How This Compares to Other Tools
Most free "EXIF cleaners" - however good - edit or delete known metadata fields out of the file that's already there. This tool decodes every image down to raw pixels and rebuilds the file from nothing, so the comparison below is really "field editing" vs. "full reconstruction," not a feature checklist. The right-hand columns reflect each project's own public claims as of this writing, not independent testing on our part - we link what we could verify inline.
| Capability | This tool | Tag-based browser cleaners (PrivMeta, MetaClean, etc.) |
ExifTool (CLI) |
Enterprise CDR (Votiro/OPSWAT-class) |
|---|---|---|---|---|
| Method | ✓Full pixel decode & re-encode | ✗Metadata field editing | ✗Metadata field editing | ✓Full reconstruction |
| Defeats polyglot / appended-payload files | ✓Structural, not detection-based | ✗Not their threat model | ✗Not their threat model | ✓Yes |
| Runs with zero upload (client-side/local) | ✓WASM in-browser | ✓Most of them | ✓Local binary | ✗Server/gateway product |
| Open source | ✓Yes | ~Some (PrivMeta, MAT2); not all | ✓Yes | ✗No |
| Decodes and displays actual field values (GPS, camera, etc.), not just "cleaned" | ✓Yes, with a map link for GPS | ~Rarely beyond a raw tag list | ✓Raw tag dump, technical | ✗Not their purpose |
| Flags embedded-thumbnail vs. main-image mismatch (tamper tell) | ✓Yes | ✗No | ✗No | ✗No |
| Detects C2PA/provenance manifests before stripping | ✓Yes | ~AI-focused tools only | ✓Tag-level | ~Varies |
| Steganography (pixel LSB) mitigation option | ✓Yes, opt-in | ✗No | ✗No | ~Varies by vendor |
| Forensic hints (ELA / copy-move) with explicit non-verdict caveat | ✓Yes | ✗No | ✗No | ~Rarely surfaced to end user |
| Decompression-bomb / resource-limit guard | ✓Yes, tested | ~Unknown / unverified | –N/A (reads only) | ✓Yes |
| Handles iPhone photos (HEIC/HEIF) | ✓Yes, decoded client-side via a WASM module | ~Some do, some don't - check before assuming | ✓Yes (with the right plugin) | ~Varies by vendor |
| Price | ✓Free, open source | ✓Free | ✓Free | ✗Enterprise licensing |
"Not their threat model" means exactly that - these are good tools for what they're built for (removing known metadata fields quickly). They're not incomplete versions of this one; they're solving a narrower problem on purpose. ~ marks "partial/varies," not "bad" - it's doing real work to avoid flattening honest nuance into a false yes/no.
