Soft-focus backdrop
Blur strength 6 on a 1600×1067 café photo softens the whole picture into a calm, out-of-focus backdrop — handy behind overlaid text. The blur applies to the entire image, not just the background.

About
About the Blur Image
Applies a smooth, adjustable-strength blur across a whole photo, then lets you download the result.
Designers use it to create a soft, out-of-focus background for a hero image or text overlay, while anyone wanting a softer look uses it to take the sharp edge off a photo before sharing it. It's one of many free image tools on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.

Fully obscured detail
Blur strength 30 blurs the whole photo so heavily that the writing on the papers can't be read at all — useful for a teaser or background image rather than hiding one small area.

FAQ
Frequently asked questions
Quick answers to common questions about the Blur Image.
What does the Blur Image tool do?
It applies a smooth, adjustable-strength blur across a whole photo and lets you download the result.
Is the Blur Image tool free to use?
Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.
Is my image safe when I use this tool?
Yes. The blur is applied entirely on your own device using your browser's built-in Canvas API — your photo is never uploaded to a server.
Does this blur the whole image or just part of it?
It blurs the entire image evenly. If you only want part of a photo blurred, crop that section out first using the separate Image Cropper tool on this site, blur it, then recombine as needed in an image editor.
How strong can the blur be?
The blur strength slider goes from a subtle soft-focus touch up to a heavy blur strong enough to fully obscure detail — use whichever level suits what you're making.
Does blurring reduce image quality elsewhere?
No. Only the blur effect itself is applied; the image isn't otherwise recompressed or resized.
Can I use the Blur Image tool on my phone?
Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.
Does the Blur Image tool have any limitations?
It applies one uniform blur across the whole photo; it doesn't support blurring just a selected region or a specific face automatically.
