What Is a PDF?
A PDF is a document format designed to keep pages looking consistent across devices, apps and operating systems.
Quick answer
PDF stands for Portable Document Format. It is commonly used for forms, reports, scans, contracts, invoices and documents that should look the same when opened or printed.
How to think about it
- 1Use PDF when page layout matters.
- 2Use editable formats when text needs to be rewritten.
- 3Use image formats when the page is only a visual asset.
Why PDF exists
PDF was created to make documents portable. A PDF can include text, images, fonts, page sizes, links, forms and metadata in one file.
That portability is why PDFs are used for invoices, legal documents, school submissions, manuals, resumes, tickets and scanned records.
What a PDF is good at
PDF is good when a document should be viewed or printed predictably. It is less ideal when the main job is collaborative writing or live editing.
- Preserving page layout.
- Combining several pages into one file.
- Sharing forms, scans and reports.
- Archiving documents for later review.
Example
A photographed receipt can become a JPG. Several receipts can become a PDF so they stay in order and are easier to submit as one document.
FAQ
Common questions
Is a PDF an image?
Not always. A PDF can contain selectable text, images, vector graphics, forms and scanned pages.
Can I edit a PDF like a Word document?
Only with the right editor and only if the PDF structure supports it. Many PDFs are designed for stable sharing rather than editing.
