This tool processes scanned PDF files. Many PDFs consist of images rather than text. Computers cannot search inside images. This software uses OCR, or Optical Character Recognition, to read those images. It converts the visual data into searchable text. You can process thousands of files in one batch. Once the process finishes, you search your documents for specific keywords.
Ensure your computer meets these standards before you begin:
- Windows 10 or Windows 11.
- At least 8GB of RAM. Processing large batches requires memory.
- 500MB of free disk space for the program installation.
- A stable processor. Multi-core processors speed up the OCR process significantly.
Follow these steps to set up the tool on your machine:
- Visit the releases page.
- Look for the latest version at the top of the list.
- Click the link that ends in .exe to download the installer.
- Locate the downloaded file in your Downloads folder.
- Double-click the file to start the installation.
- Follow the on-screen prompts.
- Click Finish to launch the application.
The main interface allows you to manage your documents. Follow this process to scan your first folder:
- Open the application from your Start menu shortcut.
- Click the Button labeled Select Folder.
- Choose the directory on your computer containing the scanned PDF files.
- Select your language settings if the documents contain non-English characters.
- Click the Run OCR button.
- Wait for the progress bar to reach completion.
- The application creates a hidden index file for your documents.
After the initial scan, you search your documents through the search bar:
- Type your desired keyword into the search field.
- Press Enter or click the Search button.
- The tool generates a list of files containing the keyword.
- Click any file in the list to open it.
- The application highlights the instances where the text appears.
You adjust the performance of the tool in the Settings menu:
- OCR Quality: Choose between speed and accuracy. High accuracy takes more time but reads handwriting better.
- Output Location: Choose where your index files go. Keeping them on a fast drive improves performance.
- File Filtering: Choose to ignore specific file types if you only want to process PDF files.
If you face problems, review these solutions:
- Software does not start: Check if you have the latest drivers for your graphics card or Windows updates.
- OCR takes too long: Reduce the number of files in your folder. Process large batches in smaller groups.
- Search returns no results: Ensure the OCR process finished for those specific files. Check that you spelled your search term correctly.
- Application freezes: The computer may run low on memory. Close background applications to free up resources.
- Missing text in search: High-resolution images provide better results. Ensure your scans are at least 300 DPI.
This software performs all tasks locally on your computer. It does not send your documents or data to a server. Everything stays on your hard drive. Your information remains private throughout the process.
The quality of your search depends on the quality of your source files. Follow these tips to get the best results:
- Use clear, high-contrast scans.
- Straighten tilted pages before scanning if possible.
- Remove staples or paperclips that create shadows on the page.
- Group files by document type.
- Avoid scanning very faint pencil marks.
