    Image Metadata & Text-Chunk Inspector

    Pixel content and metadata are separate inputs. The inspector reports file structure and descriptive fields without sending the image to an external vision model.

    Research boundary: this page uses bounded, inert data and fixed safe examples. It never executes decoded content, requests secrets, calls third-party services, or performs actions against external systems.

    INPUT / CONTROL PLANE

    Build or inspect one controlled artifact.

    Idle
    Maximum 4 MB. No remote processing.

    Inputs remain on this host. Text operations are size-limited; uploaded files are processed from PHP’s temporary upload and are not retained by the application.

    OUTPUT / MACHINE VIEWS

    Compare evidence, not impressions.

    Run an analysis to populate the machine views.

    The response will separate summary metrics, representation views, findings, tables, and any generated safe fixture.

    Interpretation framework

    The same artifact can produce several valid observations.

    01

    Human view

    What a person naturally reads, sees, or hears.

    02

    Structural view

    What a parser, DOM, container reader, or metadata extractor exposes.

    03

    Decoder view

    What becomes meaningful only with a rule, key, tokenizer, model, or tool.

    04

    Defensive view

    What normalization, rendering, OCR, canonicalization, or policy changes.

    What this result can establish

    Interpret the receiver and transformation explicitly.

    Pixel content and metadata are separate inputs. The inspector reports file structure and descriptive fields without sending the image to an external vision model.

    Machine-decodable is receiver-relative. Record the parser, preprocessing, codebook, tokenizer, key, model, and transformation path before generalizing from one result.

    Limitations

    What this page does not prove

    The dependency-free inspector focuses on PNG tEXt/zTXt/iTXt and common JPEG EXIF. It is not a substitute for a full EXIF/IPTC/XMP suite.
