Make Scanned PDFs Searchable
Unlock the hidden text within your scanned documents without ever uploading them to the cloud. PlatinumPDF OCR uses high-performance neural recognition to add an invisible, searchable text layer to your static images and PDFs. This enables keyword searching (Ctrl+F) and precise text selection in any standard PDF viewer, preserving your original layout while adding full digital utility. Local processing ensures your most sensitive discovery documents remain strictly on your device.

Real-World Scenarios
Scenario 1: The E-Discovery Audit
Input: A folder containing 100 scanned PDFs of old meeting minutes.
Action: User runs 'Multilingual OCR' in English.
Output: A set of PDFs where they can search for the term 'Budget 2022' and jump straight to every mention across all files.
Scenario 2: The Data Entry Shortcut
Input: A 5-page scanned invoice from a vendor.
Action: User processes with OCR and uses the 'Preview' mode.
Output: The user highlights and copies the table data directly from the image into their Excel spreadsheet.
Scenario 3: The Thesis Quote
Input: A photo of an old physical book page from a library.
Action: User uploads the image to the OCR tool.
Output: A searchable PDF is created, allowing the student to copy a 200-word quote perfectly without retyping a single character.
Frequently Asked Questions
How accurate is the OCR process?
For high-quality typed documents, our engine (powered by advanced LSTM neural networks) typically reaches 98-99% accuracy. For low-resolution scans, unusual fonts, or documents with heavy noise, accuracy may drop, but the text remains highly searchable.
What languages are supported?
We support over 100 languages, including English, Spanish, French, German, Italian, Chinese (Simplified/Traditional), Japanese, and many more. Selecting the correct language significantly improves recognition accuracy.
Is it safe to OCR sensitive documents like medical records?
Yes. PlatinumPDF uses 100% client-side OCR. The Tesseract.js engine runs directly in your browser. Unlike other online converters, your documents are never uploaded, stored, or seen by our servers.
Can I extract text from handwritten notes?
Our current technology is optimized for printed and typed text. While it can often recognize very neat handwriting, it is not primarily designed for complex script or cursive and may produce errors.
Does it work with multi-column layouts like newspapers?
Yes. Our engine performs automatic layout analysis, attempting to detect and reconstruct the logical reading order of columns and text blocks.
How long does it take?
Processing speed depends on your device's CPU. A typical page takes between 1-5 seconds to fully recognize and index.
