How to make a photo blurry on iPhone
Short answer
To make a photo blurry, open it in How to Blur Photo, tap the Full Photo tab so the blur applies to the whole image, choose Gaussian for an even softness or Ghosting for a dreamy look, drag Radius to the strength you want, and tap Save. For a blurry background with a sharp subject, use the Background tab instead.

Sometimes the goal is the opposite of a sharp photo: a soft, blurry image for a lock screen, a backdrop behind text in a story, an abstract of a sunset, or a way to share a moment without the detail. iPhone’s Photos app cannot do it, and web tools mean uploading the file. How to Blur Photo does it on the phone with one tab and one slider.
Built into iPhone
Is there a built-in way?
No. Photos has no blur filter for a regular image. Some people zoom far into a photo and take a screenshot to get a soft result, which destroys resolution. Others use the Portrait f-number slider, which only works on Portrait captures and only on the background. A dedicated blur tool is the clean way.
Styles that suit a fully blurry photo
Gaussian gives an even, out-of-focus look and is best for wallpapers and text backgrounds. Ghosting overlays a shifted copy of the image for a dreamy, slightly surreal result that works well on landscapes and night shots. Motion turns the frame into streaks and suits lights and cityscapes. Crystallize and Hexagonal make abstract, mosaic-like art from any photo.
Radius controls how far the blur goes. For a wallpaper you want app icons to sit on, 70 or above. For a “soft memory” look where the scene is still recognisable, 25–40.
If you actually want only the background blurry
Many people typing “how to make a photo blurry” mean the portrait effect. If that is you, switch to the Background tab: the subject is kept sharp automatically and the same Radius slider controls the background. The guide on blurring the background on iPhone walks through it.

Tips
Blur before you crop to the wallpaper aspect ratio; edges look cleaner.
For text overlays in stories, a Radius around 60 keeps enough colour variation to look alive.

Frequently asked
How do I make a whole photo blurry on iPhone?
Open it in How to Blur Photo, tap Full Photo, choose a style, drag Radius, and Save.
Can I make a photo blurry without an app?
Not in Photos. This site’s free online editor does full-image blur in a browser if you prefer not to install anything; it does not do subject-aware background blur.
Will a blurry photo lose resolution?
The exported image keeps the original pixel dimensions; blur removes fine detail but does not downscale the file.
