Quick Answer
PDF, JPG, and PNG solve different problems. Use PDF when layout and pages matter, JPG for compressed photos, and PNG for screenshots, transparency, and crisp graphics.
Step-by-Step
- Use PDF for documents, forms, contracts, reports, invoices, resumes, and multi-page files.
- Use JPG for photos or image-heavy files where smaller file size matters more than perfect sharpness.
- Use PNG for screenshots, logos, transparent images, UI captures, and graphics with sharp edges.
- Convert PDF pages to JPG or PNG when you need image previews, thumbnails, or upload-friendly page images.
- Convert JPG or PNG to PDF when you need one shareable document or a printable attachment.
