Batch add a blank page to odd PDFs
in one go.
Printing double-sided? A PDF with an odd number of pages leaves the last sheet half empty and can mix up the next document. This tool adds a blank page at the end of every PDF that needs one, so each file ends on a full sheet. Everything runs in your browser; nothing is uploaded.

Adds one blank page (same size as the last page) only to PDFs with an odd page count. PDFs that already have an even count are returned unchanged.
How to add blank pages to PDFs in batch
- Drop in every PDF you want to prepare for duplex printing.
- Review the list of files.
- Click Add blank pages. Each file is checked and processed one at a time, right in your browser.
- Download one finished file, or click Download all (ZIP) to get everything at once.
Why batch add blank pages with VitePDF
- Print a whole folder double-sided without a document starting on the back of the previous one, instead of fixing each file by hand.
- Nothing is uploaded — your documents never leave your device.
- Nothing else changes: existing pages, links, form fields and bookmarks stay exactly as they were.
Frequently asked questions
Which PDFs get a blank page?
Only those with an odd number of pages. One blank page is added at the end, with the same size and orientation as the last page, so the file ends on a complete sheet.
What happens to PDFs that already have an even number of pages?
They are returned as they are, without any change.
What happens to my original files?
They are never modified. You download new copies.
What about password-protected PDFs?
They are flagged and skipped. Remove the password first with Batch unlock PDF, then edit them.
Are my files uploaded anywhere?
No. The PDFs are processed entirely in your browser tab, so they never leave your device.
