Google Cloud Vision OCR vs AWS Textract for scanned PDFs

For scanned PDFs, AWS Textract is usually the better choice if your main goal is extracting structured text from documents. Google Cloud Vision OCR is strong at general OCR, but Textract is designed more specifically for document understanding.

Quick take

• Choose AWS Textract if you need:
  • text + layout preservation
  • tables
  • forms / key-value pairs
  • document-centric extraction from scanned PDFs
• Choose Google Cloud Vision OCR if you need:
  • straightforward OCR
  • broad language support
  • good performance on mixed image/document inputs
  • simpler OCR-only use cases

Key differences for scanned PDFs

1) OCR quality

Both are good at printed text in clean scans.

• Textract tends to do better when the PDF is a business document, invoice, form, or structured report.
• Vision OCR is often excellent at raw text recognition and can be very strong on multilingual content.

2) Layout and structure

This is where Textract usually wins for scanned PDFs.

• Textract:
  • detects pages, lines, words
  • extracts tables
  • identifies forms and key-value relationships
  • returns richer document structure
• Vision OCR:
  • gives OCR text and positioning
  • less document-structure oriented
  • better if you plan to build your own layout parsing

3) Tables and forms

• Textract is generally much better for tables/forms.
• Vision OCR can read text in tables, but table reconstruction is up to you.

4) PDF handling

Both support PDFs, but:

• Textract is commonly used for multi-page scanned PDFs in document pipelines.
• Vision OCR works well too, especially via batch/document OCR, but is less specialized for downstream extraction.

5) Ease of use

• If you want just OCR text, Vision is straightforward.
• If you want usable business document output, Textract is more convenient.

When to prefer each

Prefer AWS Textract if:

• invoices, receipts, contracts, forms, claims, statements
• scanned PDFs with tables
• you need key-value extraction
• you want less post-processing

Prefer Google Cloud Vision OCR if:

• you need general-purpose OCR
• document structure is not important
• you want strong multilingual recognition
• you’ll handle layout parsing yourself

Cost and scaling

Pricing changes often, but in practice:

• Textract can become more expensive if you use tables/forms features.
• Vision OCR may be cheaper for pure OCR use cases. Check current pricing for your region and document volume.

Recommendation

If your input is specifically scanned PDFs and you care about extracting structured information, start with AWS Textract.
If your goal is just accurate OCR text extraction, especially across varied languages and image types, start with Google Cloud Vision OCR.
