FAQ
Are images uploaded to a server?
No. This checker uses browser APIs to inspect the selected file locally.
Is 800 x 800 always enough?
It is a useful minimum for many workflows, but larger square images can be better when a marketplace or store supports zoom.
Which formats should I use?
JPG, PNG, and WebP are common web formats. JPG is often efficient for photos, PNG can preserve clean graphics, and WebP can reduce file weight.
