Using Image Forensics Studio

Image forensics uses multiple weak signals, not one definitive detector. ELA recompresses a normalized browser-rendered image to JPEG and displays the difference; this can reveal unusual residual patterns, but does not establish manipulation. PNG/WebP ELA is especially an exploratory JPEG conversion.

Fine-detail residual highlights rapid local luminance changes, including real edges and texture; it is not a sensor-noise measurement. Compression boundaries show discontinuities at fixed 8×8 tile edges. They are affected by real edges, resampling and image content; they are not a JPEG quantization decoder. File metadata can be missing, edited or fabricated.

Use Select area to draw a rectangular region for histogram and pixel-difference measurements. When a region is selected, its coordinates are recorded in the JSON report. The Align B action searches only for small x/y translations and may give misleading matches on flat or repetitive images. Pixel differences operate on decoded, browser color-managed display pixels. Different image dimensions are rejected unless you explicitly opt into scaling B to A, which adds resampling artifacts. Similarity uses a 64-bit difference hash, not an AI-authenticity detector.

Photos are processed only in this tab. Source images are not saved to localStorage or uploaded. Reports contain findings and hashes, but no original photos. Exported screenshots omit original EXIF/ICC metadata. Only JPEG, PNG and WebP are supported, up to 48 MB and 48 million pixels each; processing is downsampled to fit device memory.

Normal browser EXIF orientation and color conversion may change how decoded pixels compare. Preserve the original files when conducting forensic analysis. No forensic conclusion should rely solely on the outputs here.

Using Image Forensics Studio

Open a supported image, inspect metadata and select a region for closer analysis. Compare another photograph with supported translation alignment and review residual/ELA views in context. Export descriptive findings while retaining original files separately.

Compression residuals, ELA and similarity scores are investigative aids rather than proof of forgery, authenticity or AI generation. Alignment is a small translation search, not full registration. GPS is reported as presence rather than exposing suppressed coordinates. Browser decoding, metadata coverage and image/resource budgets limit results; interpretation needs independent context.

Workflow and output choices for Image Forensics Studio

Review supported image metadata, JPEG characteristics, selected-region histograms and residual views. Compare two images with bounded translation alignment and export descriptive findings.

Analysis output is an investigative aid, not an authenticity verdict. Metadata reports GPS presence without revealing suppressed coordinates; retain the original image files separately for context.

Example workflow

  1. Open a supported image and inspect the available metadata and JPEG details.
  2. Select a region for its histogram or compare another image using the supported small translation search.
  3. Review ELA or residual views alongside the originals and export notes without treating a visual difference as proof.

Authored example: Consider a fictional image saved once more at a different JPEG quality. Review the resulting residual view and write a neutral observation about where differences appear; this exercise does not establish manipulation.

Limits and handling: ELA, residuals, metadata and similarity are descriptive investigative aids; they do not prove authenticity, forgery or AI generation. Translation search is limited, browser decoding and metadata coverage vary, and coordinate values may be suppressed.

Image Forensics Studio questions

Can an ELA or residual view prove that an image was forged?

No. These are investigative aids that can reveal differences but cannot establish authenticity or forgery by themselves.

Does the metadata view disclose hidden GPS coordinates?

It reports GPS presence without exposing suppressed coordinates. Keep original files and independent context for any investigation.
