What types of scanning artifacts can PDF Scan Cleaner remove?

PDF Scan Cleaner can remove various scanning artifacts including speckles, grain, dust particles, scanner noise, and compression artifacts. It uses advanced median filtering algorithms to smooth out unwanted noise while preserving important document details like text and line art.

Does the tool work on all types of scanned documents?

Yes, PDF Scan Cleaner works effectively on most scanned documents including text documents, forms, photographs, blueprints, and mixed-content pages. It's particularly effective for documents scanned at 300 DPI or higher, but can also improve lower-quality scans.

Will the cleaning process affect the text readability?

No, the cleaning process is designed to enhance text readability rather than degrade it. The sharpening filters specifically improve text clarity while noise reduction removes background artifacts. However, we recommend using moderate settings (20-40% sharpening) to avoid over-processing.

Is my document data secure during processing?

Absolutely. All processing happens locally in your browser using JavaScript and Canvas API. Your document never leaves your device, ensuring complete privacy and security. No data is uploaded to external servers or stored anywhere.

What file size limits should I consider?

PDF Scan Cleaner supports files up to 100MB. For larger documents, we recommend processing them in smaller sections or using a more powerful device with sufficient RAM. Processing time will vary based on document size and complexity.

Can I undo or modify the cleaning after processing?

Once processed, the cleaning effects are permanent in the downloaded PDF. However, you can process the original file multiple times with different settings to achieve your desired result. We recommend keeping a copy of your original document.
