| Check | What to review | Why it matters |
|---|---|---|
| Input | Non-empty, positive values or a supported image | Prevents invalid dimensions and browser decoding errors. |
| Output | Dimensions, ratio, quality, and visual crop | Confirms the transform matches the intended placement. |
| Final preview | Current publishing or ads surface | Platform behavior can change after this tool is reviewed. |
Clear answers
Questions creators ask
Practical notes for a faster, more confident pre-publish check.
Is my file uploaded?
No. The file is decoded and processed by browser APIs on this device only.
What happens when I check an image?
The result is generated in temporary browser memory. Download it before leaving; the site does not save a copy.
Does it work on mobile?
Modern mobile browsers are supported, but very large images can exceed device memory. Use a desktop for unusually large creative.
Does this fetch my website URL?
No. The checker only inspects the image file you choose and makes no external request.
