iMessage and WhatsApp screenshots are how people prove a conversation. They are also how a name, a phone number, a face in a circular avatar, and a one-time passcode leave the lock screen and land in a group chat, a Reddit post, or an HR ticket. The other person did not agree to that broadcast. Neither did anyone else in a group thread whose avatars sit in the header.
HideShot’s toolbar on this page is the live tool: Black Box, Blur, and Pixelate, with rectangle, oval, or lasso. Black Box is the mode for text. Blur and Pixelate are for faces when you only need casual cover. Draw locally, download a PNG, and share the export — not the original capture from Recents.
Guide
A chat screenshot is a photograph of someone else’s identity plus yours. iMessage puts a contact name and sometimes a phone number in the large header. WhatsApp repeats the name, a profile photo, and last-seen or group-member chrome. Bubbles contain the words you wanted to quote — and also emails, street addresses, “I’m at 14B,” and six-digit codes from a bank. Quoted replies reprint the name you already covered in the header. Status-bar banners can show a new incoming message from a third person while you capture.
This page is not a generic “redact any screenshot” tutorial and it is not Discord or Slack. Those apps have their own chrome. Consumer messengers leak through headers, avatars, and SMS-style numbers. Cover those first, then the bubbles.
What to cover on iMessage and WhatsApp — and which mode to use
Use Black Box for anything a reader could type into a search box: display names, phone numbers, emails, handles, message text you are not publishing, 2FA codes, and addresses. The safety tip on the toolbar is accurate: Blur and Pixelate may leave details visible. That is a property of those filters on sharp UI type, not a slogan.
Use Blur or Pixelate for profile photos and faces in video-bubble stills when the goal is to stop casual recognition in a story post. Do not use those modes as the only cover on a phone number. If you need the screenshot to still “look like a chat” for a tutorial, Pixelate a face and Black-Box the number. Two modes on one image is the usual honest combination.
Group threads need a second pass. Participant lists, “You added X,” typing indicators, and stacked avatars in the header all name people who are not in the two bubbles you meant to share. Cover them. A screenshot of a scam thread still includes the scammer’s number — that number is evidence, but it is also a live identifier if you post it publicly. Decide which audience is allowed to see it before you skip the box.
How to redact a chat screenshot in the tool above
- Capture the thread, then drop the PNG/JPEG onto this page or paste with Ctrl+V / Cmd+V. The file stays in this tab.
- Black-Box the header name and number. On iMessage, that is the top contact label. On WhatsApp, include the photo circle if a face is identifying.
- Walk every bubble, including quoted replies and link previews that reprint a name or a map address. See hide email addresses in screenshots if an @address sits in the thread.
- Cover handles and usernames the same way you cover legal names — hide username in a screenshot is the same job when the chat shows an @handle instead of a phone book name.
- Check the status bar, notification shade, and keyboard autocomplete. Download PNG. Zoom the export. If you can still read a digit through Blur, undo and Black-Box that region.
Realistic chat-screenshot scenarios
Posting a scam or harassment thread for a warning post. The public needs the pattern of the pitch, not the other person’s full number sitting in the header. Black-Box the number and the avatar. Leave the wording of the scam if that is the point of the post.
Sending a screenshot to a roommate, parent, or HR. Private audiences still forward. Cover the third parties in a group chat who are not part of the dispute. Cover 2FA codes immediately — those expire, but the screenshot does not.
A gaming or hobby group that lives in WhatsApp rather than Discord. Gamertags, real names, and voice-note waveforms sit next to each other. Treat the header like an identity card. Pixelate faces if you want the meme to survive; Black-Box the phone number always.
Common mistakes on messenger screenshots
Covering bubbles and leaving the huge iMessage name untouched. The header is the first thing a reader sees.
Using Blur on a phone number because it “looks nicer.” Zoomed Blur is still a number. Black Box it.
Cropping the header in Photos and calling the job done. Cropping does not cover quoted names inside bubbles or a notification that slid down during the capture.
Exporting, then attaching the original from the camera roll because the PNG “looked softer.” Share the HideShot download only.
