Blur Image — Online Gaussian Blur
Apply a Gaussian blur to the whole image: soften backgrounds, add a frosted look, or play down clutter, with adjustable strength and live preview. Works on desktop, tablet & mobile — batch, local, no upload.
Blurring softens an image and reduces detail. This tool applies a Gaussian blur to the whole image with adjustable strength (radius) — useful for frosted backgrounds, soft textures, or playing down distracting areas. Note this is a whole-image blur, not AI subject-aware background blur (it will not keep a subject sharp automatically). To hide IDs, plates or other sensitive info, use Redact for irreversible coverage. Processing runs entirely in your browser — no upload.
When You Need It
Soft Background / Base Image
Blur a photo into a frosted background or banner base behind foreground text.
Frosted Look
A light blur creates a soft, dreamy visual mood.
Play Down Clutter
Soften a busy background to reduce distraction (not precise redaction).

Blur FAQ
No — this is a whole-image Gaussian blur and does not detect subjects. AI background blur needs a server-side model, which conflicts with our local, no-upload approach, so we do not offer it.
Not safe enough — blur can sometimes be partially reversed. To hide sensitive info, use Redact for irreversible coverage / true pixel removal.
No. Gaussian blur runs locally with the browser Canvas — your image never leaves your device.
Yes — upload a batch, apply one strength to all, then download as a single ZIP.
