Image privacy mask

Drag a selection, move it or resize it using eight handles. Apply a solid mask for sensitive text. Mosaic may retain outlines or colour patterns and should not be treated as guaranteed anonymisation.

Useful for

• Hide names and avatars before sharing a conversation
• Cover private details on an order or receipt
• Mask signatures or account details in a document image

How to use it

1. Choose an image and drag a selection
2. Adjust the box and choose solid masking or mosaic
3. Apply each area, then download and inspect the new image

Singapore example: Sharing an order problem

Practise on a fictional order. Cover the name, phone, address, pickup code, QR code and order number, leaving the relevant product or error visible.

Apply every area and inspect corners, notifications and the filename. The tool does not certify removal of all metadata or prevent others from resharing.

Things to check

• Use solid masking for highly sensitive information
• Mosaic can preserve clues about the original
• Apply one area before creating another
• Review image edges and the downloaded file before sharing
