How to blur the background of an image online
This background blur tool runs entirely in your browser. It combines full-image Gaussian blur,
portrait-style background blur and a brush-based selective blur so you can protect sensitive details
or add a professional depth-of-field look without opening heavyweight desktop software.
Upload one or more JPG, PNG or WebP images from your device.
Choose a blur mode:
Full-image blur, Portrait background blur or Brush-based selective blur.
Adjust the blur strength slider to control how soft or strong the blur looks.
In portrait mode, use the focus radius slider to set how much of the centre stays sharp.
In brush mode, click the “Brush blur” button next to a file to paint blur exactly where you need it.
Click “Start batch blur” to process all selected images for full or portrait blur modes.
Download each result individually, or use “Download all as ZIP” to grab everything in one go.
When to use full-image blur vs background blur vs brush blur
Different blur modes are useful in different situations:
Full-image blur: great for turning a busy photo into a soft background for text, UI mockups, product shots or presentations.
Portrait background blur: ideal for profile photos, LinkedIn headshots, avatars and thumbnails where the person should stay sharp but the background should fade away.
Brush-based blur: best for hiding sensitive information like licence plates, email addresses, usernames, notes on a whiteboard or parts of a screenshot.
Why use this online background blur tool?
Many background blur apps require uploads, accounts or watermarks. This tool is designed to be
lightweight, privacy-friendly and fast:
No uploads stored: all processing happens in your browser, and images are never saved to a server.
No watermarks: exported images are clean and ready to use in your projects.
Batch-friendly: blur one image or dozens in a single session and download them all as a ZIP file.
Multi-format support: works with JPG, PNG and WebP and can export to JPG to keep file sizes small.
Where can I use blurred-background images?
Once you’ve blurred the background of your images, you can reuse them nearly anywhere:
Profile pictures on LinkedIn, X (Twitter), Instagram, TikTok and Facebook.
YouTube thumbnails, Reels and Stories covers, or podcast episode artwork.
Website hero backgrounds, blog graphics and presentation slides.
Screenshots shared in documentation, Slack, Teams, Discord or support tickets.
Is this background blur tool free?
Yes. This background blur tool is completely free to use and has no signup, login or watermark.
You can run as many blur sessions as you like and experiment with different modes and strengths
until your images look exactly how you want.
