Resizing a PDF image improves shareability, display, and file size, but you must balance quality, formatting, and aspect ratio. Tools like DocFly make the process simple, while batch options handle multiple files. Common challenges include quality loss, distortion, larger file sizes, and layout shifts, which can be fixed by careful resizing, locking proportions, compressing, and adjusting layouts. Always save in high resolution, optimize cautiously, and keep a master copy for future edits.

Learning how to strikethrough text in PDF files is a fundamental necessity for efficient document collaboration and revision, enabling users to mark content for deletion or suggest corrections without permanently altering the source text.  PDF files are primarily designed for fixed document presentation, making permanent editing inherently challenging. Consequently, modern PDF viewers and editors rely on robust annotation tools like the strikethrough function, which is critical for reviewers working on legal contracts, academic papers, or technical manuals, allowing them to clearly communicate changes to collaborators.

Restricting interaction with a PDF is essential for maintaining document security, preserving intellectual property, and ensuring the integrity of sensitive information when sharing files digitally.  Below we detail the reasons why these limitations are necessary and explore the technical methods, including encryption and flattening, used to secure PDF documents against unauthorized changes.

You can make a fillable form in Excel by enabling the developer tab, designing a clear layout, adding interactive controls (like drop-downs and checkboxes), and protecting the sheet so only input fields can be edited. Test the form for accuracy, follow best practices for simplicity and usability, and convert it to PDF if you need an easy-to-share, consistent version. Creating fillable forms in Excel is a practical way to streamline data collection and management. Excel provides the flexibility to design custom forms that are easy for users to complete when gathering survey responses, tracking employee information, managing project details, or...

Most successful tech innovations over the course of history start from humble beginnings. Microsoft Word's ascent from a far-off concept to the most popular word processing programme in the world was similarly improbable.  In 1975, childhood friends Bill Gates and Paul Allen founded a small computer software company called "Micro-Soft" (it took them a few years to slash the hyphen). With big dreams and little funding, they started in Albuquerque, New Mexico before moving their headquarters up to their hometown of Bellevue, Washington in 1979. At the time, electric typewriters were the most state-of-the-art word processing tool. Just a small handful...

Adding page numbers to a PDF is a practical step for organizing, referencing, and presenting professional documents. Whether you're preparing reports, eBooks, or contracts, numbered pages help users navigate with ease, ensure consistency, and make collaboration more efficient. While many PDFs are created without page numbers (especially those generated from scans or exported files) you can still add them after the fact. In this guide, we’ll walk you through how to add page numbers to a PDF using DocFly, as well as explore alternative tools and methods. We’ll also share key considerations for customising your page numbers properly.

PDFs are widely used across industries for sharing documents because they preserve formatting and are easy to view across devices. However, PDFs are not just for reading, they’re also an essential medium for collaborative review. Adding comments and annotations to a PDF enables teams to share feedback, mark up changes, and improve document accuracy and quality. Whether you're editing a contract, reviewing a design draft, or giving feedback on a research paper, PDF annotations make remote collaboration clearer and more effective.

Losing access to a critical PDF document, whether it’s an accidental deletion, software crash, or corruption, can be frustrating, especially when the file contains sensitive information. Fortunately, there are several methods available to help you recover unsaved, deleted, or even damaged PDF files.  Whether you're working with PDFs in a business environment or managing personal documents, the below guide will walk you through your recovery options and provide actionable tips to prevent future loss.
