Questions people ask

Is this blur tool free?
Yes. Image and video blur are free: no account, no watermark, and no sign-in. Your files are processed in this browser tab on your device.
Does BlurThis upload my file to your servers?
No. You pick a file from your phone or computer and the editor processes it in this browser tab. Your image or video is never sent to BlurThis servers or stored by us. Many other free tools ask you to create an account first, then upload your file to their cloud. We do not work that way. Closing the tab clears it from memory. How to check that for yourself.
Can I blur part of a video?
Yes. On the Video tab, choose a clip from your device, trim up to 90 seconds, place a blur box, mark Blur In and Blur Out for timing, then download. Step-by-step video blur guide.
Can I blur only one part of an image?
Yes. That is the normal way. Drag a box over one region (a face, an email, a house number) and leave the rest sharp. Blur one part, keep the rest.
