Key Features

Auto-Detect Blank Pages

The tool renders each page and measures ink coverage to find truly empty pages, then marks them on the preview.

Adjustable Sensitivity

Choose strict, normal, or loose detection. Loose catches pages with only faint marks or a small logo; strict keeps only fully empty pages.

Manual Override

The detected blank pages are pre-filled as an editable list. Add or remove pages before running, so you stay in control.

Visual Confirmation

Page thumbnails show an amber Blank badge on detected empty pages, so you can verify before removing anything.

Private & Local

Detection and removal run entirely in your browser with pdf-lib. Your PDF is never uploaded to a server.

How to Use

1

Add a PDF

Drag and drop or select the PDF you want to clean up. The file is read locally in your browser.

2

Review Detected Blanks

The tool scans pages and marks blank ones with an amber badge; the summary shows how many pages will be removed and how many remain.

3

Adjust If Needed

Change the detection sensitivity or edit the page list to add or remove pages from the removal plan.

4

Remove and Download

Run the tool to create a new PDF without the blank pages, then review the result and download it.

Remove Blank PDF Pages Example

A 12-page scan has 2 blank pages inserted by the printer; they are detected and removed, leaving a 10-page PDF.

PDF
scan.pdf (12 pages)

A scanned document with accidental blank pages.

PDF
scan-no-blanks.pdf (10 pages)

Blank pages are removed and the rest stay in order.

How to Remove Blank Pages from a PDF

Why Remove Blank Pages

Blank pages sneak into PDFs from extra page breaks, scanner misfeeds, exported slides, or printer defaults. This tool finds those empty pages and removes them so you can share or print a cleaner document.

Quick Answer

Upload a PDF, let the tool detect blank pages, review the marked thumbnails, then download a new PDF with the empty pages gone. Everything runs locally in your browser.

How Blank-Page Detection Works

The tool renders each page and measures ink coverage. Pages with almost no visible content are flagged as blank. Because detection is heuristic, the preview marks each suspected blank page with an amber badge so you can confirm before removing anything.

Choose a Detection Sensitivity

Strict keeps only fully empty pages. Normal is the recommended balance for everyday scans. Loose also catches pages that contain only a faint mark, a small logo, or a page number — useful when blank pages still carry a footer or watermark.

Review and Override

The detected blank pages are pre-filled into an editable list. Add pages the tool missed, or remove a page that was flagged by mistake. You stay in control of exactly what gets deleted.

Remove Blank Pages on a Mac

On a Mac you can open a PDF in Preview, show the thumbnail sidebar, and delete empty pages by hand. An online blank-page remover gives you the same result in a browser and adds automatic detection so you don't have to scan every thumbnail yourself.

Remove Blank Pages Versus Delete Pages

This tool automatically finds and pre-fills blank pages. If you want to remove specific pages by number instead, use Delete Pages from PDF, where you enter the exact pages or ranges to remove.

Remove Blank Pages Versus Split PDF

Removing blank pages produces one shorter PDF. Splitting a PDF produces multiple separate files by page range. When your goal is a single clean document, blank-page removal is the right choice; use Split PDF when you need separate files.

After Removal

The remaining pages keep their original order and size. If you later need to combine several cleaned files, Merge PDF puts them back into one document.

Frequently Asked Questions

How does the tool find blank pages?

It renders each page in your browser and measures how much ink is on it. Pages with almost no visible content are flagged as blank. Detection is heuristic, so always review the marked pages before removing them.

Can I choose how sensitive the detection is?

Yes. Strict only flags fully empty pages. Normal is the recommended default. Loose also catches pages that contain only a faint mark, a small logo, or a page number.

What if a page with content is wrongly flagged?

Detection is based on ink coverage, so a near-empty page with just a footer or watermark can be flagged. You can remove it from the list before running, or switch to strict sensitivity.

Can I remove pages the tool did not detect?

Yes. The detected blank pages are pre-filled into an editable list. Add any extra page numbers you want removed, or clear the list to remove nothing.

Will the original PDF be changed?

No. A new PDF is created without the blank pages. Keep the original file if you may need to restore the deleted pages later.

Are my PDF files uploaded?

No. Detection and removal run locally in your browser. Your PDF is never sent to a server.
