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. Processing can still take time while the file decodes, models download, or a video encodes. Delay is not proof of an upload. A Network panel check has to include images, media, and other requests, not only Fetch/XHR, and request size alone is not proof. Offline use after the page has loaded is useful evidence of local capability; it does not prove that an online session never transmits anything. Closing or refreshing the tab drops the working copy from this page; that is not a forensic wipe of device memory or disk. How to check that for yourself.
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.
Can I blur part of a video?
Yes. On the Video tab, choose a clip from your device. Files over 50 MB are rejected. Trim up to 90 seconds per download (longer clips can load, then trim). Preview and export scale so the longest edge is 720 pixels. Place a blur or pixelate box, mark Blur In and Blur Out, then download. There is no opaque black bar on video.
