# Workspaces File Types and Limits

> Check Workspaces document, artifact, quota, MCP, live-connection, gallery, and version limits.

Workspaces stores Markdown and HTML as documents. Other supported files are
[artifacts](/workspaces/documents/artifacts). Artifact quota counts every
retained version, not only the current file.

## Document limits

| Limit            | Value                             |
| ---------------- | --------------------------------- |
| Document types   | Markdown and HTML                 |
| Document body    | 1,572,864 UTF-8 bytes, or 1.5 MiB |
| Live connections | 50 per document                   |

The New document dialog treats `.html` and `.htm` as HTML. It treats every
other suffix as Markdown, so use `.md` or `.markdown` for Markdown files.

## Artifact types and limits

| Limit                                      | Value                                                                                                                                        |
| ------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------- |
| Supported types                            | PNG, JPEG, GIF, WebP, SVG, PDF, MP4, WebM, JSON, CSV, plain text, CSS, ZIP, and JavaScript when the browser reports `application/javascript` |
| One artifact file                          | 104,857,600 bytes, or 100 MiB                                                                                                                |
| Personal or Free retained artifact history | 1,073,741,824 bytes, or 1 GiB, per workspace                                                                                                 |
| Organization retained artifact history     | 107,374,182,400 bytes, or 100 GiB, across all organization workspaces                                                                        |
| Artifact wall                              | Newest 200 items                                                                                                                             |

Document bytes do not count toward artifact quota. Artifact history does.
Deleting the current artifact path does not remove its retained versions from
quota accounting. Deleting the workspace removes those versions from quota
accounting, but stored bytes may remain until cleanup.

## MCP limits

| Limit                                                 | Value             |
| ----------------------------------------------------- | ----------------- |
| `workspaces.publish_artifact` inline decoded body     | 20 MiB            |
| Raw HTTP artifact upload                              | 100 MiB           |
| `workspaces.get_artifact(include_content: true)` text | 50,000 characters |

Use raw HTTP for an artifact larger than the MCP inline limit. Binary MCP reads
return URLs instead of putting the bytes in the tool result.
