Why resize in the browser?
Uploading and downloading a photo just to shrink it is slow. Doing it in your browser is faster and the file never leaves your device.
The tool uses high-quality browser resampling to keep edges sharp. For Instagram and Stories, the presets export at the exact pixel sizes each platform expects.
