Claude/Artifact/Q/How much storage comes with Claude artifacts?
How much storage comes with Claude artifacts?
- Short answer: 20 MB of persistent data per artifact, text only. Anthropic does not say whether personal and shared storage split that figure, or give a per-item or per-account total.
- Answer/Official from Anthropic: What are artifacts and how do I use them?.
- The limit is 20 MB per artifact.
- Storage takes text only: no images, files, or binary data. JSON strings fit.
- Personal storage is private to each viewer; shared storage is the same data for everyone using the artifact.
- It is offered on Pro, Max, Team, and Enterprise, on Claude web and Claude Desktop. Free is not listed.
- Legacy artifacts store data only after publishing, and unpublishing deletes it permanently.
- Other documented limits, for artifacts published from Claude Code
- The rendered page must be 16 MiB or smaller, including embedded
data: URIs. Source: Claude Code Docs: Share session output as artifacts. - The
assets capability takes uploads of 20 MiB each (CSS and JS 16 MiB, SVG 2 MiB). This comes from the runtime capability notes in the Claude Code session, not from a public doc.
- Uploaded images and other files
- People who can edit an artifact can upload images, PDFs, and CSVs to it. Claude Academy says each artifact has a storage limit and sends readers to the Help Center for the amount; the help article gives only the 20 MB text-only figure, so whether uploads share that pool is unstated.
- On Team and Enterprise, uploaded assets are stored persistently under the organization's data retention and deletion policies. Artifacts admin guide lists no storage quota, per-file limit, or organization-wide cap, and shows no page for storage figures.
- Artifact activity counts toward each user's usage limits, shared with the rest of Claude including Claude Code; there is no separate allowance. That covers usage, not stored bytes.
- The 1 TB per-organization storage figure belongs to the developer Files API, not artifacts.
- Unverified: I found no published cap on the number of documents, on total
db capability size, or on organization-wide artifact storage. See Claude/Artifact/Q/How can I find my storage quota for Claude artifacts on seat-based Enterprise?.
