How to choose the right photo resolution
Resolution should match the final use. A camera original may be excellent for print or cropping but too heavy for a website page. A small thumbnail may load quickly but look soft if placed in a wide hero area. The best workflow is to keep a high-resolution master and create optimized copies for each publishing size.
For SEO and user experience, avoid serving more pixels than users can see. Resize images to realistic display dimensions, compress them with a suitable format, and use responsive image markup where possible.
