Image OCR Parse

What It Does

Extracts text from images via the PDFAPIHub hosted OCR API. Your image is uploaded to PDFAPIHub servers where Tesseract OCR processes it and returns the extracted text. Supports optional image preprocessing to improve OCR quality on low-resolution or noisy inputs.

When to Use

• Extract text from photos of receipts, signs, or documents
• OCR business cards, ID cards, or labels
• Process low-quality images with preprocessing

Required Inputs

Provide one of:

• image_url — URL to an image
• base64_image — base64-encoded image
• Multipart upload with file field
