About Image Blur

What this page solves

Image Blur solves the privacy and friction problem of typical online tools — it never uploads, never asks for a signup, and runs in your browser.

Image Blur is a free in-browser image tool that lets you apply gaussian blur to images without uploading your photos to any server. It is built for designers, content creators, marketers, and everyday users who need quick, private image edits — whether you are preparing assets for a website, resizing photos for social media, or compressing files before sending them by email. All processing uses your browser's Canvas and Web APIs, so your images stay on your device the entire time. Image Blur uses the browser's hardware-accelerated Canvas pipeline — the same one Photoshop's web build uses — so the output matches a desktop editor pixel-for-pixel. EXIF metadata (camera model, GPS coordinates, capture date) is read locally — useful when you need to inspect a photo's origin without trusting a third-party "EXIF viewer". Image Blur loads as a small bundle and is interactive within a second on mid-range phones, so it is practical to use it from a phone while away from a desk. There are no watermarks, no quality compromises from third-party servers, and no waiting in upload queues. Image Blur is part of our Image Tools suite — a unified set of tools for every step of an image workflow. If you also need a complementary utility, try our Image Resizer. It is free, has no signup, and works with the formats you actually use: JPG, PNG, WebP, GIF, SVG, and BMP.

Frequently asked questions

How to use Image Blur?

When should I use Image Blur?

Use Image Blur whenever you need a fast, private, browser-based way to apply gaussian blur to images.

Is Image Blur safe?

Yes. Image Blur runs 100% in your browser. Inputs are never uploaded, stored, or logged — safe for confidential content.

Will quality be affected by Image Blur?

Quality is preserved unless you explicitly choose a lossy format or low quality setting.

What formats does Image Blur support?

Image Blur supports JPG, PNG, WebP, GIF, BMP and SVG (where applicable)

Is Image Blur free?

Yes — Image Blur is completely free, with no registration, no watermarks, and no usage limits.

Are my images uploaded to any server?

No. Image Blur processes images entirely in your browser using the Canvas API. Your photos never leave your device.

What image formats does Image Blur support?

Image Blur works with all common web formats including JPG, PNG, WebP, GIF, SVG, and BMP, depending on the operation.

Will I lose quality?

Image Blur uses the browser's native image pipeline. Where compression is involved, you can usually control the quality level — otherwise the output is lossless.

Why is Image Blur better than a desktop editor for quick edits?

Time-to-first-edit. Opening Photoshop or Affinity for a single resize takes 10–30 seconds. Image Blur is one tab away and produces the same output for everyday operations. Keep desktop tools for masking, retouching, and complex compositing.
