Image Blur
Upload an image, adjust blur strength, preview the result, and download the blurred version. Useful for privacy masking, background effects, and quick visual edits.
Upload an image, adjust the blur radius, choose an output format, then render and download. Transparent images exported as JPEG need a background fill.
Privacy: blur processing runs locally in your browser. No image data is stored or transmitted.

How it works
This tool uses the browser canvas to render your uploaded image, applies a blur filter based on the selected radius, and then exports the result in your chosen format. Blur strength changes the visual softness of the image, while format and quality affect final size and compression.
- Blur radius: controls how strong the blur looks
- Format: affects both appearance and file size; PNG is lossless, while JPEG and WebP are compressed
- Quality: only applies to JPEG and WebP and changes compression strength
- Result interpretation: light blur keeps shapes recognizable, while strong blur removes detail and is better for masking text, faces, or background elements
Examples
- Privacy masking: blur names, email addresses, license plates, or faces before sharing screenshots
- Background effect: blur a photo to create a soft backdrop behind text or UI mockups
- Focus control: reduce detail in secondary areas so attention stays on the main subject
- Quick edit workflow: useful when you need a fast browser-based blur without opening full image-editing software

About this tool
This tool helps you process and convert images directly in your browser. It runs entirely in your browser without sending data to a server.
You can use this tool when optimizing images for web use or changing formats. The results should be interpreted as a modified image with updated format, size, or quality.
FAQ
- How does this image blur tool work?
It draws your image onto a canvas, applies a browser-based blur filter, and lets you preview or download the result.
- Does this upload my image?
No. The entire blur process runs locally in your browser.
- Can I adjust blur strength before downloading?
Yes. You can change the blur radius and quality settings, then re-render the result.
- Which formats can I export?
You can export as PNG, JPEG, or WebP depending on your browser's image encoder support.
- Will blur reduce file size?
Sometimes, but not always. File size depends on both image content and the selected output format and quality.
- When should I use image blur?
Use blur when hiding sensitive information, reducing background detail, or creating depth in layouts and mockups.
- Can too much blur affect image quality?
Yes. Strong blur can remove important detail and make text, faces, or UI elements hard to recognize.
