Blur an image or redact sensitive details
Blurring is one of the fastest ways to protect privacy in a photo. Whether you are posting a picture that happens to include a bystander, sharing a screenshot that shows an email address, or documenting an incident that reveals a license plate, a well-placed blur removes identifying information while keeping the rest of the image intact. Pixohub gives you two modes: blur the entire image for a soft background or backdrop effect, or draw rectangles over just the regions you need to hide.
Drawing boxes over faces and plates is the go-to workflow for redaction. You simply drag a rectangle across each area you want to obscure, and Pixohub applies a strong blur inside those regions. You can add as many boxes as you need, so a group photo with several faces or a street scene with multiple vehicles can all be protected in a single pass. An adjustable strength control lets you decide how heavy the blur should be — light enough to soften, or heavy enough to make the underlying detail unrecoverable.
Blurring is also a creative effect. A gentle blur across an entire image creates a dreamy, out-of-focus look that works well as a website background, a placeholder, or a backdrop for text overlays. Because the effect is applied on a canvas, you can preview the result instantly and dial the intensity up or down until it looks exactly the way you want.
Why privacy-focused blurring matters
When you redact an image, the last thing you want is for the sensitive data to leak on its way to being hidden. Many online blur tools upload your file to a remote server to process it, which means your private screenshots and photos briefly live on someone else's machine. Pixohub avoids this entirely: all blurring happens locally in your browser using the HTML Canvas API. The image never leaves your device, so there is no upload, no server storage, and no risk of interception.
For true redaction, use a strong blur setting. A light blur can sometimes be partially reversed by determined attackers, so when you are hiding something that genuinely must stay secret — an account number, a home address on a document, or a person's face — turn the strength up so the underlying pixels are thoroughly scrambled. The result is baked directly into the exported image, so the hidden information is gone from the file you share.
Because everything runs on your device, there are no file size limits beyond your device's memory, no queues, and no cost. You can process one image or dozens in a row, all for free and without creating an account. This makes Pixohub a practical choice for journalists, support teams, and anyone who regularly needs to share images while protecting the people and details captured in them.
