EXIF & camera data
Make, model, lens, exposure settings, timestamps and orientation fields.
METADATADrop any image and PictureMatters builds a structured BlackBox report — camera metadata, GPS, provenance markers, entropy profile, byte signature and a cryptographic identity. Facts separated from interpretation, always.
Compare runs entirely in your browser: SHA-256 equality, size, dimensions, aspect and megapixel differences. Two files with matching SHA-256 are bit-for-bit identical; different hashes with identical pixels usually mean a re-save or re-encode.
No image handy? Generate a test specimen — a real PNG built in your browser, stamped with the metadata profile you pick, then run it through the analyzer to see a full report.
The specimen carries a tiny visible watermark; it is a synthetic demo image, not evidence of anything.
What a PictureMatters report reads inside an image file — from camera metadata to provenance signals. Every layer is documented, with its limits, in the methodology.
Make, model, lens, exposure settings, timestamps and orientation fields.
METADATAEmbedded coordinates with an approximate place name when available.
GPSWorkflow and publishing fields: creator tools, titles, credits, source declarations.
METADATAAI generator markers, IPTC digital-source declarations and C2PA Content Credentials presence.
PROVENANCEThe container mapped segment by segment — segments, chunks, comments, trailing data.
STRUCTUREByte-level unpredictability across the file, slice by slice.
ANALYSISJPEG quality estimate, progressive vs baseline, format-specific encoding details.
ENCODINGExact SHA-256 hash plus a perceptual fingerprint for near-duplicate comparison.
HASHESDimensions, megapixels, aspect ratio and a sampled color palette.
CHARACTERISTICSSoftware strings left by editors, exporters and platforms that touched the file.
SOFTWAREYour browser calculates dimensions, a SHA-256 fingerprint and an entropy preview before anything is sent.
Metadata, GPS, entropy, byte structure, palette, hashes and provenance markers are read.
A generator marker is not proof of AI. Missing metadata is not proof of anything either.
One page shows what was found, what it may mean, and where the evidence has limits.
Image analysis is only useful if you can trust how it's done. Three commitments shape every part of the product.
No account. No database. The original is deleted right after analysis and reports expire automatically. Not a promise — the way it's built.
READ THE SECURITY MODEL →Signals are labeled as signals. No fake certainty about AI detection or authenticity — the methodology documents what each layer can and cannot establish.
READ THE METHODOLOGY →Works on any device including iPhone HEIC, no install, no signup wall — and the knowledge behind it is free to read.
BROWSE THE GUIDES →Metadata can be removed. Markers can be edited. Entropy is statistical. Start with the plain-language guides — then read any report like an analyst.
The metadata standard your camera writes into every photo — and what it reveals.
What actually happens to metadata when images pass through messaging apps.
GPS metadata, who can read it, and how to stay in control.
Which signals honestly help — and which are folklore.
Short, honest answers about what image forensics can and cannot tell you.
No. The image is assembled temporarily for analysis and deleted immediately after the report is generated. The report itself expires automatically within 15 minutes.
No. Generator strings, C2PA markers and entropy are clues, not proof. Metadata can be removed or forged, so the report separates hard file facts from interpretation.
No. Screenshots, social apps and export tools routinely strip metadata. Absence of EXIF proves nothing about how the pixels were created.
Yes. HEIC and HEIF files are converted to JPG inside your browser before upload — on iPhone the conversion uses the browser's native decoder. Note that the conversion output is what gets analyzed, so the report reflects the converted JPG, not the original HEIC container.
It measures how unpredictable the file bytes are, slice by slice. Compressed photo data sits in a predictable range; appended payloads and embedded archives often stand out. Note that entropy alone cannot establish the presence of hidden data — unusual byte-pattern characteristics flag a region worth examining, nothing more.
C2PA is an industry standard for cryptographically signed provenance — a tamper-evident record of how a file was created and edited. PictureMatters detects supported markers but does not perform full cryptographic validation.
No account. No image library. The original file is used for analysis and then deleted automatically. We don't build a collection of your photos.
