About insert blank pages
Add blank pages before or after any page — or several at once — without uploading anything. Choose size, orientation, and color, preview the result, then download a new PDF from your browser.
How it works
Upload a PDF, select one or more pages as insert positions, choose Before or After, set how many blanks to add at each position, then apply. Dockzio builds a new document with blanks inserted and original pages kept in order.
When to insert blank pages
Use blanks for covers, section dividers, signature pages, print duplex padding, or notes space between chapters — especially when you need matching paper size across mixed-size documents.
Limits
Upload one PDF up to 25MB. You can insert 1–20 blank pages at each selected position. Password-protected PDFs are not supported yet — unlock them first, then try again.
Privacy first
Everything is processed locally in your browser with pdf-lib. Your documents are never sent to a Dockzio server.
