What is a blur image tool?

A blur image tool softens a photo by averaging neighboring pixels, so sharp edges melt into a smooth wash. Blur the whole image for a defocused look, or blur just the background to fake portrait-mode depth of field.

Our blur tool runs entirely in your browser: upload a photo, pick a mode and strength, and download — no signup, no install, nothing uploaded.

Features

Why use it

Two modes

Blur the whole image, or keep the subject sharp and blur only the background.

Adjustable strength

From a subtle soften to a heavy bokeh, slide the strength to taste.

Runs in your browser

Frequently asked questions

Is the blur image tool free?

Yes — completely free, no signup, no watermark. The blur runs in your browser, so there's nothing to pay for or log into.

How do I blur an image?

Upload the photo, pick a mode — Whole image to soften the entire photo, or Background to blur only behind the subject — set the strength, and click Blur. Download a soft PNG or JPG.

How do I blur the background of a photo?

Choose the Background mode, set the strength, and click Blur. The subject stays sharp while the area behind it is softened. It works best on a photo with a plain backdrop and a clear subject.

How do I blur an image for free?

Use our free in-browser blur tool — no signup, no install. Upload the photo, pick a mode and strength, click Blur, and download. Nothing is ever uploaded to a server.

Can I blur just the background and keep the subject sharp?

Yes. Background mode finds the subject, keeps it sharp, and blurs only the background — the portrait-mode bokeh look. For the cleanest edge, use a photo where the subject stands out from a plain background.

How do I blur a picture on my phone?

Open this page in your mobile browser, upload the photo, pick a mode, and download. Because the tool runs in the browser, it works the same on iPhone and Android — no app required.

Does blurring reduce image quality?

No. Blurring is an intentional softening, not quality loss — no detail is destroyed, it's just defocused. Export as PNG to keep the file clean around the subject's edge.

How do I blur an image in Photoshop?

For the whole image, apply Filter ▸ Blur ▸ Gaussian Blur. For the background only, select the subject (Select ▸ Subject), add a layer mask, invert it, then apply Gaussian Blur to the background. A one-click online blur tool does both without the masking.

Can I blur an image in Canva or Picsart?

Both have blur effects. For a free, no-signup alternative that runs in your browser and never uploads your photo, upload it to our blur image tool instead.

Is this a Snapseed alternative for background blur?

Yes. deervo gives you the same one-click background blur, plus a whole-image mode, adjustable strength, a free in-browser demo, and no app to install.
