To add pages to a PDF, you can use PDF.net online, Preview (on Mac), and Python.

Inserting new pages in existing files is quite beneficial when editing, merging, or creating fillable forms in PDFs, as you can transfer or distribute content to new pages for better readability. Besides that, you can also use new pages to divide merged documents or add forms.

However, some methods for PDF page insertion can be unreliable due to cheap software or low safety standards. To help you avoid such issues and keep your documents safe, we present the top three easiest and most effective ways to add pages to PDFs with some extra tips for maximum leverage.

How to Add Pages to a PDF Using PDF.net

To add pages to a PDF online using PDF.net software, you should upload your document to our website, use the tool to insert pages, and download the updated file.

Let’s examine this process in detail:

#1. Visit Our Website and Upload Your Document

Go to the PDF.net homepage, hover over the More Tools drop-down menu, and select Add Pages. Then, drag and drop the document into the Drop file here to add images box, or click Choose file to upload it manually.

#2. Use the PDF Page Inserter

After uploading your file, a new page will open, and you will be able to choose between transferring pages from existing documents or adding blank pages to your PDF. Click the + button for a blank page, or click the page icon labeled Add file to upload another PDF and add one or more of its pages to the first document.

If you decide to insert a blank page into a PDF, it will appear in the preview, where you can select the page and move it to the left or right using the arrows from the toolbar to position it.

On the other hand, there is also a page preview option for documents whose pages you want to transfer to your main document. You need to upload a new file, select pages from the preview, and click Add Pages at the bottom right. Once you do this, the system will merge them with your main file.

As with the blank page, you can move the new pages left or right to adjust their position. Once you’re happy with it, click Add Pages to PDF in the lower-right corner to finalize this process.

#3. Download Your File

The final step is to save your document by clicking the Download button in the upper-right corner. The download process is automatic and will take only a few seconds.

How to Add Pages to a PDF Using Preview

To add pages to a PDF using Preview, you should follow these steps:

  1. Right-click the file you want to add pages to, choose Open With, and select Preview.

5. Click File and select Save.

Saving the file

How to Add Pages to a PDF Using Python

To add pages to a PDF using Python, you should use Aspose.PDF for Python on .NET.

Here are the steps to do so:

  1. Make a Document class object using your main PDF document.
  2. Use the specified index for the insert method of the PageCollection, a smaller part of the Collection class.
  3. Deliver the file with new pages using the Save method.

While this procedure isn’t long, it is undoubtedly one of the most complex ones, as it requires knowledge of Python coding.

4 Tips for Managing Multi-Page PDFs

Page order, position, relevance, and the overall document size are the most important aspects for managing multi-page PDFs. Luckily, we offer PDF tools that can enhance each of these.

Let’s see what they are and how to use them:

#1. Rearranging Pages

After you add or insert pages into a PDF, you may need to make some adjustments to your document to keep it cohesive and readable. To do so, you can rearrange PDF pages with our tool. The software provides a clear preview of all the pages in your document, allowing you to zoom in and out on each one and make any necessary modifications to page order.

Once you see all the pages and decide where to position them, you can select one, several, or all of them and use the left or right arrow icon to move them. You can also duplicate pages with one click, if needed, and save the reordered file to your drive.

#2. Rotating Pages

Pages from other documents may be upside down or in landscape mode instead of the portrait one, or vice versa. To help you align them perfectly, you can use our page rotation tool.

This software is simple; all you should do is upload your document to PDF.net, open the rotator, select pages, and use the Rotate left and Rotate right buttons to switch page orientation. This makes your file neater and more readable and helps you create official documents with strict page standards.

#3. Deleting Unwanted Pages

You may add pages containing additional information about a particular topic, but some parts may overlap with existing data on other pages. In such cases, you can remove unwanted pages from your PDF.

The simplest way to do so is to use either the PDF.net rearrange or rotation tool. Both of them allow you to preview and select pages, which you can remove by clicking the trash bin icon.

#4. Compressing Large PDFs After Merging

Adding a PDF to another PDF or inserting pages can result in large documents that may be challenging to share, upload, or use. Instead of constantly splitting and combining PDF files again to bypass size limits, you can shrink them using our compression tool.

PDF.net offers lossless compression, which helps you avoid the ‘split and merge PDFs’ cycle, resulting in smaller documents with the original formatting and quality. Most importantly, you can transfer files quickly and easily after this process; just upload your document, use compression software to resize PDFs, and download the shrunk file.

Why Use PDF.net For Editing and Organizing Your PDF Files?

You should use PDF.net for editing and organizing your PDF files because it’s fast, secure, and easy to use. For instance, you can add page numbers to them for better navigation.

Adding bookmarks to PDFs is another similar process to help you make all the chapters or titles of your document one click away. Lastly, you can edit text, annotate your file, chat with PDF, and perform many other actions—all on PDF.net.

Unlike free PDF editors, where safety is at risk, we use strong encryption to protect your documents and data. This helps us ensure a maximum experience for our users and gain their long-term trust!
