Screenshot Redaction Tool
Black out sensitive areas of a screenshot before sharing it.
Sharing a screenshot for a bug report, a tutorial, or a support ticket often means also sharing whatever happens to be visible in it — an email address, an account number, a customer’s name, or an internal URL. Screenshot Redaction Tool lets you draw solid black boxes over exactly the parts you don’t want visible before you post or send the image.
Why Use This Tool
A redaction tool that uploads your unredacted screenshot to a server before letting you black anything out has already defeated the purpose — the sensitive information has been transmitted regardless of what you do next. Talzos redacts locally in the browser, so the unredacted image never travels anywhere; only the version with the black boxes already applied is ever saved or shared.
Common Use Cases
Common uses: posting a screenshot to a public forum or support thread while hiding an account number or email, sharing a bug report internally without exposing a customer’s personal details, redacting a chat screenshot before including it in documentation, or blacking out pricing or contract terms in a screenshot shared outside the company.
How It Works
- 1 Upload a screenshot.
- 2 Draw boxes over sensitive areas.
- 3 Click "Export redacted image".
- 4 Download the flattened copy.
Frequently Asked Questions
Can the redaction be removed by someone else after I share the image?
No. The black boxes are drawn permanently into the image pixels, not layered on top, so the hidden content cannot be recovered from the exported file.
Is my screenshot uploaded before I redact it?
No. Everything happens locally in your browser.
Can I redact multiple areas in one screenshot?
Yes. Draw as many redaction boxes as you need before downloading.
What image formats are supported?
Common screenshot formats such as PNG and JPG are supported.
