What this tool does
Check whether your browser can decode an image and read its pixel dimensions. No repair or malware-free claim.
How to use
Choose a supported image and process. Read the decode status, width, height and byte size; download the text report if needed.
Limitations
25 MB and 40 megapixels. JPG, PNG, WebP, GIF, AVIF and BMP extensions are accepted; actual decoding support depends on the browser. A successful decode is not a full file-integrity or malware check. Failed decoding may mean unsupported format rather than corruption. No repair, recovery or animation-frame validation.
FAQ
Are files or text uploaded?
No. Processing happens locally in your browser.
Should I review the output?
Yes. Compare it with the original using the stated limitations before use.
Does it work on mobile?
Modern browsers are supported; format support and available memory depend on your device.
