Inspect
Image inspector.
See what an image file really is: its true format, stored and displayed size, colour profile, transparency, animation and metadata, with the source of every value.
Values are read from the file's own bytes or measured by decoding it. Anything the file does not store is marked unknown.

What this means
When it helps
Why a file is rejected or looks wrong
Upload forms often check the file name and type. Images can also look sideways, washed out or broken in some apps because of an orientation tag, a wide-gamut colour profile, CMYK colours or a damaged file. The report points out these cases in plain language.

FAQ
Image inspection questions.
How can I tell an image's real format?
Every format starts with its own signature bytes, so the inspector reads the file's contents instead of trusting its name. If a file is named .png but contains JPEG data, the report says so and explains what that can affect.
Why can the stored size differ from the displayed size?
Phones often save photos sideways and add an orientation tag that tells apps to turn them. The stored size is what is in the file; the displayed size is what this browser shows after applying the tag. Apps that ignore the tag show the photo sideways.
Does a PNG with an alpha channel have transparent pixels?
Not necessarily. An alpha channel only means the file can store transparency. The inspector decodes the picture and counts the pixels that are actually transparent. Images up to 24 megapixels are counted exactly; larger ones are counted on an evenly sampled copy, and the report says when it is an estimate.
What do the source labels mean?
File bytes are read from the image's own structure. Decoded values are measured by decoding the picture in your browser. Metadata comes from fields such as EXIF, which any app can edit. File info is what your device reports about the file, such as its name. Unknown means the file does not store it or it cannot be detected reliably.
Is DPI the same as image quality?
No. DPI only says how large the image should print. A 3000 × 2000 pixel image has the same pixels at 72 or 300 DPI. Many images store no DPI at all, and the report says so instead of guessing.
Which formats can it inspect?
JPEG, PNG and animated PNG, WebP, GIF, HEIC and HEIF, AVIF, TIFF and BMP, up to 100 MB. Byte-level facts are read for all of them. Decoded values need a browser that can display the format: most browsers other than Safari cannot display HEIC, so for those files the report uses the stored values.
Can I save or share the report?
Yes. Copy it as text or download it as TXT or JSON. The report includes the file name and technical facts, and lists metadata such as location by type only, not by value.
Is my image uploaded?
No. The file is read in your browser on your device and is not sent anywhere. Nothing about the image is included in analytics.
