All processing runs in your browser. Your images never leave your device, not even for a moment.
Built Around What Actually Matters
Three decisions that make this tool faster and more trustworthy than most alternatives.
Privacy First
Your Images Stay on Your Device
Every blur operation runs entirely inside your browser. Nothing is uploaded to a server — close the tab and nothing is left behind. You stay in control of your files at every step.
Three Blur Types
Gaussian, Stack, or Box — Your Call
Most online tools offer one blur type and call it done. Here you get three distinct effects with precision sliders, so the result matches what the image actually needs.
Zero Friction
No Account, No Watermark, No Waiting
Open the page and the tool is ready. No sign-up form, no software to install, no watermark on export. Pick a blur type, move the slider, download — that is the whole process.
What This Tool Does Well
Six built-in features covering the most common blur tasks — all free, no sign-up.
Gaussian, Stack & Box Blur
Each type produces a different visual result. Gaussian softens evenly, stack gives a fast, balanced blur, and box delivers a flat geometric spread. Switch between them in one click.
Instant Feedback as You Adjust
Drag the intensity slider and the canvas updates immediately. No apply button, no processing delay — what you see is exactly what you get before you download.
Free to Use, Every Single Time
No plan tier, no daily limit, no watermark on the output. Every feature on this page is available on every visit with no strings attached.
Processed Locally, Seen Only by You
The blur runs directly on your device using the browser's built-in canvas API. Your image is never transmitted, never stored, and never seen by anyone but you.
Ready the Moment You Arrive
No account, no email, no download prompt. Open the page, upload your image, and the tool is already waiting. Nothing stands between you and a finished edit.
Precision Controls for Every Use Case
Set blur intensity from a light softening to a full redact with the slider. Combine blur type and intensity to match exactly what the image calls for.
How to Blur an Image
Three simple steps — no account, no software, no learning curve.
1
Upload Your Image
Drag your file onto the canvas or click to browse. JPG, PNG, and WebP are all supported — no conversion needed before you start.
2
Choose a Blur Type & Set the Intensity
Select Gaussian for soft, even blur; stack for a fast, balanced blur; or box for a flat geometric spread. Move the slider and the canvas updates instantly — no apply button.

When to Use Image Blurring
From privacy protection to creative design — here are the most common reasons people blur an image online.
Protect Sensitive Information
Blur faces, phone numbers, email addresses, or ID details in screenshots before sharing. Useful for work communications, shared documents, or any post where part of the image needs to stay private.
Add Depth of Field to Your Photos
Soften the background of a portrait or street photo to draw the eye to your subject. It's the look you'd normally need a fast lens to achieve — done in a browser in a few seconds.
Create Blurred Backgrounds for Design Work
Turn any photo into a soft backdrop for posters, slides, or websites. A blurred layer gives overlaid text more contrast and makes the layout easier to read at a glance.
Make Products Stand Out
Blur the background of a product photo so the item is the only thing drawing the eye. Works well for online listings, catalogue pages, and social posts where a focused shot converts better than a busy one.
From People Who've Used It
Here is what brought them to the tool — and why several came back.
Avery Chen
“I found it while trying to blur a screenshot quickly, and it has stayed in my workflow ever since.”
Jonas Meyer
“Having three blur types in one place is more useful than I expected. Gaussian is what I reach for most, but stack blur has become a solid default for quick edits.”
Kenji Sato
“I needed something quick before a meeting and had never used this site before. Uploaded, adjusted, downloaded — under two minutes. That was enough to bookmark it.”

Frequently Asked Questions
Quick answers for the most common blur image online questions.
Yes, completely free. There are no hidden fees, no feature limits, and no watermark on your exported images. You can blur as many photos as you need without signing up or subscribing.
Your images are processed entirely in your browser. Nothing is uploaded to any server. Once you close the page, no data remains anywhere — not on our end, and not in your browser cache.
You can upload JPG, PNG, and WebP images. The processed result can be downloaded in all three of those formats as well. If you choose JPG, a quality slider lets you balance file size against image fidelity before saving.
The tool offers three blur types. Gaussian blur applies smooth, even softening in all directions — good for most tasks. Stack blur produces a fast, balanced soft blur that works well for general editing. Box blur averages each pixel with its neighbors uniformly, giving a flatter, more geometric result. Each produces a visually distinct look.
Yes, and there are two ways to do it. Rectangle mode lets you draw one or more areas to target — only those regions get blurred. Brush mode lets you paint blur onto specific spots freehand. Both approaches leave the rest of the image untouched, which is useful for hiding faces, phone numbers, addresses, or any other detail you need to keep private.
No. The tool runs directly in your browser — no installation, no sign-up, no email required. It works on all major browsers including Chrome, Firefox, Safari, and Edge.
Gaussian blur softens evenly in all directions with a natural, gradual falloff — it is the best default for background blur, portrait softening, or hiding sensitive information. Stack blur creates a balanced soft blur with strong performance, making it useful for quick general-purpose edits. Box blur averages each pixel with its surrounding neighbors uniformly, producing a flatter, more geometric result than Gaussian. When in doubt, start with Gaussian.
