What is PDF Format and Why It’s Essential
PDF explained: why it is universal, how it preserves layout, and when to use it over images for sharing.
A portable, standardized format
PDF is an ISO‑standardized format designed to preserve layout, fonts, and graphics so documents render consistently across devices.
Core benefits
What you see is what others see — PDFs embed fonts, define page sizes, and lock layout. This is ideal for final reports, forms, and print‑ready files.
When to use PDF vs images
Choose PDF when you need multi‑page documents, reliable printing, or a single file to share. Use images when editing individual photos.
Archiving and PDF/A
PDF/A is a subset of PDF for long‑term archiving, with rules to ensure self‑containment (embedded fonts, no external dependencies).

FAQs
What is PDF/A?
An ISO standard (19005) for archivable PDFs that are self‑contained and suitable for long‑term preservation.
Why does my PDF look different on another device?
If fonts are not embedded or the app is non‑compliant, rendering may vary. Exporting correctly and viewing in compliant readers reduces issues.
