How to remove blank pages from a scanned PDF

The quickest way to remove blank pages from PDF scans is to look at every page as a thumbnail, select the empty ones together and delete them in one go. Our free Organize PDF Pages does this inside your browser: open the scan, tick the blank pages, press Delete and download the cleaned file. It does not detect blank pages automatically, so you pick them by eye, but with the shortcuts below that usually takes less than a minute.

Why scanned PDFs end up with blank pages

Blank pages in a scan almost always come from the scanner settings, not from the paper:

• Double-sided scanning of single-sided paper. If the scanner is set to scan both sides, every back of a one-sided page becomes an extra, empty page. A 10-page letter turns into a 20-page PDF with every second page blank.
• Cover sheets and separators. The back of a cover, a coloured separator sheet or an empty form page gets scanned like everything else.
• Phone scanning. A scanning app may capture an empty sheet if you tap the shutter twice or the page under the camera is turned over.

"Blank" is also rarely pure white. A scanned empty page is often light grey, has a few dust specks, or shows faint mirrored text from the other side of thin paper. That is why it is worth a quick look before deleting.

How to remove blank pages from PDF scans, step by step

1. Open the scan. Go to Organize PDF Pages and choose your PDF, or drop it onto the page. You can open up to 20 PDFs, about 200 MB in total.
2. Make the previews smaller. Use the size slider (or the small grid button) in the toolbar so you can see many pages on one screen. Blank pages stand out as plain rectangles.
3. Select the empty pages. Click a page or tick its circle to select it. Shift-click selects a whole range. On a computer you can also drag a box over several pages on the empty space around them.
4. Use Even pages for double-sided scans. If every second page is blank, open Select and choose Even pages. Then click any even page that does have content to remove it from the selection.
5. Check doubtful pages. Double-click a page, or choose Preview in its ⋯ menu, to see it large. Use Previous and Next to step through.
6. Delete. Press Delete in the bar at the top, or the Delete key. The page count updates straight away.
7. Download. Click Download PDF. The new file is named after the original with -organized added, and the tool shows the page count before and after.

Made a mistake? Undo (Ctrl+Z) brings deleted pages back, and Redo (Ctrl+Y) repeats the step.

Does the tool find blank pages automatically?

No. Organize PDF Pages has no automatic blank-page detection. The Blank pages entry in the Select menu only picks blank pages that you inserted in the tool yourself, not empty pages that were already in your scan.

Picking pages by eye has one real advantage: you decide. A page that looks almost empty may hold a signature, a stamp, a page number or a faint pencil note, and on official papers such as land documents or certificates that small mark can matter. With the thumbnails and Preview you see exactly what you are deleting.

How to spot blank pages quickly

What the thumbnail shows	What it usually is	What to do
Plain white or light grey	A truly empty page	Select and delete
Faint mirrored text	Bleed-through from the other side of thin paper	Preview it, then delete
A few specks or a dark line along one edge	Dust on the glass or the edge of the sheet	Preview it, then delete
Only a page number, or "This page intentionally left blank"	A planned blank in a printed document	Keep it if you will print double-sided
A small stamp, signature or handwriting	Not blank	Keep it

A tip for long scans: work from the top in one pass, selecting as you scroll, and delete everything at the end. One Delete is quicker than many, and a single Undo restores the whole batch if you change your mind.

Keep the blanks you need for printing

Not every empty page is a mistake. Books, reports and some forms include blank pages on purpose so that chapters start on the right-hand side when printed on both sides. If you plan to print the file double-sided, keep those, or add them back later; see how to insert a blank page in a PDF for double-sided printing.

Other fixes while the file is open

The same screen handles the other common scan problems, so it is worth one more look before you download:

• Sideways pages. Select them and press Left or Right to rotate. For a whole file, Rotate all turns every page. Rotate PDF does the same as a separate tool.
• Pages in the wrong order. Drag them into place, or select them and use Move to start or Move to end from the ⋯ menu.
• A file that is still too big. Scans are mostly images, so removing pages helps, but the file may still be over an email or form limit. Run it through Compress PDF afterwards; our guide on how to compress a PDF to under 1 MB explains the settings.
• Only a few pages needed. If you want just part of the file, Split PDF can extract a range of pages into a new PDF.

Avoid blank pages next time

• Set the scanner to single-sided for one-sided paper. Many scanners also have a "skip blank pages" option in their own software; check its settings.
• When scanning with your phone, check the page count before you save. Image Studio shows each scanned page as a thumbnail while you work, so a stray empty capture is easy to notice; see how to scan documents with your phone.

Is my scan uploaded?

No. Organize PDF Pages reads the PDF, draws the thumbnails and builds the new file with JavaScript in your browser. Your documents stay on your device, which matters for NID copies, bank papers and medical reports. Pages are copied as they are, so the quality of the remaining pages does not change.

If the PDF is password-protected, the tool will ask you to unlock it first with PDF Unlock, then open the unlocked copy.

Quick checklist

• Previews made small enough to see many pages at once
• Even pages selected for a double-sided scan, with any content pages unticked
• Doubtful pages checked in Preview before deleting
• Planned blanks kept if the file will be printed on both sides
• Page count before and after compared once you download
• File compressed afterwards if it has to fit an upload limit
