Blur or redact part of an image
Drag over anything you need to hide. Blur pixelates the area; Redact covers it with a solid block. Because the work happens in your browser, the unredacted original never leaves your device.
How to use the blur part of an image tool
- 1
Add your image
Drop a file, pick one from your device, or paste a screenshot with Ctrl+V (⌘+V on a Mac).

Download
Save the marked-up image as a PNG at the original resolution, ready to send or attach.
Pixelate or redact?
Pixelation keeps the image looking natural and works well for faces and backgrounds. For short, high-value text such as passwords, card or account numbers, use Redact: a solid block leaves nothing to reconstruct.
Is it permanent?
Yes, in the file you download. The hidden pixels are replaced before the PNG is created, so there is no layer to remove. Keep your original if you might need it later.
Frequently asked questions
Can someone un-blur the downloaded image?+
The original pixels are replaced in the downloaded file, so there is no hidden layer to remove. Pixelation of very short text can sometimes be guessed, so use Redact (a solid block) for passwords and numbers.
What’s the difference between Blur and Redact?+
Blur pixelates the area into large blocks. Redact fills it with a solid colour. Both are applied to the downloaded PNG.
Are my files uploaded anywhere?+
No. This tool runs entirely in your browser, so the file never leaves your device. Closing the tab discards it.
Which image formats can I open?+
PNG, JPEG, WebP, GIF, SVG, BMP and, in recent browsers, AVIF. For a GIF, only the first frame is used. The result is always saved as a PNG.
Does it reduce the image quality?+
No. Your marks are drawn onto a copy at the image’s full resolution, and PNG is lossless. Very large images (over about 16 megapixels) are scaled down so browsers can handle them.
Is it free? Do I need an account?+
Yes, it’s free and there’s no signup, watermark or daily limit. An account is only needed if you want teammates or clients to comment on the file in edits.io.
Need feedback, not just a file?
Send clients one review link and track every project to approval. Clients comment with a link, no account needed.
