Resize workflow by use-case

Use display-first sizing: choose dimensions based on where the image will be shown, then export once. This avoids repeated re-encoding and keeps visual quality more predictable across web, e-commerce, and social feeds.

When a fixed ratio is required, decide between crop and pad based on content safety. Crop fills the frame but may cut important edges. Pad preserves all pixels but adds background area, which is often better for catalogs and compliance images.

What long-edge value is a good default?

For many web uploads, 1280-1920px long edge is a practical start. Use larger values only when the destination supports zoom or print.

How is resize quality handled?

Resize uses a high-quality server default tuned for photo and web graphics. The goal is to keep the common path simple and predictable.

Can resize and compression be combined?

Yes. Resize first, then compress. This usually produces smaller files with fewer artifacts than compression-only workflows.
