title: Limitations | Developer Documentation
description: Current limitations for LlamaParse services including file size limits, page limits, processing timeouts, schema constraints, and concurrency limits.
---

This page documents the current service limitations across LlamaParse products. See also [Rate Limits](/llamaparse/general/rate_limits/index.md) for API rate limiting details.

## General

These limits apply across all LlamaParse services:

| Limit             | Value | Notes                                                                    |
| ----------------- | ----- | ------------------------------------------------------------------------ |
| Maximum file size | 512MB | Platform-wide upload limit; individual services may enforce lower limits |

## Parse

| Limit                             | Value        | Notes                                                                                 |
| --------------------------------- | ------------ | ------------------------------------------------------------------------------------- |
| Supported file formats            | 130+ formats | See [Supported Document Types](/llamaparse/general/supported_document_types/index.md) |
| Maximum images extracted per page | 35           | Only the 35 largest images are extracted/OCR processed                                |
| Maximum text extracted per page   | 64KB         | Content beyond 64KB is ignored                                                        |

### Timeout Behavior

Parse jobs have a configurable timeout composed of:

- **Base timeout**: up to 2 hours (7,200 seconds)
- **Per-page timeout**: up to 5 minutes (300 seconds) additional time per page

The total timeout is calculated as: `base timeout + (per-page timeout × page count)`.

## Extract

| Limit                         | Value              | Notes                                                             |
| ----------------------------- | ------------------ | ----------------------------------------------------------------- |
| Maximum file size             | 100MB              |                                                                   |
| Maximum pages per extraction  | 500                | Enforced for files larger than 5MB                                |
| Maximum schema properties     | 5,000              | Total properties across the entire schema                         |
| Maximum schema nesting depth  | 7 levels           |                                                                   |
| Maximum schema string content | 120,000 characters | Combined total for all field names, descriptions, and enum values |
| Maximum raw JSON schema size  | 150,000 characters |                                                                   |

For workflows that exceed these limits, we recommend splitting the job into smaller, targeted extraction jobs. See the [Split and Extract](/llamaparse/extract/examples/split_and_extract_resume_book/index.md) example for a walkthrough. For more details on schema constraints, see [Schema Design and Restrictions](/llamaparse/extract/guides/schema_design/index.md).
