JavaScript in PDFs can lead to compatibility problems with OnBoard, potentially causing book build failures. 

Additionally, JavaScript in PDFs poses security risks by executing malicious code and may compromise user privacy.

Removing JavaScript from PDFs ensures enhanced safety and prevents issues with OnBoard book builds. 

Read below to learn how to remove JavaScript from PDFs.

Print to PDF

"Print to PDF" will create a new PDF document with the JavaScript removed. Review the instructions below to learn how to Print to PDF.

Print to PDF on a Computer: 

1. Open the original PDF on your computer.
2. Go to "Print".
3. Under Printers, select "Print to PDF."

4. Go to the bottom of that same popup, and you'll see "Orientation". Change it from "auto portrait/Landscape" to just "landscape" or just "portrait" according to how you want the document to display (This step is only necessary if there is an issue with the file orientation).
5. Press Print (you aren't actually printing, this will pull up a save screen). 
6. Once the document is saved, upload the new simplified .PDF version to OnBoard in place of the original file.

Print to PDF from a mobile device: 

Android

1. Tap Share, then choose Print.
2. Set the printer as "Save as PDF" then click the Download PDF button.
3. Choose the location to save your file, then click Save.

iOS

1. Tap the Share icon, then choose Print.
2. Open the document preview, then tap the Share icon on the preview.
3. Choose the location to save, and your document will be converted to PDF.

Important Note: Print to PDF also flattens PDFs and might cause hyperlinks contained within the document to no longer function.

Disabling JavaScript in PDFs

JavaScript functionality can be turned off in Adobe Acrobat, which can disable JavaScript when creating PDFs in the future.

Review Adobe's article on JavaScripts in PDFs as a security risk or search Adobe's help site for more information.
