Screenshot Redactor
To redact a screenshot, cover each sensitive detail with an opaque box before sharing it. Solid black is the safest choice: blurring or pixelating small text can sometimes be reversed, while a filled box leaves nothing of the original pixels to recover.
How to redact a screenshot
Paste the screenshot
Press Cmd+V or Ctrl+V on the page, drop the image onto the box, or click to browse for a PNG, JPG, WebP, or HEIC file.
Check what was covered
Emails, phone numbers, card numbers, keys, tokens, @usernames, profile links, IP addresses, and faces are boxed automatically and listed under the image.
Fix anything it missed
Drag over any area to cover it, click a box or untick its row to uncover it, and switch a whole category off with its pill.
Download or copy
Download the redacted image in the same format you added, or copy it straight to your clipboard to paste into a chat or ticket.
Why use this tool
Finds the usual leaks
Email addresses, phone and card numbers, IBANs, API keys, access tokens, random-looking secrets, @usernames, profile links, and IP addresses are read off the image and boxed.
Faces and tiny avatars
Faces are found too, including the small round profile photos in app headers and chat lists, and covered with an oval.
Paste first
Built around the clipboard: take a screenshot, press Cmd+V or Ctrl+V on the page, and the result is ready to copy back out.
Boxes and list stay in sync
Every cover appears on the image and as a row with a masked preview. Untick a row or click its box to uncover it; drag to add your own.
Black, blur, or pixelate
Solid black is the default. Blur and pixelate are coarse enough that the text is gone, and the download matches the preview exactly.
Nothing leaves your browser
The screenshot is read and redacted on your device. Nothing is uploaded, and the download carries no hidden metadata.
About this tool
Screenshots leak more than people notice: the email in an account menu, a phone number in a settings page, an API key in a terminal, a teammate's face in a call. This tool reads the text in a screenshot, checks it against the same detectors used by the secrets scrubber, finds faces down to small profile avatars, and covers every match before you share it. It runs automatically the moment you paste or drop an image.
Detection reads English text and works best on crisp screenshots at their original size. It can miss text that is very small, low contrast, rotated, or set in a decorative font, and it does not recognise names, street addresses, or dates of birth, so treat the result as a first pass and look over the image before you send it. Dragging over anything it missed adds a box in one move. If you want the text itself rather than a cleaned image, image to text pulls it out instead.
Black boxes are the default because they are final: once the pixels are filled, nothing of the original remains in the file. Blur and pixelate are there for when a softer look matters, and both are applied coarsely enough to destroy the text rather than smudge it. For softening a whole photo rather than specific areas, use blur image. The download keeps the format you added (HEIC becomes JPG) and is re-encoded from scratch, so it carries no camera or location data.
Frequently asked questions
- How does it find sensitive information in a screenshot?
- It reads the text in the image, line by line, and checks each line for patterns such as email addresses, phone and card numbers, IBANs, API keys and tokens, @usernames, profile links, and IP addresses. Separately, it looks for faces, including small avatars. Every match gets a box on the image and a row in the list below it.
- Is my screenshot uploaded anywhere?
- No. Reading the text, finding faces, and drawing the boxes all happen in your browser. The first time you use it, the text reader and face finder download (about 30 MB together) and are then kept by your browser; the screenshot itself never leaves your device.
- Can it miss things?
- Yes. Small, faint, rotated, or stylised text may not be read, and some details have no pattern to match: names, street addresses, and dates of birth are not detected. Always look over the result before sharing, and drag over anything that still shows.
- Why is black the default instead of blur?
- Blurred or pixelated text can sometimes be reversed, especially short strings like numbers, by guessing candidates and comparing how they would look blurred. A solid black box leaves nothing to work with. The blur and pixelate options here are deliberately coarse, but black is the safe choice for text.
- What files can I use?
- PNG, JPG, WebP, and HEIC, one screenshot at a time. Pasting from the clipboard works anywhere on the page. The download is saved in the same format you added, except HEIC, which is saved as JPG. A pasted screenshot is saved as PNG.
- Is there a size limit?
- Very large images are scaled down to fit what a browser can safely draw, and the page says so when that happens. Typical screenshots, including full-page and 2x or 3x retina captures, are kept at full resolution.
