Common use cases

When to consider paid software

Use this tool for one-off resizing. Use design software when you need cropping guides, brand templates, or batch exports. 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.
