Delete Blank Pages from a PDF

Scanners often add an empty page between sections or at the end of a batch. This tool checks every page, finds the ones that came out blank, and removes them.

Files are never uploaded

How to use it

Add the scanned PDF

Drop the file above. The tool looks at every page, so a longer document takes a little more time.

Choose how strict to be

Balanced suits most scans. Choose Conservative if you are worried about losing a page that has only a small amount of content, or Aggressive if your scanner leaves faint marks that stop nearly-empty pages being detected.

Let it check the pages

Each page is rendered as a small thumbnail and examined for marks. The progress bar shows which page is being checked.

Review the outcome

If no blank pages are found you are told so and nothing is removed. Otherwise the blank pages are dropped and the rest are kept in order.

Download and spot-check

Download the cleaned file and compare the page count with the original. Keeping the original scan means you can always run it again with a different sensitivity.

Common issues

Faint marks defeat the detector

A grey shadow down the edge of a page counts as content. Crop the scan first, or switch to the Aggressive setting, and check the result carefully.

Aggressive can remove a nearly-empty page

A page holding only a page number or a single line can fall below the threshold on the Aggressive setting. Use it only when you are willing to check the output page by page.

Detection is not instant

Every page has to be rendered, so a long scan takes time in proportion to its length. The progress bar is your signal that it is still working.

Removed pages are not in the result

The saved file no longer contains them. Keep your original scan if you might need those pages later.

Frequently asked questions

How does it decide a page is blank?

It renders each page at low resolution and measures how much of the page is covered by marks. A page with almost nothing on it is treated as blank.

Will it delete a page that has a small amount of text?

It should not on the Balanced setting: even a short paragraph produces far more marks than the threshold. On the Aggressive setting a page with only a faint mark can be removed, so check the result before deleting your original.

Why did it miss a blank page from my scan?

Scanners often add grey noise, a shadow down one edge, or a black scan line, and those count as marks. Try the Aggressive setting, or crop the stray edge first with Crop PDF and run it again.

Does it change the pages that are kept?

No. The pages you keep are copied exactly as they are; only the blank ones are left out.

What if every page is blank?

The tool refuses to save a document with no pages at all. Check that you selected the right file, or that the scan really did capture content.

Can I remove specific pages instead?

Yes — if you already know which pages are unwanted, use Extract PDF Pages or Rotate & Delete PDF Pages, which take an explicit list of page numbers.

Will the file get smaller?

Somewhat. Removing pages drops their content, though objects shared with other pages may still be referenced. Run Compress PDF afterwards for a bigger reduction.

Is my scan uploaded?

No. The pages are rendered and re-assembled in your browser. Nothing is sent to a server.

Does it work on text PDFs, not just scans?

Yes, though an ordinary text document rarely contains truly blank pages. It is most useful for scans and photographed batches.
