Are images uploaded to the server?

No. Compression, resizing, and format conversion all run locally in your browser.

Should I choose JPG, PNG, or WebP?

Use JPG for most marketplace uploads, WebP for faster web loading, and PNG when transparency matters.

Can I keep editing product images after compression?

Yes. After basic optimization, you can continue in SKUCanvas to create main images, lifestyle scenes, and detail-page assets.
