Blank pages often come from scanning and export workflows
Common examples include back sides of scanned sheets, separator pages in office copier jobs, extra pages created by print-to-PDF workflows, or slide handouts that ended with an empty sheet. These are usually safe candidates for removal.
Check whether the page is truly blank before deleting it
A page can look empty at first glance but still contain faint scan marks, page numbers, stamps, or hidden content near the edges. Manual review with page previews is safer than assuming every near-empty page should disappear.
Manual review is different from automatic blank-page detection
Some PDF tools promise to detect blank pages automatically, but that depends on their threshold and on how the source PDF was created. A browser-side cleanup flow like 删除 PDF 页面 is explicit: you review the pages yourself and remove only what you actually want gone.
Remove blank pages without changing the rest of the document
If the rest of the file is already correct, page removal is usually cleaner than splitting and rebuilding the PDF. You keep the remaining pages in order and export a trimmed copy instead of rewriting the whole workflow.
Blank-page cleanup is common before sharing or merging
It is often worth cleaning blank pages before you send a report, deliver a scanned packet, or combine several PDFs. Otherwise those empty sheets will keep traveling into merged files and make the final result feel sloppy.
