Why blur an image?
A blurred background makes the subject pop like a portrait-mode photo, a fully blurred image makes a soft backdrop for text and slides, and pixelation hides faces, license plates and private information before you share a picture.
JPG (also called JPEG) is the most widely used photo format. It uses lossy compression to keep files small and works everywhere, but it does not support transparency and loses a little quality every time it is re-saved.
PNG is a lossless format that keeps every pixel exactly and supports transparent backgrounds. It is ideal for logos, icons, screenshots and graphics, but photos saved as PNG are often very large.
WebP is a modern image format created by Google. It supports both lossy and lossless compression plus transparency, and typically produces files 25–35% smaller than JPG at the same visual quality. All modern browsers support it.

Frequently asked questions
How does the background blur work?
An AI model finds the main subject — a person, pet or product — keeps it sharp and blurs everything behind it. The model (about 220 MB) downloads once and is then cached.
Can I un-blur an image afterwards?
No. Blurring and pixelating permanently remove detail, which is what makes them safe for hiding private information. Keep your original if you might need it.
Is this blur image tool free?
Yes. It is completely free with no sign-up, no watermarks and no limits on the number of images.
Are my images uploaded to a server?
No. Your images are processed entirely inside your browser, so they never leave your device. That makes it private and very fast, even for large files.
Can I blur many images at once?
Yes. Drop or select as many images as you like. Each one is processed in turn, and you can download them one by one or all together as a ZIP file.
Does it work on iPhone, Android and Mac?
Yes. It runs in any modern browser on phones, tablets and computers. Nothing needs to be installed.
