This is NOT an OCR tool. It is a specialized sub-tool that cleans images to significantly improve the accuracy of any OCR software you use later.
No, this tool handles the **pre-OCR stage.** Use it to clean up poorly scanned documents (enhance contrast, remove noise) before feeding them into an OCR engine for better results.
Even expensive OCR software makes mistakes with low-quality images. This sub-tool quickly prepares images to be **OCR-ready**, saving you hours of manual editing and error correction later.
- **Binarization**: Strips the background to highlight text in pure black.
- **Grayscale**: Removes color noise for cleaner scanning.
- **Contrast Adjustment**: Makes faint text sharp and readable.
**Absolutely.** Like all Max-PDF tools, this processes everything **locally in your browser.** No files are sent to a server, ensuring 100% privacy for your sensitive documents.
Save the optimized images as a PDF. Then, upload it to Google Drive OCR or any professional software. You’ll notice a significant drop in errors compared to the original file.
It improves image quality, but it can't reconstruct text that is physically gone. It's most effective for **dark, low-contrast, or colorful scans** that confuse standard OCR engines.
