Post-export verification checklist
Most privacy misses happen in the final 10%: compressed previews, reflected details, or crop variants. Treat verification as part of the workflow, not an optional step.
- Check thumbnail and compressed preview versions, not just the full file.
- Run one final pass for secondary identifiers (badges, street numbers, documents).
- Open the final upload in full-screen and confirm identifiers are unreadable.
