What does image resizing do?

This tool is aimed at straightforward browser-local resizing: adjusting dimensions, changing the export format, and comparing the output before download. It is a good fit when you want privacy and speed more than a full editorial workflow.

Good use cases

Preparing screenshots for docs or issue trackers.
Shrinking images before attaching them to forms or messages.
Exporting a quick JPEG or WebP version from a larger PNG.

Where a heavier pipeline still wins

Batch processing many images at once.
Color-profile preservation and metadata management.
Advanced transforms such as cropping, rotation, or sharpening.
