How to use
- Choose or drop a PDF. Each page is checked, and pages judged blank get a red frame and are selected.
- Review the thumbnails. Click a page to deselect it or to add one that was missed; switch to Strict or Loose if the detection is off.
- Click Delete N pages and save to download the new PDF.
Options explained
- Detection
- Strict only counts completely empty pages and keeps pages with just a page number. Standard also counts pages with only a page number or a few specks, and keeps any page with a line of text. Loose also counts pages with very little on them, such as only a header and footer.
- Content
- Shown under each thumbnail — how much of the page has content on it. Paper tint, scanner noise and text showing through from the back are not counted, and the outer 4% of the page is ignored, so scanner borders and punch holes do not matter.
- Manual changes
- Pages you click keep your choice, even if you switch the detection level.
When it helps
Duplex scans. A duplex scanner creates a page for the back of every sheet, so a single-sided original ends up with a blank page after every page. Remove them here; if the front and back sides were scanned as separate files, Merge Duplex Scan can combine them.
Blank pages after converting from Word or Excel. Page breaks and empty paragraphs at the end of a table often leave a whole empty page in the PDF. Standard finds them.
Pages with only a page number. Standard treats them as blank. To keep them, switch to Strict or click the page to deselect it.
Frequently asked questions
Will grey or yellowish scanned paper count as content?
No. The most common colour on the page is taken as the paper colour, and only areas clearly darker (or lighter) than it count as content. Grey or yellow paper and slides with a dark background are handled correctly.
What about text showing through from the other side?
Show-through is usually faint and is not counted, so the page is still treated as blank. If it is dark enough to be kept, just click the page to select it.
Does the page order change?
No. The remaining pages keep their order, orientation and content. Bookmarks and links that pointed to deleted pages stop working.
Are my files uploaded?
No. Checking and deleting happen in your browser and the file never leaves your device.
