Inspect the XMP packet actually stored in a WebP RIFF container. The viewer finds the dedicated XMP chunk, decodes a safety-bounded UTF-8 representation, reports common packet and RDF markers, and preserves the selected source unchanged for a reviewable metadata audit.
How to use XMP Viewer
- Select one or more genuine WebP files whose embedded descriptive or rights metadata needs review.
- Run the local inspection and read the packet, byte count, truncation status, and structural markers in the JSON preview.
- Compare important fields with the source-of-record system before copying, removing, or relying on the metadata.
What this tool is good at
When to use XMP Viewer
Investigate an embedded XMP packet from actual bytes
Inspect descriptive, rights, creator, and workflow properties before a migration or publication decision. Use the selected WebP container as evidence instead of trusting only a filename, a browser preview, a rounded file-size label, or an assumption about what an exporter usually writes.
Prepare a reviewable metadata handoff
Read packet bytes, marker presence, size, and truncation status together rather than assuming any XML-looking text is complete or standards-conformant. Keep the local report or focused derivative with the related privacy review, preservation record, color decision, publishing ticket, or engineering investigation so another person can repeat the check.
Inspect sensitive assets without an upload
Work with client media, personal photographs, research imagery, unreleased campaigns, and internal diagnostics in the current browser tab without creating a remote image-processing job.
How to choose the right settings
Define the decision before reading the result
Inspect descriptive, rights, creator, and workflow properties before a migration or publication decision. Decide whether the goal is identification, privacy, preservation, interoperability, print planning, or container debugging because the same stored field can have different consequences in each workflow.
Separate a stored claim from proven reality
Read packet bytes, marker presence, size, and truncation status together rather than assuming any XML-looking text is complete or standards-conformant. Metadata can be missing, stale, edited, malformed, application-specific, or inconsistent with pixels; verify important conclusions against the authoritative record and destination application.
Retain and verify the original
The viewer does not fully validate RDF, namespaces, controlled vocabularies, or application semantics, and absence of XMP does not mean other metadata is absent. Keep the original until the downloaded report or derivative has been reopened, compared, and accepted by the person responsible for publishing or preservation.
Practical workflow and output details
The browser locates the top-level XMP chunk and decodes at most 256 KiB of UTF-8 text into a structured JSON report without rewriting RIFF data. Processing uses bounds-checked RIFF and TIFF reads, typed arrays, local Blob output, and Canvas only when visible orientation must be normalized; selected image bytes are never posted for processing.
The viewer does not fully validate RDF, namespaces, controlled vocabularies, or application semantics, and absence of XMP does not mean other metadata is absent. Government and institutional research links are presented as supporting references for format terminology and risk context, not as endorsements of PicConverters or proof that one focused tool satisfies every policy.
Format behavior and limitations
The viewer reports packet text but does not validate every XMP namespace, schema rule, controlled vocabulary, or application-specific property.
Packets larger than 256 KiB are deliberately truncated in the report to bound memory and interface output; the source file remains untouched.

Frequently asked questions
Does the viewer alter XMP?
No. It creates a separate JSON report from local bytes and never rewrites the selected WebP.
Why can an XMP packet look technical?
XMP commonly serializes RDF/XML with namespaces and application-specific properties intended for metadata software.
Is missing XMP an error?
No. XMP is optional in WebP, and many valid files do not include it.
