Perplexity file upload limits in 2026: 25 MB files, 50 files per project, formats, and Enterprise repositories
Updated: 2 days ago
Perplexity supports file analysis across Search, Projects, and enterprise knowledge workflows, but file size, file count, retention, and repository limits are separate constraints.
Current Perplexity guidance lists a 25 MB maximum per uploaded file in Spaces workflows, while Pro supports up to 50 file uploads per project. Enterprise plans can scale far beyond that through indexed repositories and connectors.

FILE SIZE AND FILE COUNT ARE DIFFERENT LIMITS
A project may allow many files while still enforcing a per-file size ceiling. The current official Spaces guidance lists 25 MB per file, while Pro plan documentation separately advertises up to 50 uploaded files per project.
........
Constraint | Current guidance | Practical effect |
|---|---|---|
Single uploaded file | 25 MB in current Spaces guidance | Large PDFs may need splitting or connector-based ingestion |
Pro project | Up to 50 file uploads | Suitable for bounded research projects |
Enterprise Pro indexed project | Up to 500 files | Larger curated knowledge bases |
Enterprise Max indexed project | Up to 5,000 files | Large-scale project knowledge |
Enterprise Max personal repository | Up to 10,000 files in current plan docs | Persistent personal knowledge store |

PERPLEXITY CAN ANALYZE MORE THAN PDFS
Perplexity's Pro documentation describes uploads including PDFs, CSV files, audio, video, images, and other supported document types. File analysis is intended to add private context to a query rather than replace the web-search layer.
··········
PROJECTS ARE FOR PERSISTENT RESEARCH CONTEXT
Projects let users group threads and files around a topic. For Pro users, the current plan guide lists up to 50 file uploads per project, making Projects more suitable for ongoing work than repeatedly attaching the same documents to isolated searches.
··········
ENTERPRISE CONNECTORS SCALE BEYOND MANUAL UPLOADS
Enterprise deployments can index selected files and folders from sources such as Google Drive, SharePoint, and OneDrive. Current connector documentation lists up to 500 indexed files per project for Enterprise Pro and 5,000 for Enterprise Max, with larger per-user totals.
··········
RETENTION DEPENDS ON THE WORKFLOW
Perplexity's official Spaces guidance states that uploaded files are retained for 30 days for follow-up queries, while incognito mode is designed for zero-retention sessions. Indexed enterprise connectors use a different persistent storage model tied to the organization and source synchronization.
··········
LARGE DOCUMENTS MAY NEED A DIFFERENT INGESTION STRATEGY
A 25 MB upload ceiling can become the limiting factor before model context. Large archives are better handled through project-level organization, enterprise indexing, or selective extraction rather than repeatedly attaching a monolithic document.
··········
FILE LIMITS ALSO DEPEND ON PLAN-SPECIFIC RATE LIMITS
Perplexity separates persistent repository capacity from upload-session allowances. Free has limited uploads, Pro and Max use larger weekly allowances, and Enterprise tiers expose higher organizational limits. File-count capacity therefore should not be confused with how many new upload sessions can be started in a given week.
