Photo privacy checklist (2026)
Sharing a JPEG is easy; knowing what else travels with it is harder. This page is a field checklist for creators, support teams, and anyone posting home or workplace photos. It pairs with our local tools — we disclose that affiliation up front.
Layer 1 — Metadata (EXIF / GPS)
Many phone cameras store GPS, device model, and timestamps. That can reveal a neighborhood, travel pattern, or device fleet. Before posting: run EXIF Strip (Canvas re-encode, no upload) and spot-check with any EXIF viewer when stakes are high.
- Social posts of kids / home exteriors → strip GPS by default.
- Bug reports with screenshots → strip device tags; crop passwords.
- Marketplace listings → avoid reflections that show street numbers (visible PII, next layer).
Layer 2 — Visible content
Metadata tools do not blur faces, badges, whiteboards, or notification banners. Ask: would I be OK if this pixel grid were searched and screenshotted? Crop aggressively; prefer text redaction for documents.
Layer 3 — Where pixels are processed
| Pattern | Risk | When OK |
|---|---|---|
| Local Canvas (wordok-class) | Low upload risk | IDs, medical-adjacent, home interiors |
| Upload-to-server converters | Depends on vendor & retention | Public stock-like images only |
| Unknown “free SEO tool” farms | High | Never for private media |

Layer 4 — Draft marks & ownership
Watermark drafts before sharing with contractors (Watermark). Tile mode resists casual crop-outs. How-to: 加水印教程.
Suggested workflow
- Shoot / export the smallest useful crop.
- Strip EXIF.
- Optional watermark for drafts.
- Compress to platform limits (target KB guide).
- Upload only to the destination you intend — not a chain of random converters.
FAQ
Does Canvas strip guarantee zero metadata?
It removes typical EXIF for common formats. Odd containers or side-car files need specialist review. Verify when compliance matters.
What about HEIC from iPhones?
Convert to JPEG/PNG/WEBP in a trusted local path first; then strip. Platform HEIC support varies.
