Free blur tool for photos, screenshots, and short videos. Runs in your browser on your device.
How to blur an image in three steps
- 1
Open your image
Choose a photo or screenshot. It stays in this tab.
- 2
Cover the private bit
Drag a box over a face or a name. Use Black bar for emails, phones, and card digits.
- 3
Download the PNG
Share that copy—not the original.
Numbers and codes? Use a black bar. More detail on how it works.
How to blur part of a video online
Open a short clip, trim, place a timed blur box, then download. Start on the video blur tool.
Who this is for
Support agents paste ticket snips into chat. Marketplace sellers crop driveway photos. Parents blur classmates before a school group post. Developers black-bar tokens before a GitHub issue. BlurThis is built for those five-minute privacy jobs where installing desktop software is slower than the send button you are staring at.
The editor is deliberately small. There is no account wall, no cloud library, and no “enhance with AI” upload. You open a file, cover what should stay private, download, and leave. If you need a longer walkthrough for one platform or one risk, the guides under Blog go deeper without replacing this homepage canvas.
One editor, five common privacy jobs
BlurThis is a browser canvas for files you are about to send. Pick the Image or Video tab above, cover what must stay private, then download from the same tab. Nothing goes to a BlurThis upload queue. That is the whole product promise in one sentence.
Most people arrive with one concrete mess: a face in a hallway photo, a plate on a marketplace listing, an OTP toast in a support snip, or a short screen recording that shows an inbox. The tool links below open the same editor with wording tuned to that job. Use them when you want a focused landing; use this homepage when you already know the file type and just want to start.
When blur is enough, and when a black bar is safer
Soft blur or pixelate works for faces and messy backgrounds where a glance is the risk. Short, high-contrast strings are different. Passwords, OTPs, card digits, and API keys can still be guessed from a light smear. Prefer an opaque black bar for those, then export PNG so chat apps start from a solid fill. The blur vs black bar guide spells out the tradeoffs without turning this page into a device tutorial.
Pick a focused tool when the job is narrow
- Blur a face for bystanders and Find faces suggestions
- Blur a screenshot for ticket chrome, sidebars, and title bars
- Blur text for passwords, keys, and account numbers
- Blur a number plate for driveway and dashcam stills
- Blur part of a video for short clips with timed boxes (Video: 50 MB in, 90 seconds out, 720-pixel longest edge. No opaque black bar on video.)
Before you hit send
Open the downloaded file at full size. Sharing the original by mistake is the most common fail. Prefer PNG for stills when you can. For a careful check that the file never left your tab, read how to verify local processing. Cornerstone walkthroughs for screenshots and video live in the screenshot guide and the video blur guide.
