Common use cases

When to consider paid software

Use the free compressor for quick image-size checks. Use a dedicated image optimization plugin or CDN when you need automatic compression across a full website. Paid software may be better when you need batch automation, team permissions, audit trails, brand templates, cloud storage, advanced editing, compliance controls, or customer support.
