Image File Extension Mismatch
Check whether the filename extension matches the image format detected from the file contents, and create a correctly named local copy when the evidence is strong enough.
ARADURU checks file-side evidence in your browser first, then separates file problems from app or website problems.

An extension is a filename label, not a conversion
A file can be called .jpg, .png, .gif, or another extension while its internal image structure identifies something else. ARADURU checks the contents before recommending any rename-style fix.
The image opens only after renaming
A viewer may rely on the filename extension even when the internal image format is otherwise readable.
The real image format is different
A .jpg filename can contain PNG, GIF, WebP, BMP, TIFF, or another recognizable file structure.
Renaming does not convert the image
Changing the extension cannot transform pixels or image encoding. A safe rename is appropriate only when the contents already match the target format.
How ARADURU checks this image problem
Identify the image format from file contents instead of trusting the extension alone.
Compare common aliases such as .jpg/.jpeg and .tif/.tiff correctly.
Check the image structure before recommending a filename-only correction.
Offer a Safe Automatic Fix only when ARADURU can create an identically encoded copy with the correct extension.
How to interpret the match level
ARADURU found concrete image-format or structure evidence that can directly explain or strongly contribute to the selected problem.
ARADURU found relevant file-side evidence, but the same image problem can also have application, browser, rendering, or destination-specific causes.
The current image structural checks did not reveal an obvious match for this problem. Continue troubleshooting outside the file structure.
What this check cannot prove
A corrected filename does not convert, recompress, repair, or change the image contents. The destination application or website can still impose its own format, size, feature, or upload restrictions.
Common questions about this image problem
Does changing .jpg to .png convert the image?
No. Renaming only changes the filename. If the contents are actually PNG, a .png name can be appropriate; otherwise conversion requires an image application.
When does ARADURU offer a corrected copy?
Only when the detected file contents provide strong format evidence and the existing Safe Fix can change the filename without changing the file bytes.
What if the extension already matches?
Then an extension mismatch is not the obvious cause. If ARADURU finds a separate structure problem, address that issue instead.
