Start with the question you need answered

A percentage share, a percentage change, and a discount use related arithmetic but answer different questions. Likewise, cropping, resizing, and choosing an output format solve different image problems. Each tool page explains the choice with worked examples, so you can match the utility to the task.

Tool inputs are processed locally, without an application account or file-upload service. Clipboard behavior, browser file support, and hosting access can still affect your experience. Read the FAQ for practical questions or browse the full page directory.
