FAQ

Does resizing upload my image?

No. The first version runs in your browser and does not upload the image by default.

Can I keep the original aspect ratio?

The page keeps aspect ratio controls visible so you can resize by width, height, or preset.

Which formats are supported?

PNG, JPEG, and WebP are the first supported input formats.

Does resizing use credits?

No. Resizing runs locally in the browser and does not use credits.

Can I resize product photos for marketplaces?

Yes. Use presets or custom dimensions, then review the final crop against the channel requirements.

Should I resize before compressing?

Yes when the source dimensions are larger than the final channel needs; resizing first usually makes compression more effective.
