Best Practice

When flattening a PDF with a flatten feature on PDF Reader Pro or Adobe Acrobat, there are certain steps that are considered best practice. It's always a good idea to take into account the following checklist when flattening your PDF:

• Backup Your Original: Always keep an unflattened copy of your PDF. It provides flexibility in case you need to make changes later. The PDF flattening process prohibits further editing of your newly saved PDF documents.
• Check the Flattened Version: After using the Flatten PDF feature, always open the new version to ensure everything appears element rich and as expected on your PDF forms.
• Avoid Multiple Flattening: Every time you flatten a PDF, you risk compromising its quality slightly. Minimize the number of times you perform the process to maintain a good file size.

Reasons to Flatten a PDF

While there are myriad reasons you may need to flatten a PDF, there are some key aspects to keep in mind. These can also provide solutions to certain problems you might encounter when sharing, editing, or saving PDF documents. Scenarios you may encounter include:

• Consistency: Flattening ensures your document looks the same across all devices and platforms, preserving fonts, colors, and layouts.
• File Security: Flattening can prevent others from making unauthorized changes or annotations. Taking extra file privacy measures is always a good idea, especially to control how and when others can access fillable PDF files like business documents.
• Reduced File Size: Flattening often reduces the overall size of the PDF, making it easier to share or store. This can be helpful in the case of sharing information via mobile device or when larger storage applications like Google Drive are not applicable.
• Printing Process: Some printers or printing services may require flattened PDFs to ensure the document prints correctly. Flattening the PDF can help the two devices communicate.
• Fillable PDF Forms: In the case of fillable forms where others need to input their information such as their digital signature, you'll want the document creators to feel safe in the knowledge that their information isn't being copied. Flattening a PDF prevents third-party users from using editing tools to change the fillable fields.
  
  

The Importance of File Security When Flattening a PDF

PDF files have become the universal standard for document sharing and archiving due to allowing complex documents to maintain a consistent appearance across platforms and reduce a document's size while still providing a high-resolution file.

Many PDF files carry sensitive information, whether it's a business contract, a design mockup, or personal data. Hence, as PDFs undergo modifications, such as flattening, it is imperative to ensure file security (and, importantly, file quality) remains uncompromised. Some crucial reasons to think about file security when flattening a PDF include:

• Consistency Across Platforms: One of the main reasons to flatten a PDF is to ensure consistency. Flattening helps to maintain the visual and informational consistency of the document by merging layers, comments, and annotations into a single layer. However, if security isn't maintained during this process, there's a risk that these elements might be altered, deleted, or incorrectly merged.
• Prevention of Unauthorized Edits: Flattened PDFs are harder to manipulate since annotations and form fields become a part of the document's content, rather than overlay elements. When you secure the flattened PDF properly, it further ensures that no unauthorized alterations can occur post-flattening.
• Preventing Data Breaches: Flattening processes, if not handled securely, could lead to temporary files or backups being created without the user's knowledge. These files might be accessible to third parties, leading to potential data breaches of the editable fields.
• Unintended Metadata Exposure: Often, users overlook the metadata embedded within a PDF, which can contain sensitive details, such as the author's name, document change history, or even location data. Ensuring file security means being mindful of this metadata and managing it appropriately during the flattening process.
• Ensuring Compliance and Legal Standards: Many industries, especially finance, health, and legal sectors, have stringent regulations around document security. Ensuring file security during any document modification process, including flattening of the entire PDF file, is necessary to remain compliant with industry or legal standards.
• Professionalism in Document Presentation: A secure flattening process ensures that the document's appearance remains consistent and of high quality, presenting a professional image to clients, colleagues, or any other stakeholders.
• Instilling Trust and Reliability: Businesses and individuals that prioritize document security are seen as trustworthy and reliable. Any compromise in file security, especially during modifications, can tarnish this image.
  
  

Best Practices for File Security During Flattening

If your main reason for flattening your PDF documents is file security, there are a few main factors to consider to optimize the safety of your information. These include the following safeguarding measures: 

• Use Reliable Software: Always use reputable PDF software, whether it's for editing, flattening, or securing the file. Free or unfamiliar software might not provide the level of security required.
• Encrypt Your PDF: If the PDF contains sensitive data, consider encrypting it with a strong password. This adds an extra layer of protection against unauthorized access.
• Regularly Update Software: Cyber threats evolve, and software developers regularly patch vulnerabilities. Ensure your PDF software is always updated to the latest version to benefit from these security enhancements.
• Backup Original Files: Always keep an original, unflattened version stored securely. This ensures you have access to the initial document should any security issues arise post-flattening.
  
  

While flattening a PDF is essential for various practical reasons, it should never come at the cost of compromising file security. By understanding the importance and implementing secure practices, you can maintain the integrity and confidentiality of your PDFs during the flattening process.

The PDF flattening process can be an essential step in your document preparation. Following the above steps and maintaining a keen awareness of quality is crucial. Our guide is designed to help you flatten an entire document confidently while using the excellent tools provided by PDF Reader Pro.
