Document Uploads

Rekognita supports a wide range of document formats. In this guide, you will learn about supported formats, size limits, and tips for the highest recognition quality.

Supported Formats

Basic Request

curl -X POST https://api.rekognita.com/v1/documents \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@document.pdf" \
  -F "language=en"

Multipage PDFs

Rekognita automatically processes each page of a PDF document. The result contains the text for each page separately:

{
  "id": "doc_abc123",
  "status": "completed",
  "pages": 3,
  "results": [
    { "page": 1, "text": "Page 1...", "confidence": 0.995 },
    { "page": 2, "text": "Page 2...", "confidence": 0.989 },
    { "page": 3, "text": "Page 3...", "confidence": 0.992 }
  ]
}

Tips for Quality

• Resolution — minimum 300 DPI for scans.
• Contrast — text should clearly stand out against the background.
• Orientation — Rekognita automatically detects rotation, but correct orientation improves results.
• No Watermarks — watermarks can reduce accuracy.

Upload Error Handling

If the file does not meet the requirements, the API will return a 400 error:

{
  "error": {
    "code": "invalid_file",
    "message": "Unsupported file format. Accepted: pdf, jpg, png, tiff, webp, bmp."
  }
}
