How to Insert Pages Into PDF
When assembling documents, you frequently need to insert additional pages at specific positions—adding a signed page into a contract, inserting an appendix before the references section, or adding a new chapter between existing ones. Unlike merging, which appends files end-to-end, inserting lets you place pages precisely where they belong within an existing document.

Upload your base PDF
Open the Insert Pages tool and upload the primary document—the one that will receive new pages. The tool displays all pages as numbered thumbnails.
Upload pages to insert
Upload a second PDF containing the pages you want to insert. You can also upload images, which will each become a single PDF page. The source pages appear in a separate panel.
Choose the insertion point
Click between any two page thumbnails in your base document to set the insertion point. A blue line indicator shows exactly where the new pages will go. You can also type a specific page number.
Select which pages to insert
From the source document panel, select all pages or just specific ones. Drag to reorder them before insertion if needed. The preview updates to show the combined result.
Review and download
Scroll through the merged result to verify page order and content placement. The total page count updates automatically. Download the combined document when everything is in place.
Pro Tips
- 💡 To insert a signed page, scan only the signed page to PDF, then insert it at the exact position replacing the unsigned version—delete the original unsigned page afterward.
- 💡 When inserting pages from a document with different page sizes, the inserted pages retain their original dimensions. Use the Resize tool afterward if you need uniform sizing.
- 💡 Insert blank pages before new sections to create natural chapter breaks in longer documents.
- 💡 If you're building a document from multiple sources, plan your insertion order from back to front—this way, page numbers don't shift as you insert, making it easier to target the right position.
