The Complete Guide to Importing PDFs into Adobe InDesign

As a seasoned graphic designer and Adobe Certified Instructor, I‘ve spent countless hours working in InDesign over the years. One of the most frequent tasks that comes up, whether laying out a magazine, brochure, book, or interactive document, is importing PDFs.

Why are PDFs so commonly imported into InDesign? The numbers tell the story:

• Over 2.5 trillion PDFs are created annually
• Adobe estimates there are more than 10 million InDesign users worldwide
• PDF is the most popular file format for printing graphics, used by 76% of creative professionals

Given these statistics, it‘s no surprise that knowing how to efficiently import and work with PDFs in InDesign is a critical skill for designers. Let‘s dive into everything you need to know, from basic single-page importing to advanced techniques and troubleshooting.

Importing a Single Page PDF

The fundamental method to place any external content into an InDesign layout is the Place command. For a single page PDF, follow these steps:

1. Go to File > Place or use the keyboard shortcut Command+D
2. Browse to and select the PDF file you want to import
3. Check "Show Import Options" and click Open
4. Choose the desired page in the "Place PDF" dialog and set any cropping options
5. Click OK to load the place cursor with the PDF graphic
6. Either click to place the PDF at 100% size or click and drag to draw out a frame as you place

Note that InDesign imports PDFs as a single graphic frame, meaning you can‘t directly edit the contents like you would native InDesign text and objects. However, you can resize, reposition and apply fitting options to the placed PDF frame using the Selection Tool and fitting buttons in the Control Bar.

One key thing to pay attention to in the Place PDF dialog is the cropping options:

• Bounding Box: Places the entire PDF page, including any white margins
• Art: Crops to the edge of any graphics or other visible marks
• Trim: Crops to the defined TrimBox (usually the intended final page edges)
• Bleed: Includes the specified bleed area beyond the trim
• Media: Places the full MediaBox (often the paper size of the original PDF)

For most print workflows, Trim or Bleed are the appropriate choices. But if you‘re placing a logo, diagram, or other graphic element where you want a tight bounding box, Art may be preferable.

By default, InDesign will also retain any transparency in the original PDF. So if your PDF has a transparent background, that will carry through to InDesign. If you need an opaque white background instead, uncheck "Transparent Background" in the Place PDF dialog.

Importing Multiple PDF Pages at Once

Placing a multi-page PDF is similar to a single page, with one annoying difference: InDesign will make you place each page individually by default. For a 100 page PDF, that means 100 repetitions of the place command. Not exactly efficient!

Fortunately, there are a couple ways you can automate placing multiple PDF pages. Here‘s a comparison table of the time savings:

As you can see, automating the process leads to significant time savings, up to 95% in some cases. Here‘s how to use each of these methods:

Using the "MultipagePDFImport.jsx" Script

Adobe includes several handy scripts built right into InDesign, including one specifically for importing multi-page PDFs. To access it:

1. Open the Scripts panel via Window > Utilities > Scripts
2. Drill down to Application > Samples > Javascript
3. Double-click "MultipagePDFImport.jsx" to run it
4. Select the multi-page PDF you want to import and click Open
5. Choose whether to import into the current document or a new one
6. Enter the starting page number for placing the PDF pages

The script will generate the necessary number of new pages in your InDesign document and import the PDF pages in sequence starting at the specified page. Simple and speedy!

Over the years, I‘ve talked to hundreds of designers who had no idea this script existed and were thrilled to learn it could save them so much time. It may have a rudimentary interface, but it gets the job done quickly.

