Document Format Comparison

PDF vs JPG — Document vs Image

PDF and JPG serve different purposes. PDF is for documents — multi-page, layout-preserving, with text, tables, and images. JPG is for individual photographs — compressed images optimized for sharing. Knowing which to use for a given content type is fundamental.

Quick Verdict

Use PDF when…

Use PDF for documents — reports, forms, contracts, scanned multi-page material, or anything with text and layout that should remain consistent.

Use JPG when…

Use JPG for individual photos — what your camera captures, what you share on social media, what you embed in a website. JPG is for images, not documents.

Frequently asked questions

Should I convert a multi-page document scan to PDF or JPG?

PDF — every time. PDFs handle multiple pages elegantly; JPG forces you into separate files (page1.jpg, page2.jpg) which lose document structure. PDF also preserves any text data for searching.

How do I convert JPG to PDF?

Online: drag-drop tools. macOS: Quick Action 'Create PDF' in Finder. Windows: Print → Microsoft Print to PDF. Command line: `convert input.jpg output.pdf` (ImageMagick) or `img2pdf input.jpg -o output.pdf`.
