BeforeUpload Redact: Private Screenshot Redaction Tool

Meet BeforeUpload Redact, a browser-based screenshot redaction tool that helps you cover sensitive text before an image leaves your device.

Screenshots are easy to share, which is exactly why they are easy to overshare.

A product bug, a payment screen, a customer conversation, an internal dashboard, or a support ticket can all contain details that should not travel with the image. An email address in the corner. A phone number in a sidebar. A card number in a receipt. An API key sitting in a settings panel. These are small details, but once a screenshot is uploaded, pasted into chat, or sent to another team, they can become permanent.

BeforeUpload Redact is built for that moment before you share.

Review the screenshot, cover what matters, and export a redacted copy without uploading the original image for analysis.

What BeforeUpload Redact Does

BeforeUpload Redact helps you find sensitive text in screenshots and cover it with solid black redaction boxes.

It is designed for common everyday images:

  • JPG screenshots
  • PNG screenshots
  • WebP images

You can add an image in the way that fits your workflow:

  • Drop an image into the page
  • Choose a file from your device
  • Paste an image from your clipboard

After the image is added, BeforeUpload reads the visible text it can detect, looks for sensitive values, and shows suggested redactions directly on the screenshot.

What It Looks For

BeforeUpload Redact is focused on the kinds of details people often miss when sharing a screenshot.

It can suggest redactions for:

  • Email addresses
  • Phone numbers
  • IBANs
  • VAT numbers
  • Italian tax codes
  • National ID numbers, including US SSNs, Canadian SINs, Brazilian CPFs, Spanish national IDs, and French social security numbers
  • Payment card numbers
  • API keys, tokens, private keys, database credential URLs, and other secret-like values

The tool groups findings into plain categories such as personal information and secrets, then shows a masked preview of each item so you can understand what was found without exposing the full value again.

Review Before You Export

BeforeUpload Redact does not force an all-or-nothing result.

Every suggested redaction is selected by default, but you stay in control:

  • Keep a suggested redaction selected if the text should be hidden
  • Uncheck it if the value is safe to leave visible
  • Preview the black boxes on top of the screenshot before exporting
  • Start over with a new image when needed

When you export, BeforeUpload creates a new PNG file with the selected areas covered in black. The download uses the original file name with `.redacted.png` added, making it easier to tell the safe copy apart from the original.

Private By Design

BeforeUpload Redact runs the review in your browser. The image is not uploaded to BeforeUpload for analysis.

That matters because redaction is often needed precisely when the screenshot contains something private. The safer workflow is simple:

  • Open the redaction tool
  • Add the screenshot
  • Review the suggested boxes
  • Export a redacted copy
  • Share the redacted copy instead of the original

The exported PNG is also cleaned of extra PNG metadata, so the file you share is focused on the visible image content and the redactions you chose.

Built For Real Sharing Workflows

BeforeUpload Redact is useful before sending screenshots to:

  • AI tools
  • Support desks
  • Bug trackers
  • Customer conversations
  • Vendor portals
  • Shared team channels
  • Public documentation
  • Social posts
  • Client updates

It is especially useful when the screenshot came from an account page, admin panel, payment system, analytics dashboard, developer console, email thread, CRM, help desk, or any other screen where private details can sit next to the thing you actually meant to show.

Language Support For Image Text

Screenshots are not always in English, so BeforeUpload Redact includes text-reading language choices for:

  • English
  • Italian
  • French
  • Spanish

Choosing the closest language helps the tool read the text in the image more accurately before it suggests redactions.

A Helpful Check, Not A Guarantee

BeforeUpload Redact is a practical guardrail, not a promise that every sensitive detail has been found.

Image text can be hard to read when it is tiny, blurry, angled, handwritten, cropped, low contrast, or hidden inside unusual graphics. Always give important screenshots a final human review before sharing them, especially if they involve legal, financial, medical, customer, employee, or security information.

The goal is simple: make the common mistakes easier to catch before they leave your device.
