Frequently asked questions
Is the aspect ratio preserved?
Yes. You set the maximum width and the height scales proportionally — images are never stretched or squashed.
What sizes do Instagram and other platforms need?
Instagram feed photos work best at 1080 px wide, X/Twitter at 1600 px, Facebook at 2048 px. One tap on a preset fills in the right number.
Are my images uploaded to a server?
No. Resizing runs entirely in your browser — nothing is uploaded and no account is needed.
