FAQ

Will resizing reduce image quality?

Enlarging an image can soften it, since no new detail is created. Shrinking generally looks sharp.

Can I resize without keeping the aspect ratio?

Yes — uncheck "Keep aspect ratio" to set width and height independently.

What size should I use for Instagram or Facebook?

There's no preset button — just type the dimensions in directly. Common sizes: Instagram square post 1080×1080, Facebook cover photo 820×312, LinkedIn banner 1584×396.

Does this work on Mac, Windows, or my phone?

Yes — it runs in any modern browser on Mac, Windows, Chromebook, iPhone, or Android. No app or software to install.
