JPEG vs PNG: practical differences
JPEG and PNG serve different delivery goals. The right choice depends on compatibility requirements, compression budget, and pipeline speed.
In real teams, format choice should be policy-driven, with clear fallback behavior and consistent export presets.
When to choose JPEG
Choose JPEG for most product photos where file size and load speed matter most.
Validate with side-by-side preview and target-size constraints before applying policy to full catalogs.
When to choose PNG
Choose PNG for assets that need lossless treatment or specific transparency workflows.
For mixed ecosystems, define fallback output and avoid one-format assumptions across every channel.
- Use category-based format policy
- Measure real storefront impact
- Keep QA consistent
