — the exporting engineer remains responsible for checking the output before it's used. See the Engineering disclaimer.
Exports don't require the document to be saved to your account — they run from whatever is on screen. But an export is a snapshot, not a save: if the work matters, get it into your account too. See Save status & unsaved work.
The calculators also offer Copy share link in their action rail, which puts the current inputs into a URL you can paste to a colleague — no plan or account needed on either side.
