The concrete limits Regnora enforces. Refer here when sizing an upload or working out why something was rejected.

## Documents and uploads

| Limit | Value |
| --- | --- |
| Maximum size per file | **50 MB** |
| Supported file types | PDF, Word (`.docx`, `.dotx`, `.rtf`), PowerPoint (`.pptx`, `.potx`), Excel (`.xlsx`, `.xltx`, `.xls`), `.csv`, HTML, `.txt`, `.md` |
| Archives | ZIP and RAR are extracted on upload, up to **500 MB** uncompressed |
| Concurrent uploads | Up to **10** files upload at once; the rest queue |

Very large Office files are still imported — if one exceeds the limit of Regnora's primary text extractor, it falls back to a simpler extraction rather than failing.

## Field lengths

| Field | Maximum |
| --- | --- |
| Agent name, skill name | 200 characters |
| Agent description, skill description | 500 characters |
| Assessment comment | 2,000 characters |
| Person, organisation, and project names | 255 characters |

## Plans and credits

Regnora's usage runs on **credits** and **contributor seats** rather than fixed per-plan caps on projects, documents, or agents. Contributors are the members who can run gap analyses and spend credits; you can see how many contributor seats are in use on the [Members](/guides/members-roles-and-permissions/#contributor-seats) page. For what's included in your plan and how billing works, see [Pricing and billing](/resources/pricing-and-billing/).
