About replace PDF pages

Swap one or more pages in a PDF with pages from another file — without uploading anything. Select matching pages in both documents, preview the result, then download a new PDF from your browser.

How it works

Upload a base PDF and a replacement PDF. Select pages to replace in the original, then select the same number of pages from the replacement file. Dockzio maps them in ascending order, builds a new document, and keeps unselected original pages intact.

When to replace pages

Use this to update a cover page, swap a corrected exhibit, refresh a signature page, or drop in redesigned slides without rebuilding the whole file.

Limits

Upload two PDFs up to 25MB each. You must select the same number of pages in both files. Bookmarks / outlines are not preserved (pdf-lib cannot copy them). Password-protected PDFs are not supported — unlock them first.

Privacy first

Everything is processed locally in your browser with pdf-lib. Your documents are never sent to a Dockzio server.

FAQ
