## How PDF to JSON conversion works

Effortlessly extract structured data from PDF Document

Mindee’s developer-first API is engineered to seamlessly convert complex PDF architectures—whether they are "born-digital" files with embedded text layers or heavy, image-based scanned PDFs—directly into a clean, structured JSON payload. When a multi-page PDF is submitted via API or SDK, our engine instantly determines the optimal extraction path.

For scanned documents, it rasterizes each page into high-quality images before applying advanced preprocessing and optical character recognition (OCR). The AI then semantically analyzes the entire document context across multiple pages. In milliseconds, it returns a comprehensive JSON response containing precise key-value pairs, page-specific bounding box coordinates, and spatial awareness, making it incredibly simple to integrate complex, multi-page data into your databases, ERPs, and automated workflows.

## Key considerations about PDF to JSON conversion

When converting PDFs to JSON, developers must account for the unique structural challenges of the Portable Document Format. A primary consideration is handling the variability between native vector PDFs and lower-quality rasterized scans, which can impact processing speed and extraction logic. You must also manage multi-page pagination, embedded fonts, complex tables, and file size limitations. While Mindee's robust deep learning models effortlessly parse these mixed-content layouts, ensuring enterprise-grade security remains paramount, as PDFs frequently encapsulate dense financial reports or personally identifiable information (PII).

Mindee guarantees full GDPR and SOC 2 compliance for all API calls. By utilizing the granular, field-level confidence scores embedded in our JSON output, you can seamlessly build smart routing rules to flag ambiguous pages or complex document structures for manual human review.

## FAQ to know more about Mindee's API

### What file formats are supported for JSON conversion ?

The supported document formats are:
- **PDF** (`application/pdf`) – _While technically a document format rather than an image, it is natively supported for all extraction models._  
- **JPEG / JPG** (`image/jpeg`)  
- **PNG** (`image/png`) – _Must be non-animated._  
- **WebP** (`image/webp`)  
- **TIFF / TIF** (`image/tiff`) – _Both single-page and multi-page TIFFs are supported and processed similarly to PDFs._  
- **HEIC** (`image/heic`) – _Apple's High-Efficiency Image Container format._

📌 Important technical limitations to keep in mind:
- **Maximum file size:** 100 MB per file.
- **Maximum page count:** Up to 200 pages per document.
- **File state:** The files cannot be encrypted, and PDFs must not be password-protected.

### Is it possible to batch convert PDFs ?

**Yes, it is absolutely possible to batch process and convert PDFs with Mindee.** The best approach depends on how your "batch" of images or documents is organized.

### Can I try Mindee before subscribing ?

**Yes, you can absolutely try the solution before subscribing.** Mindee offers a **14-day free trial**, and no credit card is required to sign up.
