Blur Image

Apply an adjustable Gaussian blur to an image, right in your browser.

Blurring an image serves a range of practical purposes — softening a busy background so a subject stands out, obscuring a sensitive detail before sharing a screenshot, or just creating a soft-focus aesthetic effect — and a quick adjustable blur tool handles all of these without needing a full photo editor.

This tool applies a real Gaussian blur using the browser's native Canvas filter API, the same blur algorithm used across modern web and design software, with a strength slider that controls how soft the effect is. Higher values produce a more pronounced blur; lower values give a subtle softening.

Processing happens entirely client-side, so there's no upload wait and your image never leaves your device.

Frequently asked questions

Common mistakes to avoid
