OCR & PDF Tools FAQ¶
Frequently asked questions about OCR & PDF Tools.
General¶
What is OCR & PDF Tools?¶
OCR & PDF Tools is a Windows desktop application that extracts text from images and PDFs using optical character recognition (OCR). It also includes a full suite of PDF management tools including merge, split, convert, and password protection.
Does it require an internet connection?¶
No. After installation and license activation, OCR & PDF Tools works 100% offline. All text recognition is performed locally on your computer using the Tesseract OCR engine. Your documents never leave your machine.
What operating systems are supported?¶
Windows 10 and later (64-bit). macOS and Linux are not currently supported.
Is there a free trial?¶
Yes. Download the trial from the OCR & PDF Tools product page to explore the features before purchasing.
OCR Questions¶
How many languages are supported?¶
Over 100 languages are supported. See Supported Languages for the full list.
What OCR engine is used?¶
OCR & PDF Tools uses Tesseract, one of the most accurate open-source OCR engines available. All processing runs locally on your machine.
Can I OCR a scanned PDF?¶
Yes. The application can process individual pages of a scanned PDF by converting them to images and running OCR on each page.
How can I improve OCR accuracy?¶
- Use high-quality images (300 DPI or higher)
- Select the correct language before running OCR
- Use Advanced OCR preprocessing for difficult images
- Ensure images are straight and well-lit
Can I OCR multiple images at once?¶
Yes. Use batch processing to run OCR on multiple image files sequentially. Results are saved to individual text files.
PDF Questions¶
Can I merge PDFs with different page sizes?¶
Yes. The merge feature combines PDFs regardless of page size. Each page retains its original dimensions in the merged output.
What encryption does the password feature use?¶
PDF password protection uses standard PDF encryption as defined in the PDF specification. This provides industry-standard security for document protection.
Can I convert a scanned PDF to a searchable PDF?¶
Yes. Run OCR on the scanned PDF, then save the result as a new PDF with the text layer embedded. This creates a searchable PDF.
What is the maximum file size I can process?¶
There is no hard limit, but very large files (hundreds of MB) will require more time and memory. For best performance, split large PDFs into smaller segments before processing.
Privacy and Security¶
Is my data sent to any server?¶
No. OCR & PDF Tools processes everything locally. No data is sent to external servers. This makes it safe for confidential, medical, legal, and government documents.
Where are my files stored?¶
All output files are saved to the location you choose. The application does not upload, cache, or transmit your files anywhere.
Licensing¶
How many devices can I use?¶
Each license key supports activation on a limited number of devices. Deactivate on one machine before activating on another.
Can I use it for commercial purposes?¶
Yes. The extracted text and converted documents can be used for any purpose, including commercial projects.
