Get the rebuilt PDF with blank pages inserted exactly where you asked.
Tips
- “Every N pages” builds workbooks in one click. Note space after every slide or section, no manual repetition.
- Number pages after inserting blanks, not before — use Add Page Numbers on the finished file.
- Same-as-document size is the safe default. Mixed sizes look broken in thumbnail strips.
- Added one by mistake? Delete PDF Pages removes it just as fast.
Frequently asked questions
Is Add Blank Page to PDF free to use without signup?
Yes. EzySize’s Add Blank Page to PDF tool is free to use without creating an account. Advertising may appear on this page; the tool remains free to use. Use the controls above and check the result against your requirements.
How do I add a blank page to a PDF?
Drop your PDF, choose where the blank pages go (start, end, after a specific page, or after every N pages), pick the page size, and hit Add blank pages. The new PDF downloads with the blank pages inserted — all in your browser.
Can I add many blank pages to a PDF at once?
Yes. “After every N pages” inserts a blank page throughout the document in one pass — for example, after every 5 pages of a 50-page document, you get 10 blank pages in a single run.
What size will the inserted blank pages be?
You choose: same size as your document (the default), A4, or US Letter. “Same as document” copies the first page’s dimensions, so mixed-size documents stay consistent.
Will blank pages mess up my page numbers?
Blank pages become real pages of the document, so any printed page numbers after the insertion point shift by the number added. If your document has numbered pages, add the blanks first, then run the Add Page Numbers tool so numbering stays correct.
Can I insert a blank page after a specific page?
Yes — choose “After page N” and type the page number. The blank page lands immediately after it, pushing the rest of the document down by one.
Is my PDF uploaded to a server?
No. The whole operation happens inside your browser with a local PDF engine. Your document never leaves your device, which also means the tool works offline once the page has loaded.
I added a blank page by mistake. Can I remove it?
Yes — open the result in the Delete PDF Pages tool, tick the blank pages, and remove them. Or just re-run this tool on your original PDF.
Does it work on scanned PDFs?
Yes. Blank pages are inserted at the document level, so scanned image pages, text pages and mixed documents all work the same way.
Can I add blank pages to a password-protected PDF?
Not directly — protected files can’t be opened without the password. Unlock the PDF first, then add your blank pages.
Why would anyone add blank pages to a PDF?
Common reasons: note-taking space in handouts, forcing chapters to start on odd pages for duplex printing, placeholder pages for content arriving later, and separator pages between sections of a report.
Will adding blank pages make my PDF file much bigger?
Barely. A blank page is vector-only — no images, no text — so each one adds only a few hundred bytes. Even ten blank pages in a 5MB document are invisible in the final size.
How do I force chapters to start on odd pages for duplex printing?
Count the pages of each chapter: if a chapter ends on an odd page, insert one blank page after it so the next chapter starts on an odd page (the right-hand side when printed double-sided). Use the “after page N” mode and repeat for each chapter break.
Do bookmarks, links and form fields survive?
Inserted pages shift everything after them, and document-level items like bookmarks, form fields and annotations may not survive the rebuild. Page content is always preserved — but check the output before sending it on if your document relies on those extras.
Can I add blank pages at the start AND end in one go?
One position mode runs at a time, so pick the most common spot first, download the result, and run that file through again for the second spot. It takes seconds, and everything stays in your browser.
