Why blur text in screenshots and images?

Screenshots often capture more than you meant to share: email addresses, phone numbers, order IDs, API keys, balances or other people's messages. Blurring or pixelating that text before you post it in a support ticket, on social media or in documentation keeps it private.

This page is set up for text. It starts with a strong pixelate effect, which hides text more reliably than a light blur, and the rectangle tool matches lines of text. Paste a screenshot straight from the clipboard, redact it, then copy the result back.

How to blur text in an image online

  1. 1

    Open your image

    Choose Open image, drop a file on the editor or paste a screenshot with Ctrl/⌘ + V. JPG, PNG, WebP, GIF, BMP and AVIF are supported.

  2. 2

    Choose the effect

    Pixelate at a high setting is selected because it hides text reliably. Switch to Solid box for passwords and card numbers, or Blur for a softer look.

  3. 3

    Draw over the areas

    Drag a rectangle or ellipse, or paint with the brush. Add as many areas as you need. Click an area to change or delete it.

  4. 4

    Check and download

    Press and hold “Hold to see original” to compare, then download as PNG, JPG or WebP at full resolution, or copy the result to the clipboard.

Benefits of blurring images in your browser

Private by design
Your photo is decoded, edited and exported locally. It is never uploaded, so screenshots of bank statements or ID cards stay on your device.
Precise, flexible selections
Draw rectangles for text, ellipses for faces and brush strokes for irregular shapes. Each area keeps its own effect and strength.
Full-resolution output
Export at the original size as PNG, JPG or WebP, with quality control for lossy formats. There is no watermark.
Fast on phones and laptops
Effects are GPU-accelerated canvas filters. Nothing needs to be installed, and it works with touch.

A fast screenshot redaction workflow

  • Take a screenshot (Windows: Win + Shift + S; Mac: ⌘ + Shift + 4 or ⌘ + Ctrl + Shift + 4 to copy it).
  • Click on this page and press Ctrl/⌘ + V. The screenshot opens instantly.
  • Drag a rectangle over each line of sensitive text. Areas can overlap.
  • Choose Copy to put the redacted PNG on your clipboard, then paste it into Slack, email, a ticket or a document.

Common uses

Screenshots for support tickets
Hide email addresses, API keys, order numbers and customer names before you post a screenshot.
Social media and marketplaces
Blur faces of bystanders, children or house numbers before you publish a photo or listing.
Documents and IDs
Redact passport numbers, dates of birth and signatures in photos of documents you need to share.
Vehicles and dashcam footage
Pixelate licence plates in car photos, accident reports and street scenes.
Portraits and product shots
Use Outside shapes mode to blur a busy background and keep the subject in focus.
Spoilers and puzzles
Pixelate an answer or a spoiler so people can reveal it later by opening the original.

How to hide sensitive information safely

Light blur and small pixel blocks can sometimes be reversed or guessed, especially for short, predictable text such as card numbers, dates and licence plates. Research has shown that low-strength mosaics can be matched against candidate text.

  • For passwords, account numbers, addresses and ID numbers, use Solid box. It replaces the pixels completely.
  • If you prefer a softer look, use Pixelate with a pixel size of 60 or more, so each block covers several characters.
  • Cover the whole value, including the edges of the characters. Partial redaction can still reveal the number of digits.
  • Check the downloaded file, not just the preview, before you share it. This tool saves a new image, so the original pixels and EXIF metadata are not included.

How this tool compares with other online blur tools

We tested the image blur and pixelate tools that rank on Google's first page. Most are good at one job: blurring a whole photo, pixelating a rectangle or selling a larger editor. Several upload your photo to a server for processing. This tool puts the privacy-focused features in one place.

5 frequently asked questions about blurring text in images

Can blurred text be read again?

Light blur on short, predictable text can sometimes be reconstructed. That's why this page defaults to strong pixelation. For passwords, keys and card numbers, use Solid box, which removes the text completely.

Can I paste a screenshot directly?

Yes. Copy a screenshot to your clipboard, click on this page and press Ctrl + V (⌘ + V on a Mac). The image opens in the editor without saving a file first.

How do I hide several lines of text?

Drag one rectangle per line or one large rectangle over the whole block. You can also use the brush to follow text that isn't in a straight line.

Is my screenshot uploaded anywhere?

No. The screenshot is processed entirely by your browser, and nothing is sent to our servers. That makes it suitable for internal dashboards, bank screens and private chats.

Which format should I save a screenshot in?

PNG keeps text and UI edges crisp and is lossless, so it is the default for screenshots. Use JPG or WebP for photos, where smaller files matter more.
