This tool offers three ways to blur. Blur whole image softens the entire picture with an adjustable radius, useful for backgrounds and placeholders. Pixelate whole image turns it into large blocks. Blur areas lets you drag rectangles over exactly the parts you want to hide, such as faces in a crowd, a car’s number plate, a house number, or names and email addresses in a screenshot.
You can add several areas, undo the last one, and switch between blur and pixelate with a strength slider. The result is saved at full resolution. Because the photo never leaves your browser, you can safely redact sensitive screenshots and documents without handing them to an online service.

Blur or pixelate: which hides better?
For hiding information, strong pixelation with large blocks is generally safer than a light blur. A weak blur on large text can sometimes still be guessed, especially on screenshots with known fonts. Turn the strength up until the text is completely unreadable, and make the box a little larger than the text itself.
For the most sensitive details, such as passwords, card numbers or ID numbers, cropping them out entirely is safer than any blur. Blur is best for faces, plates and backgrounds where you want to keep the rest of the scene.
When to blur before posting
Many people blur children’s faces, strangers in the background, vehicle plates, street numbers and delivery labels before sharing photos publicly. In screenshots, check for email addresses, phone numbers, order IDs and chat names. Taking ten seconds to blur them helps protect your privacy and that of others.
Frequently asked questions
How do I blur only part of a picture?
Choose Blur areas and drag a rectangle over the part you want to hide. You can draw as many rectangles as you need; each one is blurred or pixelated.
Can the blur be reversed?
Not from the saved file. The original pixels in the blurred areas are replaced, so they cannot be restored from the downloaded image. Use a high strength to make sure nothing can be guessed.
Does it work on phones?
Yes. You can drag areas with your finger on touch screens.
Is my image uploaded to blur it?
No. Blurring is done by your browser on your own device, which makes it safe for screenshots with private information.
