Blurring the background of a photo is one of the simplest and most effective ways to give your images a professional look. This effect helps highlight the main subject, reduces distractions in the background, and adds depth to your composition — all without needing a professional camera.
The good news is that there are several free and easy-to-use apps that simulate the blur (bokeh) effect right on your phone. In this article, you’ll learn how to apply this effect using the best apps and get tips for making it look natural and polished.
1. What is the blur effect?
Also known as the bokeh effect, this soft background blur is commonly seen in DSLR camera photos. It helps isolate the subject from the background, creating a cleaner, more artistic, and elegant look.
Today, anyone can apply this effect with just a tap, using artificial intelligence, auto-select tools, or manual adjustments — all through mobile editing apps.
