Image Format Detector

How to use Image Format Detector

1. Select your input

Choose a JPG, PNG or WebP image from your device using the file button or supported drop area. The standard file picker accepts browser-readable images up to 25 MB; decoding support depends on the file and browser.

2. Understand the settings

Detected Format shows MIME type, interpreted format, filename extension and size.

3. Process and review

Choose the file, compare type and extension, and use Image Converter if a different output is required.

4. Save your result

The inspection itself does not need a new image download. Read the displayed values; open a linked editing tool when you actually need to change the image.

Supported formats

Input: a browser-readable image, normally JPG, PNG or WebP, up to 25 MB. The result is displayed file and decoded-image information rather than a converted image.

When to use this tool

Inspect the image type reported by the browser and related file information. Use it as a practical starting check before selecting a conversion.

What to check in the result

A filename extension can be wrong, and a browser MIME value is not a full file-security scan. Confirm specialist formats with an appropriate parser.

Continue with Image Converter when that step fits your workflow.

A practical example

Check a file renamed .jpg when its decoded MIME type still indicates PNG.

Capabilities and limitations

This is browser-level type reporting, not a forensic file-signature or corruption validator.

Troubleshooting

If the browser identifies the file differently from its extension, use that discrepancy as a reason to inspect the source. This is not a complete binary-format validator.

Processing and privacy

Image pixels are processed on your device. Loading the website and processing assets still uses a network connection, and hosting may receive normal request information. Keep original files backed up.
