What ChatGPT Can Do with Image Text
When you share an image with ChatGPT (requires ChatGPT Plus or the API with a vision-capable model), it can describe text in the image, summarise a document, or answer questions about the content. It can also transcribe simple, short passages reasonably well in many cases.
Why ChatGPT Is Not Reliable for Verbatim OCR
ChatGPT is a language model, not an OCR engine. Key limitations:
- Paraphrasing: It may rephrase sentences rather than transcribe them exactly
- Hallucination: It can invent characters or words not in the image
- Layout loss: Tables, columns, and formatting are typically not preserved
- Long documents: Multi-page PDFs or dense text may be truncated or summarised
- Cost: Requires ChatGPT Plus ($20/mo) for vision features
When to Use jpg.now Instead
Use jpg.now's Image to Text when you need:
- Verbatim transcription of a document, contract, or invoice
- Preserved table structure and column alignment
- Bulk text extraction from multiple images or PDF pages
- A free tool with no account or subscription required
jpg.now uses a dedicated OCR engine that returns the exact characters present in the image, including special characters, numbers, and punctuation, without any creative interpretation.
When ChatGPT Is the Right Tool
ChatGPT vision is a good choice when you want to understand image content rather than copy it - For example, asking "what does this chart show?" or "summarise this screenshot of a report". It also handles mixed image/text analysis well, like extracting insights from a photo that contains both visual data and text labels.
