About this tool

Remove Blank Pages scans every page of your PDF for both selectable text and rendered pixels, and marks any page as “blank” when it has neither. You review the detected pages, then apply the deletion in one click. The output is a lossless PDF with just the meaningful pages.

All processing is 100% client-side. Your PDF is opened inside your browser tab, edited with pdf-lib (and rendered with pdf.js when needed), and saved as a Blob download. Nothing is ever uploaded to any server and closing the tab wipes every working buffer.

Why choose this tool

Auto-detect

Text + pixel luminance heuristics identify blanks.

Local only

Detection and removal happen in your browser.

Adjustable

Slide the threshold for stricter or looser detection.

Confirmation step

You review the flagged pages before anything is removed.

How it works

1
Upload the PDF (usually from a scanner).
2
Press Detect — the tool flags blank pages.
3
Verify the highlighted pages, then press Remove.
4
Download the cleaned PDF.

Popular use cases

Clean up scanner output that inserted blank pages between originals

Remove empty pages after a duplex scan of a single-sided document

Trim placeholder pages from a template-based report

Tips & best practices

Preview the detected blanks before applying — sometimes a very light watermark counts as blank
For a manual review workflow, use Delete PDF Pages with the visual thumbnail grid
Combine with Reorder PDF Pages afterwards to tidy up the remaining sequence

How the detector works

For each page, the tool asks pdf.js for the text content. If the text is empty (or contains only whitespace), the page is flagged as “likely blank”. As a second check, it renders the page onto a small canvas and computes the average luminance. If the page is overwhelmingly white (above a configurable threshold), the flag is confirmed. Only pages that pass both checks are marked for removal, so pages with faint content are safe by default.

Sensitivity

The sensitivity slider controls the luminance threshold. Conservative sensitivity flags only clearly-empty pages (safe default). Aggressive sensitivity also flags very lightly-marked pages such as scanner artefacts and faint stamps. Always review the highlighted pages before pressing Apply — the tool never removes pages until you confirm.

When to use this vs. Delete PDF Pages

For manual, thumbnail-based cleanup use Delete PDF Pages. For automated bulk cleanup where you trust the detector, use this tool — you’ll save clicks on large scanned batches. Both tools produce lossless outputs and preserve fonts / vectors on the kept pages.

Privacy note

Your files never leave your browser. All parsing, page rendering and PDF assembly happens locally on your device using open-source libraries (pdf-lib and pdf.js). ilovedigital.in cannot see, store or share the contents of your documents.
