Delete blank PDF pages
Drop pages with nothing drawn on them. Runs entirely on your device.
Runs on your device. The file is never uploaded.
Delete blank PDF pages asks pdf.js for each page's operator list and keeps only the pages that draw at least one operator, saving the rest as -noblanks.pdf. It tells you how many went, or reports no blank pages found. The output is a fresh document built by copying pages, so bookmarks and form fields do not survive.
Questions
What counts as blank?
A page that paints nothing at all, zero drawing operations, as reported by pdf.js. Not "no text": a page with only a faint scanned background or a stray line is not blank, and is kept.
Will it catch blank pages in a scan?
Often not, and that is deliberate. A scanned blank sheet is usually a full-page image of off-white paper, which is something drawn. Removing it would mean guessing at a whiteness threshold, and guessing wrongly deletes a page of someone's document.
How do I know what it did?
It tells you: "removed 3 blank pages", or "no blank pages found" when your document was already clean and it hands the file back.
What if every page is blank?
It refuses, "refusing to produce an empty PDF", rather than handing back a document with nothing in it.
