Clean up double-sided ADF scans in seconds. One-click blank page detection ignores scanner border shadows and dust specks, highlights empty pages for review, and strips deleted page data—locally in your browser.
Opens your PDF and immediately scans every page for text layers, stamps, and handwriting—marking blank backsides so you can delete them all at once.

Click thumbnails to toggle deletion and download clean PDFOffice sheet-fed scanners almost never produce pure white #FFFFFF images on empty backsides—paper tint, punch holes, and feeder shadow bands fool naive tools into keeping blank pages, while aggressive thresholds wipe out pages with a single signature or page number.
| Document Quirk | Basic Threshold Tools | NeatCompress Connected-Component Engine |
|---|---|---|
| Off-white / gray scan background | Treats gray paper tint as content (misses blank page) | Estimates median paper luminance & chroma per page |
| Black feeder shadow line on page edge | Counts dark border pixels as text | Excludes monochrome border bands confined to the outer 5% margin |
| Tiny scanner dust specks | False negative on dusty glass | Ignores isolated micro-specks below the DPI-scaled ink cluster threshold |
| Colored stamp, signature, or selectable text | Risk of silent deletion if overall page ink < 1% | Always kept—checks PDF text layer + chroma ink clusters + mandatory visual review |
