Pro Tip: Maximizing OCR Accuracy
For optimal OCR results, ensure your scanned documents have high contrast, clear text, and minimal skew. Documents scanned at 300 DPI or higher typically achieve the best recognition accuracy. If processing handwritten content, ensure writing is legible and well-spaced. For multi-language documents, our automatic language detection works best when languages are separated by clear sections rather than mixed within the same paragraph.
Frequently Asked Questions
How accurate is the PDF OCR text recognition?
Our PDF OCR uses Google Document AI technology, achieving 95-99% accuracy on high-quality scanned documents. Accuracy depends on factors like image quality, font clarity, document condition, and language. Printed text typically achieves higher accuracy than handwritten content, while clear, high-resolution scans produce the best results.
What file size limits apply to PDF OCR processing?
File size limits vary by account type: Free users can process PDFs up to 10MB per file. PDF Pro and PRO users can handle files up to 50MB each, perfect for large scanned documents, technical manuals, and multi-page publications. All users get access to the same OCR accuracy and language support.
How many languages does the OCR tool support?
Our OCR tool supports over 100 languages and scripts including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Russian, and many others. The system automatically detects the primary language in your document and applies the appropriate recognition model for optimal accuracy across different writing systems and character sets.
Can the OCR tool process handwritten text?
Yes, our OCR can process handwritten text, though accuracy varies based on handwriting clarity, style, and legibility. Printed text typically achieves 95-99% accuracy, while clear handwriting may reach 80-90% accuracy. For best results with handwritten content, ensure good image quality, sufficient contrast, and legible writing.
How long does OCR processing take?
OCR processing time depends on document complexity and file size: Simple documents (1-5 pages) process in 15-45 seconds. Medium documents (5-20 pages) take 45-120 seconds. Large documents (20+ pages) may take 2-5 minutes. Complex layouts with tables, images, and mixed content require additional processing time.
Does OCR preserve the original document layout and formatting?
Yes, our OCR technology preserves document structure including paragraphs, columns, tables, and basic formatting. The output maintains logical reading order and spatial relationships between text elements. While perfect layout recreation isn't always possible with complex designs, the tool preserves essential document structure for professional use.
Can I OCR password-protected or encrypted PDFs?
OCR processing requires access to the document content, so password-protected PDFs must be unlocked first. If you have the password, you can unlock the PDF and then process it with our OCR tool. The output document can be saved with or without password protection based on your security requirements.
What output formats are available after OCR processing?
Our OCR tool outputs searchable PDF files where the recognized text becomes selectable and copyable while preserving the original document appearance. The text layer is embedded in the PDF, allowing for text search, copy operations, and accessibility features while maintaining the visual integrity of the original document.
Can I process multiple PDF files with batch OCR?
Yes, our tool supports batch OCR processing for multiple PDF files simultaneously. Upload several scanned documents and apply OCR to all files using consistent settings and language detection. This feature is particularly useful for digitizing document archives, converting legacy files, and processing large document collections efficiently.
Is my document data secure during OCR processing?
Absolutely. We prioritize document security with HTTPS encryption for all uploads and processing. Files are processed using Google Document AI in secure cloud environments and automatically deleted after OCR completion. We never store your documents permanently, ensuring complete confidentiality for sensitive business, legal, and personal files.
