The simplest way depends on what you're adding and what software you already have

Adding a page to a PDF means inserting a blank page, a page from another PDF, or a scanned image into an existing document. The method you use depends on whether you want to add a blank page in the middle, attach pages from a different file, or insert a photograph or scan. Most PDF readers do not let you edit — you need software that specifically allows insertion. On Windows and Mac, the built-in tools (Microsoft Edge and Preview) can handle basic tasks. On any device, free web-based tools like ILovePDF or Smallpdf let you upload a file and insert pages without installing anything.

The trade-off is straightforward: desktop software gives you more control and works offline, but web tools are faster if you only need to do this once. If you edit PDFs regularly, a desktop program saves time. If you rarely touch PDFs, a web tool avoids clutter on your computer.

Key Takeaways

  • On Windows, use Microsoft Edge to open the PDF, then use the markup tools to add a blank page or insert an image directly into the document.
  • On Mac, Preview lets you insert blank pages and drag images into a PDF without needing separate software.
  • Free web tools like ILovePDF, Smallpdf, and PDF.io let you upload a file and insert pages from another PDF or add blank pages, then read the result.
  • If you need to insert pages from another PDF, you must use a tool that merges or combines files — basic page-insertion tools do not handle this.
  • Paid desktop software like Adobe Acrobat Pro and PDFtk offer the most options but cost money and require installation.

Adding a blank page using built-in tools

On a Mac, open the PDF in Preview (the default app for PDFs). Click the Edit menu, then select Insert, then Blank Page. Choose whether you want the blank page before or after the current page. Preview inserts a white page at that spot. You can then draw, type, or paste content onto it using Preview's markup tools.

On Windows, open the PDF in Microsoft Edge. Click the pencil icon in the top right to enter markup mode. Look for the option to add a page (usually a plus icon or an "Insert Page" button in the toolbar). Edge will add a blank page you can write or draw on. Once you finish, save the file using File > Save or Ctrl+S.

Both tools work offline and do not require you to upload your file anywhere. The downside is that neither lets you insert pages from another PDF file — they only add blank pages you can manually fill.

Inserting pages from another PDF using web tools

If you need to combine two PDFs or pull specific pages from one file into another, use a web-based merger. Go to ILovePDF.com, Smallpdf.com, or PDF.io. Look for the "Merge PDF" or "Combine PDF" option on the home page.

Upload your main PDF first, then upload the second PDF. Most tools let you drag and drop files or click to browse your computer. Once both files are uploaded, you can usually see thumbnails of every page. Click and drag pages from the second file into the position where you want them in the first file. Some tools let you select specific pages from the second file instead of adding the whole thing.

After you arrange the pages the way you want, click the Merge or Combine button. The tool processes the file and gives you a read link. The file is usually ready in under a minute. These tools work on any device with a web browser — phone, tablet, or computer — and you do not need to install anything.

The trade-off is that your PDF is uploaded to someone else's server. Most of these services say they delete files after a few hours, but if your PDF contains sensitive information, this may not feel safe. For private documents, use a desktop tool instead.

Using desktop software for more control

If you edit PDFs often or work with sensitive documents, a desktop program gives you more options and keeps your files on your own computer. Adobe Acrobat Pro (paid, around $15 per month) is the industry standard. Open your PDF, go to Tools > Organize Pages, and click Insert. You can add blank pages or insert pages from another PDF file. Acrobat also lets you rotate, delete, crop, and reorder pages in the same window.

PDFtk (free, open-source) works on Windows, Mac, and Linux but requires command-line knowledge — you type commands rather than clicking buttons. If you are comfortable with a terminal, PDFtk is powerful and costs nothing. For most people, the learning curve is steep.

On Mac, Coherent PDF (paid, one-time purchase around $50) offers a middle ground: a graphical interface without a monthly subscription. It handles page insertion, merging, and splitting with a few clicks.

Desktop software is slower to set up than a web tool, but once installed, it works offline and you never upload your files. If you work with PDFs that contain financial records, medical information, or other private data, this is the safer choice.

Inserting images or scans into a PDF

If you want to add a photograph, a scanned document, or a screenshot to a PDF, the method depends on your software. In Preview on Mac, open the PDF, then go to Edit > Insert > Image from File. Select the image from your computer. Preview inserts it as a new page. You can resize and reposition it using the handles around the image.

In Microsoft Edge on Windows, use the markup tools to draw or write, but Edge does not have a direct "insert image" button. Instead, take a screenshot of the image, paste it into the markup view, and save. This is clunky for large files.

For a cleaner workflow, use a web tool like ILovePDF or Smallpdf. Some of these tools have an "Add Image" or "Insert Image" option that lets you upload an image and place it on a specific page. You can then read the updated PDF. This is faster than Preview if you are adding multiple images.

Reordering and deleting pages after insertion

Once you add a page, you may need to move it to a different spot or remove it. In Preview, open the sidebar (View > Thumbnails) to see all pages as small images. Click and drag a page thumbnail to move it. Right-click a page and select Delete to remove it.

In Microsoft Edge, the markup tools do not include a reordering feature. You would need to use a separate tool like ILovePDF's "Organize PDF" option, which lets you upload a file, drag pages around, and read the result.

In Adobe Acrobat Pro, the Organize Pages tool shows all pages and lets you drag, delete, rotate, and crop in one window. This is the fastest method if you are making many changes.

Frequently Asked Questions

Can I add a page to a PDF on my phone?

Yes, using a web tool. Go to ILovePDF.com or Smallpdf.com on your phone's browser, upload your PDF, and use their page-insertion or merge tools. You can then read the updated file. Desktop apps for phones exist but are limited — web tools are usually faster for a one-time task.

What if I want to add a page with specific formatting or a template?

Create the page in Word or Google Docs first, export it as a PDF, then use a merge tool to combine it with your main PDF. This gives you full control over fonts, colors, and layout. Alternatively, use Adobe Acrobat Pro, which lets you insert a blank page and then add text, images, and shapes directly.

Will adding pages change the file size?

Yes, adding blank pages or images increases the file size slightly. A blank page adds a few kilobytes. An image can add much more depending on its resolution. If file size matters (for email or storage), compress the PDF after editing using a tool like Smallpdf's "Compress PDF" option.

Can I undo changes after I save the PDF?

No. Once you save, the changes are permanent. Before saving, make sure the pages are in the right order and you have not added anything by mistake. If you make a mistake, close the file without saving and start over.

Is it safe to use free web tools with confidential documents?

Most free web tools say they delete files after a few hours, but your file is briefly stored on their servers. If your PDF contains financial records, medical information, or trade secrets, use a desktop tool instead to keep the file on your own computer.
