Frequently Asked Questions
What is a PDF file?
PDF (Portable Document Format) is a file format that preserves a document's visual appearance — fonts, layout, images — exactly the same on every device and operating system. Unlike Word documents that reflow based on software settings, a PDF looks identical whether opened on Windows, macOS, iOS, or Android.
Why are PDFs used for documents?
PDFs are used because they guarantee consistent presentation. A legal contract, invoice, or official form printed from a PDF looks exactly as intended — the right fonts, the correct layout, the proper signatures. Email recipients cannot accidentally alter a PDF's appearance by having different fonts or software versions installed.
How do I open a PDF on any device?
PDFs open with built-in tools on every modern device: Preview on macOS, Edge or Chrome on Windows, Files on iOS, and any browser on Android. No additional software is required. For advanced features like form filling and annotation, Adobe Acrobat Reader is free to download.
How do I create a PDF?
On macOS: File → Print → PDF → Save as PDF in any application. On Windows: File → Print → Microsoft Print to PDF. In Microsoft Word, Google Docs, or LibreOffice: File → Export as PDF or Download as PDF. Most web browsers can print any webpage to PDF using Ctrl+P / Cmd+P.
What is the difference between PDF and DOCX?
DOCX (Word document) is an editable format — layout can change based on software, fonts, and screen size. PDF is a fixed-layout format — it looks the same everywhere. Use DOCX when you need to continue editing; use PDF when you need to share a final version that must look correct on any device.
