Benefits
Private by design

Instant results
Blur Image finishes most jobs in under a second because the work happens on your own hardware.
No signup, no limits
Use Blur Image as many times as you want. Blur Image asks for no account, adds no watermark and keeps no paid tier gating the output.
Works offline
Once the page has loaded, Blur Image keeps working without a connection, which helps on flights and locked-down networks.
Who it is for

How it works

Frequently asked questions
Is Blur Image free to use?
Yes. Blur Image is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Blur Image upload your image to a server?
No. Blur Image processes your image inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Blur Image.
Do I need to install anything to use Blur Image?
No installation is needed. Blur Image runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Blur Image on a phone or tablet?
Yes. The Blur Image interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your image when I close the tab?
It is discarded. Blur Image keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
