Insert blank pages into any PDF — at the beginning, at the end, or at any specific position between existing pages. Fast, private and fully browser-based.
Select a PDF to add a blank page — or drag & drop
Dudi Add Blank Page is a fast, 100% free, browser-based tool from Dudi PDF Editor that inserts blank pages into any PDF document in seconds. Whether you need a blank page before a cover for double-sided printing, a blank page between chapters for a cleaner layout, a blank page at the end for notes or signatures, or several blank pages in the middle to make a print-ready booklet, this tool does all of it without installing software, creating an account, verifying an email or paying any hidden fee. Unlike most online PDF editors, your file is never uploaded to a remote server. The entire process runs inside your browser using the well-known pdf-lib JavaScript library — your PDF is read from your device, the blank pages are inserted in memory, and the finished file stays on your device until you press the Download button. That means your confidential reports, legal documents, academic papers, invoices and internal company files never leave your computer or phone. There is no signup, no watermark added by us, no daily limit and no page-count restriction beyond your device's memory. Dudi Add Blank Page gives you three insertion options so you can put a blank page exactly where you need it. Beginning inserts a blank page before page 1 — perfect when you want a cover sheet or a dedication page at the very front. End inserts a blank page after the last page — useful when you want a notes page, a signature page, or extra space before the back cover. Between lets you choose any position — enter a number and the blank page is placed right after that page, before the next one. You can insert more than one blank page in a single action by setting the count (up to 50), which is very handy when building booklets, workbooks, exam papers or chapters where multiple blank sheets are needed. You can also choose the size of the blank pages. Match page 1 keeps the new pages the same size as the first page so the final PDF looks uniform. Match previous page uses the page immediately before the insertion point, which is ideal when a document mixes portrait and landscape pages. You can also force A4 or US Letter if you want consistent output regardless of the source. The original PDF pages are never modified — they are copied exactly as they are, with all fonts, images, hyperlinks, annotations and form fields preserved, so there is zero quality loss. The finished file opens correctly in Adobe Acrobat, Chrome, Edge, Safari, Firefox and every common PDF reader, and the blank pages behave exactly like normal pages, so you can print them, sign them, merge more content, or add page numbers on top. Because the tool never downloads automatically, nothing is saved to your disk until you choose it: after the blank pages are inserted, a Download button appears and you decide when to save the file. The downloaded file is always named Dudi PDF Editor Add Blank Page.pdf, and if you add blank pages to another file in the same session it becomes Dudi PDF Editor Add Blank Page (2).pdf and so on, so your files stay clearly identifiable. The layout is fully responsive, so the three option cards, the number fields and the action buttons all stay easy to tap on a small Android phone as well as on a large desktop monitor. After the first page load the libraries are cached, so the tool often keeps working even on a weak connection. Remember that if your PDF is protected with an open password, you should first unlock it with the Dudi Unlock PDF tool. If you need more tools, Dudi PDF Editor also offers Delete Pages, Merge PDF, Split PDF, Rotate PDF, PDF Page Numbers, Sign PDF, Protect PDF, Unlock PDF, Watermark PDF, Word to PDF, JPG to PDF, editing, cropping, OCR, image conversion and many other privacy-first utilities that all run locally in your browser with the same no-upload guarantee.
