Client-Side Image Redaction & Data Masking
When sharing debug screenshots, customer invoices, error logs, or software walkthroughs, accidentally exposing sensitive credentials (like Stripe API keys, database connection strings, passwords, or personal identity information) creates serious security risks.
Why 100% In-Browser Redaction Matters
- Zero Server Uploads: Most online image editors upload your screenshots to remote cloud servers for processing. This tool processes every pixel locally via the HTML5 Canvas API on your own device—your raw and redacted images never touch a server.
- Irreversible Pixel Transformation: Unlike PDF overlay boxes that can sometimes be removed by PDF readers, rasterized pixelation and blackout permanently overwrite the underlying pixel data in the exported bitmap, making extraction impossible.
- Flexible Masking Tools: Choose between rectangular box selection for structured tabular data/credentials, or freehand brush painting for irregular signatures and faces.
- Direct Clipboard Integration: Redact sensitive areas and paste directly into Slack, Jira, GitHub issues, or emails without cluttering your downloads folder.
