About Image Blur
Image Blur provides a dedicated, focused workspace: Apply a Gaussian blur with adjustable radius. Perfect for backdrops, privacy redaction and generating hero-section overlays. Using it is a three-step job: 1) Load your image, 2) Slide the blur radius from 1 to 40 pixels, 3) Download the blurred PNG when you're happy. Processing depends on the specific operation. Any external lookup or service should be identified near the tool controls.

Review any usage notes shown on this page before relying on its availability.

Why this matters
Images are usually the heaviest thing on a web page, which makes them the single biggest lever you have over load time, Core Web Vitals and bounce rate. A hero image that drops from 1.8 MB to 180 KB can shave whole seconds off a mobile page load on a 4G connection.
Common Mistakes to Avoid
Uploading camera-resolution photos to a 1200px container
The browser downloads all 6000 pixels and throws most away. Resize to roughly twice the display width, no more.
Re-compressing an already-compressed JPEG
Each save cycle bakes in more artefacts. Always start from the original file, not from a copy you exported yesterday.
Forgetting a background fill on transparent PNGs
Converting PNG to JPEG without choosing a fill colour turns transparency into black. Pick white or your brand colour explicitly.
If you came here from the Batch Image Processor, keep Image Resizer open in a second tab.
Key Terms Explained
- WebP
- A modern image format supported by every current browser that typically saves 25–35% over JPEG at the same perceived quality.
- Lossy vs lossless
- Lossy compression discards data you're unlikely to notice for far smaller files; lossless preserves every pixel but saves much less.
- EXIF orientation
- Metadata written by phone cameras that tells software how to rotate the photo. Ignoring it is why uploads sometimes appear sideways.
- LCP
- Largest Contentful Paint — the Core Web Vital that usually measures how quickly your hero image finishes rendering. Aim for under 2.5 seconds.
Industry Best Practices
- Read the field labels, units, and instructions before using Image Blur.
- Keep a copy of important source material when the operation could change or transform it.
- Review the result before sharing or relying on it; check the page for available copy or download controls.
- Cross-check consequential results against an authoritative source; this tool does not replace professional advice.
- Review Image Blur's data-handling notice before entering sensitive information.
Popular Use Cases
- Case 1Prep product photos, hero banners and blog covers for the web.
- Case 2Compress screenshots for tickets, docs and Slack without a native app.
- Case 3Resize social graphics to Instagram, Twitter, LinkedIn and OG-image specs.
- Case 4Batch-process large uploads for e‑commerce, portfolios and newsletters.
Pro Tips & Best Practices
- Choose an output format supported by your destination; JPEG and WebP do not preserve transparency.
- Compare dimensions, visual quality, and byte size after export; compression results depend on the source and settings.
- Check the individual tool's accepted formats, batch support, and data-handling notice before processing sensitive images.
How to use Image Blur

Frequently Asked Questions
Can I use it to redact private info?›
For real redaction use the Pixelator or a dedicated tool — a strong blur can sometimes be partially reversed. For casual privacy, blur is fine.
Is the blur radius the same as Photoshop?›
It matches the CSS filter blur spec, which is a Gaussian blur. Values are directly comparable.
Which image formats does Image Blur support?›
Accepted input and output formats depend on Image Blur. Check the file picker and controls on this page; browser support can also vary by format and device.
Is Image Blur free to use?›
Yes — Image Blur is completely free with no signup, watermark, trial or hidden paywall, however often you use it.
Are my photos uploaded to a server?›
Check the data-handling notice shown with Image Blur. Some image tools process files in the browser, while other features may send data to a named service.
Does Image Blur work on mobile phones and tablets?›
Yes. The layout is mobile-first and tested on iOS Safari, Android Chrome and every current desktop browser, with tap targets sized for thumbs.
Will Image Blur reduce my image quality?›
It depends on the operation and output settings. Lossy encoding can reduce quality, and changing formats does not guarantee a smaller file. Compare the result with the original.
Is my data safe when I use this blur image?›
Data handling varies by tool. Read the notice above the workspace to see whether your input stays in the browser or is sent to a named provider or service. Avoid entering sensitive information unless you understand that tool's handling.
How large a file can this blur image handle?›
The practical limit depends on the accepted format, browser, device memory, and the operation. If processing fails, try a smaller image and check the specific error or file guidance.
How is Image Blur different from other online blur image tools?›
It does one job without pop-ups, forced sign-in or interstitials, and remembers your settings between visits so repeat work takes seconds.
