Frequently asked questions
Shrinking an image loses very little visible quality. Enlarging it beyond its original size can look soft, and the tool warns you before that happens.
No. Every resize happens on your device using the browser's own canvas - nothing is sent to a server.
The preset chips cover the most common targets: a 1080x1080 square post, a 1080x1920 story, 1920x1080 for a video thumbnail or HD banner, and a 512x512 avatar.
Yes. Drop several images, set a size on the first one, and use "Apply this size to all images" to copy it across the rest - each keeps its own aspect ratio unless you turn that off.
