MetaRinse guide
How to verify image metadata was removed
Compare the original and cleaned file, re-inspect the exact download, and use a second trusted inspector for sensitive sharing.
Verification is a process
Image metadata verification means checking the actual output file rather than trusting an encode button or a smaller file size. Record what the original contains, clean it, inspect the downloaded result, and compare the categories and visible image properties.
A successful encode is not enough. MetaRinse parses the output Blob with the same configured metadata reader and offers a download only when no readable private or descriptive fields are detected. That statement is intentionally narrower than “all traces removed.”
Printable verification checklist
- Keep the original in a separate folder.
- Inspect and record the original categories.
- Clean the image and wait for “Cleaned and verified.”
- Download the output; do not inspect only the browser preview.
- Check format, displayed orientation, width, height, transparency, and visual composition.
- Inspect the downloaded output with the operating system.
- For sensitive use, check with a second trusted local tool.
- Review visible information, filename, sharing link, and permissions.
Compare categories, not just counts
| Check | Original | Cleaned |
|---|---|---|
| Location | Coordinates visible | Not detected |
| Device serial | Masked until revealed | Not detected |
| Creator/comment | Readable text | Not detected |
| Technical dimensions | Width and height | Preserved |
| Visible pixels | Reference composition | Compare visually |
One verification record, end to end
| Checkpoint | Recorded result |
|---|---|
| Original JPEG scan | 21 readable fields; 14 private or descriptive |
| Original sensitive categories | 7 location, 4 device, 1 date/time, 1 description, 1 software |
| Cleaned Blob scan | 0 private or descriptive fields |
| Downloaded-file scan | 0 private or descriptive fields |
| Decoded output | 32 × 24 JPEG; displayed orientation and composition checked |

This evidence supports the narrower “not detected by the configured scanner” statement; it does not support a claim of anonymity.
Understand the wording
“No readable metadata detected” means the scanner did not find a supported private or descriptive field. Unknown vendor blocks, file-system timestamps outside the file, platform account records, backups, and visible details are different layers.
If verification fails
MetaRinse withholds the generated file and shows a file-specific error. Retry once in the current browser, then try a smaller batch or another current supported browser. Do not share an output that the tool marked unverified.
