What it does
Inspect static JPEG, PNG and WebP headers and a bounded EXIF subset. Encoded dimensions and file properties are distinguished from capture time.
When to use it
Use this tool when its stated local workflow and limits match your task. Review the result before relying on it.
Steps
- Select a compatible local image.
- Choose Read metadata and review the format, dimensions and file properties.
- Inspect supported EXIF fields and the GPS warning before sharing the image.
Verifiable example
Input: A synthetic 80 × 60 JPEG with Make=ViBytes Tools Fixture and DateTimeOriginal=2024:01:02 03:04:05.
Expected result: image/jpeg, 80 × 60, literal make and EXIF date; file modification time appears separately.
Common mistakes
Renaming an SVG, animated image or corrupt file to .png does not make it valid. Choose a supported original file, then check dimensions and format.
Limitations
- Up to 5 MiB, 8 megapixels and 4096 px per side; EXIF up to 256 KiB and 128 entries per IFD. Only supported make, model, orientation and EXIF dates.
- No XMP/IPTC/MakerNote reading or metadata removal. Detecting a GPS directory does not verify coordinates; absence does not prove privacy. Dates do not certify authenticity.
Frequently asked questions
Is my input uploaded?
No. This workflow runs locally in the browser. Visiting the site still downloads software and public resources; inputs and results are not stored automatically.
Does this certify security or authenticity?
No. Read the stated scope and limitations. Browser memory, extensions and the operating system remain outside a guarantee of forensic erasure.
