Screenshot Redactor

Permanently hide sensitive info. No uploads, no servers.

Professional Screenshot Redaction Online

Our Screenshot Redactor is a professional-grade, browser-based utility designed for individuals and teams who need to share visual information while protecting sensitive data. Whether it's obscuring PII (Personally Identifiable Information) in a customer support ticket, hiding account numbers in financial documents, or blurring faces for social media, our tool provides a fast and 100% private solution.

100% Local

Your images never touch our servers. All processing happens entirely within your browser's memory.

Permanent Masking

Redactions are burned into the pixels. Unlike PDF overlays, this data cannot be "uncovered" after export.

Multi-Mode Privacy

Choose between solid blocks for maximum security, or blur and pixelate for aesthetic masking.

Why Use a Local Redaction Tool?

Most online image editors require you to upload your files to their servers. This creates a massive security risk: you are literally sending your most sensitive screenshots to a third party. Our tool eliminates this risk by using WebAssembly and Canvas APIs to process your image locally.

  • No Account Required: Start redacting immediately without giving away your email.
  • Zero Metadata Leaks: We strip technical metadata by default when exporting the redacted raster.
  • Mobile Ready: Capture a sensitive screenshot on your phone and redact it instantly before sharing.
  • GDPR Compliant: Since no data is collected or stored, it's the safest choice for business compliance.

Best Practices for Secure Redaction

While Blur and Pixelate are great for maintaining the visual context of an image (like blurring a background or a person's face), they are theoretically reversible with advanced AI de-blurring tools.

For highly sensitive data—like credit card numbers, passwords, or medical records—we always recommend using the Solid Redaction mode (Black or White blocks).

Frequently Asked Questions

Q: Is this tool safe for sensitive data?

Yes. All image processing happens locally in your web browser. Your screenshots are never uploaded to any server, ensuring your sensitive information remains private.

Q: What is the difference between solid redaction and blur?

Solid redaction completely replaces the pixels with a solid color, making it impossible to recover the original content. Blur and pixelate visually mask the information, but solid redaction is the most secure method for highly sensitive data.

Q: Can I redact multiple areas at once?

Absolutely. You can draw as many redaction rectangles as needed to cover various parts of your screenshot, such as names, addresses, account numbers, and faces.

Q: Does the redaction work on mobile devices?

Yes, the tool is fully responsive and supports touch interactions, allowing you to redact screenshots directly on your smartphone or tablet.

Q: What file formats are supported?

You can upload and export images in JPG, PNG, and WebP formats. We recommend PNG for screenshots containing text to maintain clarity.

Q: Are the redactions permanent?

Yes. When you download the redacted image, the masked areas are burned into the image pixels. The original hidden data is not included in the exported file.

Q: Can I change the color of the solid redaction?

Yes, you can choose between black, white, or any custom color to match the background or design of your screenshot.

Q: Is there a file size limit?

We support images up to 25MB, which covers almost all high-resolution screenshots and professional photographs.

Q: Can I add labels to redacted areas?

Yes, you have the option to add a 'REDACTED' label to solid blocks to clearly indicate that information has been intentionally hidden.

Q: Does this tool remove EXIF metadata?

This tool focuses on visual redaction. For complete metadata removal, we recommend using our dedicated 'Remove EXIF Data' tool.

Q: Can I undo or redo my changes?

Yes, the editor includes full undo and redo history, so you can easily correct mistakes while editing.

Q: How do I ensure seamless pixelation?

You can adjust the pixel size slider to find the right balance between obscuring the data and maintaining the overall look of the image.
