Remove Blank Pages from PDF

Remove pages that meet a blankness threshold

This tool processes uploaded PDF files and removes pages classified as blank by adjustable threshold settings. “Blank” here is an operational detection result, not a universal property of a PDF: the page is judged by image-level blankness parameters. Very pale text, a faint signature, a watermark, or small marks can affect the classification, so the saved file needs a page-by-page review before it replaces the original.

You can upload up to five PDF files in one run; each file is limited to 2.5 MB. The output remains PDF. The controls set a blank threshold and a white-pixel percentage threshold, with defaults of 10 and 95%. These values tune detection; they do not identify a page’s meaning or use OCR to understand its text.

Inspect, adjust, then process

1. Select the PDF files

   Choose one or more PDFs, staying within the five-file and 2.5 MB per-file limits. Keep an unchanged copy if the source is important.

2. Set the detection thresholds

   Adjust the blank threshold and white-percentage threshold if the default behavior does not fit the document. The controls are numeric percentages. Lower or higher settings can change which pages qualify, so test cautiously on documents with faint content.

3. Run the cleanup

   Process the selected files and obtain the resulting PDFs. Detection is heuristic and may not match your own definition of a page worth keeping.

4. Review the output

   Open each result and inspect every removed-page boundary, along with pages containing light marks or pale text. Compare it with the original before sharing or archiving.

Choosing thresholds for scanned documents

A scanner may produce nearly white pages with dust, faint bleed-through, or a light pencil mark. A strict blank-page policy may keep those pages; a more permissive setting may remove a page that contains content you meant to preserve. Start with a copy of the document and inspect the result rather than applying one setting blindly to every file.

Questions before removing pages

Protect content during automated cleanup

• Threshold-based detection can produce false positives and false negatives. A page marked blank may contain light content, and scan noise can make an empty page appear nonblank.
• Always review the processed PDF against the original, especially for signed, annotated, archival, or otherwise important documents.
• Use only files you are authorized to process, and avoid submitting sensitive documents unless the online processing is appropriate for your privacy and handling requirements.
