Photo Blur is a free browser-based photo tool from utils.sbs. Apply a tasteful Gaussian blur for backgrounds and privacy. It is built for quick, focused jobs: open the page, add your input, adjust the options and take the result with you. No account, install or server upload is required.

Images are decoded and transformed with the Canvas API. Filters, resizing and format conversion happen locally, so the source file is never sent over the network.

1. 1Open Photo Blur and add your input.
2. 2Adjust the options: blur radius.
3. 3Run the tool, check the preview or result, and download the output.

• Prepare an image for a website, email or social post.
• Convert between modern image formats without a desktop editor.
• Reduce file size or crop a screenshot before sharing it.

Blur radius

Set this value before running the tool.

Very large images can hit the device's memory limit, and output quality depends on the browser's canvas encoder.

Photo Blur processes its input in the browser whenever the platform API allows it. Files and values are not uploaded to a server for processing, and the tool does not require an account. For calculations, use the result as a reference and verify important decisions against the source formula or a qualified professional. Read our methodology.
