Metadata Diff & Comparison Engine
Inspect exactly what metadata was detected, stripped, and preserved between the original and cleaned media files.
No files added yet
Drag and drop images, videos, or audio files here, or click to browse.
How It Works
Processing location depends on the selected tool and mode. Browser-based tools process files locally; advanced image processing may send the selected file to the ZeroMeta processing endpoint. Files are not intended to be stored permanently.
Select Media
Upload any image, video, audio, or PDF file to compare before and after state.
Automated Diff Generation
Our engine parses original tags and computes the exact delta of removed metadata.
Inspect Visual & Binary Diffs
Use the interactive compare slider for images and inspect the structured field-by-field table.
Supported File Formats & Capabilities
ZeroMeta validates authentic file binary headers and signatures prior to processing.
| Format | Extension | Inspection / Stripping Scope | Technical Notes |
|---|---|---|---|
| Images (JPG, PNG, WebP) | .jpg, .png, .webp | Interactive pixel compare slider + EXIF / GPS / XMP diff | Confirms visual fidelity while verifying metadata destruction. |
| Audio & Video | .mp4, .mp3, .wav, .mov | Container header diff, tag removal audit | Audits track titles, encoders, artist tags. |
| PDF Documents | Document Info Dictionary & XMP metadata diff | Compares /Title, /Author, and modifying application. |
Privacy Considerations
- All comparison diff calculations run 100% in client-side memory.
- Nothing is uploaded or stored during comparison.
Technical Boundaries
- •Comparison diff evaluates header tag presence, not pixel steganography.
Frequently Asked Questions
How does the comparison verify that GPS is gone?
ZeroMeta inspects the raw output binary and confirms that GPS IFD markers, latitude, longitude, and timestamp tags are absent.
Does the slider change image quality?
No, the compare slider directly renders the original buffer on one half and the re-encoded clean buffer on the other so you can visually verify zero perceptible loss.
