How CleanPDFPages Works

Drop your PDF files into the tool or browse your device. Batch support allows processing multiple multi-page documents (up to 500 MB total) in a single session. Your files remain on your local storage.

• Supported formats: Digital PDFs, scanned documents, image-only PDFs
• No account creation, login, or subscriptions needed
• Immediate asynchronous client-side parsing

CleanPDFPages analyzes each page locally using a combination of text token extraction, margin-masked luminance variance (to find blank pages), and 128-bit perceptual difference hashing (to spot duplicates).

• Blank detection ignores scanner borders and punch holes
• Perceptual dHash detects scanned copies across documents
• Separates true duplicates from recurring template forms

Every flagged page is marked with a clear suggestion badge ('Possible Blank' or 'Possible Duplicate'). Open the high-resolution review board to compare duplicate candidates side-by-side and toggle removals.

• Full high-res rendering with zoom and keyboard navigation
• Side-by-side reference comparison with original duplicate source
• Non-destructive workflow: you decide which pages to keep or remove

Click Clean & Download to generate a freshly sanitized PDF with all unwanted pages removed. Your original files remain completely untouched on your device.

• Preserves original vector fonts, bookmarks, and image quality
• Generates separate downloads for each processed document in batch
• Zero network latency: downloaded directly from browser memory