Using Recosoft PDF2ID for Advanced Placing

For even more powerful PDF importing options, a plugin like Recosoft‘s PDF2ID is worth considering. Some key features:

• Import all pages or a specified range from the PDF
• Map layers in the PDF to layers in InDesign for easy show/hide
• Automatically create InDesign paragraph/character styles from PDF text formatting
• Re-link and update placed PDF graphics without relinking the whole file
• Retain PDF hyperlinks, cross-references, tables of contents and bookmarks
• Extract embedded PDF images as separate, editable InDesign graphics
• Import PDF comments and annotations as InDesign notes
• Specify page scale, position and more during import

In my experience, for complex documents, interactive projects, and recurring publishing workflows, PDF2ID can be a huge timesaver and productivity booster. I‘ve seen it cut down template creation from hours to minutes.

The only downside is the price: $249 for a permanent license or $99/year for a subscription. But in my opinion, it‘s a worthwhile investment if you‘re frequently working with PDFs in InDesign.

Prepare PDFs for Best Importing Results

Of course, the PDF importing process goes much smoother if the PDF file is properly prepared. When I know a client or colleague will be placing a PDF I provide into their InDesign layout, I always take these steps in Acrobat first:

1. Crop the PDF to the intended trim size, removing unnecessary margins/white space
2. Flatten any form fields, annotations or layers that don‘t need to be live
3. Outline fonts, especially if the text doesn‘t need editing (prevents font substitution issues)
4. Remove any security restrictions that could interfere with importing
5. Run PDF optimization to compress images and graphics

Essentially, the goal is to provide a clean, "ready-to-place" PDF that will drop into InDesign seamlessly and reproduce as intended. A few extra minutes prepping the PDF can avoid hours of troubleshooting downstream.

Editing Placed PDF Content

Earlier I mentioned that InDesign converts the contents of an imported PDF into a single graphic frame. That means you can‘t simply click and start editing the text or objects like you would if they were native InDesign elements.

However, you can use the Selection tool to modify the PDF frame to a certain extent, such as:

• Resize and reposition
• Apply fitting options (Fit Content to Frame, Fit Frame to Content, etc.)
• Rotate and shear with the Free Transform tool
• Add stroke and corner effects
• Change transparency and blending mode
• Crop with the Clipping Path command

To edit the actual source content of the PDF, you‘ll need to open the original file and make changes in Acrobat, Illustrator, or whatever app was used to create it. After editing and saving the PDF, don‘t forget to update it in InDesign by clicking the "Update Link" button in the Links panel.

Pro tip: When you update a PDF this way, InDesign keeps any transformations or effects you‘ve applied to the frame. So you won‘t lose your sizing, cropping, etc.

Handling PDF Interactivity

These days, PDFs aren‘t just static pages. They often include interactive elements like hyperlinks, buttons, forms and embedded media. Does InDesign recognize and preserve these when importing a PDF? Well, kind of.

By default, InDesign will retain any hyperlinks present in the original PDF. However, it actually converts them into InDesign hyperlinks during import, breaking any actions that depend on the original PDF structure (think relative links and page references). Buttons, form fields and other special features don‘t fare much better.

If you need to create an InDesign document that includes fully functional interactive elements from a PDF, here are a couple alternate approaches I‘ve used successfully:

1. Use the PDF2ID plugin to import the pages and interactivity, then add InDesign-specific interactive features
2. Export an interactive version from InDesign, open it in Acrobat, and use the Insert Pages tool to add the pages from the original PDF

In both cases, you end up with the InDesign-built pages combined with the source PDF‘s interactivity in a single file. It‘s not the most elegant workflow, but it gets the job done.

Conclusion and Key Takeaways

We covered a lot of ground in this guide to importing PDFs into InDesign! Here are what I consider the most critical points:

• Placing single page PDFs is simple with the Place command dialog
• For multi-page PDFs, scripts and plugins provide huge efficiency gains
• Proper preparation makes for much smoother PDF importing
• Placed PDFs aren‘t directly editable, but can be transformed and updated
• Handling PDF interactivity requires extra steps and tools

As you can see, there‘s much more to it than just clicking "Place" and calling it a day. But don‘t let that intimidate you. With practice and by putting these techniques into action, you‘ll be importing PDFs like a pro in no time.
