- Upload the PDF you want to analyse.
- Click Detect Blank Pages — every page is checked for text content and visual content.
- Review the results table showing each page's status (blank or not) and the reason.
Example
A 50-page scanned document is analysed and the tool identifies 3 blank separator pages. The results table shows page numbers, with "Blank — No text, mostly white content" for empty pages and "Not Blank — Contains text content" for pages with data. No file is modified.
Common Use Cases
- Auditing a scanned document before processing to identify empty separator pages.
- Checking whether a PDF has hidden blank pages that waste paper when printing.
- Reviewing a converted document for unexpected blank pages after format conversion.
FAQ
- How does it define "blank"? A page is blank if it has no text content and the rendered image is more than 98% white pixels. Pages with images but no text are reported as "not blank."
