How to Blur Photos with Online Photo Editing
When you need to blur a photograph quickly, these days you don't even need to purchase software. Online photo editing can be fast and easy and -- my favorite part -- free. This article will provide you with a step-by-step guideline.
Editing Photos Online
There are a few sites where you can work on your images without installing anything. Some require a registration, but my favorite ones are not only free, but require no downloading and installation, no registration, and work instantly with most web browsers.
While there are a few good sites out there, including Splashup.com, here is my personal favorite easy-to-use online editor that works great for photo blurring (and many other photo needs, from cropping to color correction):
"The most popular online photo editor in the world." This site offers three online editing options. Pixlr Editor is a full suite of tools, similar to Adobe Photoshop. Pixlr-o-matic is mostly a series of Instagram-inspired filters, which saturate, intentionally damage, and degrade your photo for a grungy analog feel. For our purposes, we're going to use Pixlr Express, which is like Pixlr-o-matic in its ease of use and ability to add fun filters, but has more control options from the full Pixlr Editor suite.
For our demo today, we're using a graphic I created using Pixlr Express (if you'd like to use it while following along, simply click on the image and save image as to download it):
To Blur an entire photo, go to http://pixlr.com/express/

To Focal Blur a portion of photo, go to http://pixlr.com/express/, click Browse, Open the a photo and, after clicking Adjustment, select Focal Blur. It's worth noting there are two types of Focal Blur (which you select as buttons next to the Focal Blur icon):
Circular, for when you want the blur effect to radiate outwards from a single point
Linear, for when you want a straight line of focus, surrounded by two sections of blur. This is a great way to mimic Tilt-Shift Photography.
Here's an example of the circular Focal Blur interface. Note the three dots on screen. Adjust the location of the center dot as well as the distance between the center, middle, and outer dots to change how much focus and out much blur there is on your picture.
When Linear Focal Blurring, a forth dot appears, which allows you to tilt your horizontal focus line 45-degrees right or left.
- Blurring -- how out of focus are the outer edges
- Color Boost -- saturates brighter colors between the two solid lines
- Glow Boost -- blows out and softens highlights outside the two solid lines
