MaskBeforeShare

Document privacy

Redact a document photo before sending it.

Photos of contracts, letters, forms and receipts often include more information than the recipient needs. Cover irrelevant private fields, export fresh pixels and inspect the final copy.

Sensitive details masked locally before an image is shared.
Free. No signup. No image upload.

The image is processed in your browser. Review every mask, export fresh pixels, and share the cleaned copy instead of the original.

01

Define the purpose

List the facts the recipient needs so the redaction does not remove necessary context.

02

Black out private fields

Cover names, signatures, references, addresses, codes and unrelated text with opaque masks.

03

Flatten and reopen

Export a new PNG and confirm the hidden content is absent from the final pixels.

Before sharing

A document photo can leak information outside the page.

The desk, screen, envelope, filename and nearby paperwork can all expose additional data.

Is blur safe for document text?

Opaque blackout is safer for confidential text because weak blur may remain readable.

Can hidden text reappear after export?

The PNG export contains flattened pixels, but you should reopen it and inspect every region before sending.

Are document photos uploaded?

No. Supported image editing happens locally in your browser.
