How to Blur Faces in School Photos (Online, No Download)

Published October 22, 2025 · 6-minute read

Schools capture unforgettable moments—classroom projects, field trips, big wins on the court. But sharing those photos online can expose students’ identities. BlurFaces lets you protect kids’ privacy without uploading originals to any server.

Why it matters

Many privacy frameworks, from FERPA guidance in the United States to GDPR across Europe, urge parents and educators to avoid publishing identifiable student imagery. Even closed Facebook groups or classroom apps can leak. Applying a face blur removes that risk while keeping the memory intact.

BlurFaces runs entirely in your browser

• No uploads: The original never leaves your device; face detection and blurring happen locally.
• Smart detection: Automatic face boxes with manual add/remove tools for teachers using props or costumes.
• Fine control: Adjust padding and blur strength so the result looks natural but safe.

Step-by-step workflow

1. Open BlurFaces and drag a class photo into the drop zone.
2. Review the detected faces. Toggle any boxes you want to keep visible, or tap “Add mask” to draw over nametags and chalkboards.
3. Adjust the padding slider to cover hairlines or hats.
4. Pick a blur strength—12px is a safe default, while 20–24px hides faces even in close-ups.
5. Export a blurred copy. You can grab the free watermarked version or upgrade for HD and watermark-free downloads.

Share responsibly

Need to pass the photo to another teacher or administrator? Create a 24-hour ShareLink that only includes the blurred version. Set a reminder to delete classroom copies once the project ends.

Pro tip: batch your blur sessions

Upload multiple shots from the same event. BlurFaces keeps face selections consistent, so you can export a whole album with the same settings.
