Frequently asked questions

How does the tool decide what to crop?

It scales your image to fill the target dimensions completely, then crops evenly from the center, keeping the main subject in frame in most photos.

Can I add custom dimensions?

The tool currently covers the most common social media presets. For anything else, the Image Compressor and Upscaler tools can help prep your file first.

What format is the output?

All resized images download as JPG at high quality (92%), which is what every major platform expects.
