Processing method

Image output depends on source dimensions, file format, compression quality, and transparency. Photos, logos, and text-heavy graphics can react differently to the same setting, so review both pixel dimensions and visible quality.

How files and inputs are handled

Core processing runs in the current browser whenever possible. OneClickTool does not store original files or tool inputs on its own server. Review the preview and output values before downloading or submitting an important result.
