How to Blur the Background of a Photo (2026): iPhone, Android, Canva and Photoshop

How to blur the background of a photo: on an iPhone, open a Portrait photo, tap Edit and drag the f-number slider down (f/1.4 to f/2.8 gives strong blur). On Android, use Portrait Blur in Google Photos. For any other photo, Canva's Auto Focus or Photoshop's Lens Blur adds the blur in under a minute, with no new shot needed.

Blur works by mimicking a wide-aperture lens: the subject stays sharp and everything behind it melts into soft color. Phones fake this with depth data or AI masks, and the result depends on how cleanly the software finds the edge of your subject. This guide covers each method step by step, how to avoid the smeared edges that give fake blur away, and when a product photo is better served by a clean background instead of a blurred one.

How do you blur the background of a photo on iPhone?

If you shot in Portrait mode, you can change the blur any time afterwards in the Photos app. Portrait photos store a depth map alongside the image, so the blur isn't baked in.

1. Open the photo in Photos. Portrait photos show a Portrait badge in the top corner.
2. Tap Edit (the slider icon on recent iOS versions).
3. Tap the ƒ (Depth) control. A slider appears with f-numbers.
4. Drag toward lower numbers (f/1.4–f/2.8) for more blur, or higher (f/8–f/16) for less.
5. Tap Done. You can return later and change it, or tap Portrait to turn the effect off entirely.

Newer iPhones (iPhone 15 and later) can save depth data automatically when they detect a person, pet or close subject, even in the normal Photo mode, so the Portrait option may appear on photos you didn't shoot in Portrait. Menu names move between iOS versions, so if the ƒ button isn't where you expect, look for the Portrait or Depth control in the edit screen.

If the photo has no depth data at all, the iPhone's Photos app can't add blur. Use Canva, Google Photos (it runs on iPhone too) or one of the AI options below.

Getting a better Portrait shot in the first place

• Stay within about 0.5–2.5 m of the subject; Portrait mode tells you if you're too close or far.
• Move the subject away from the wall. Distance behind the subject does more for blur than any slider.
• Avoid fine, messy edges (frizzy hair, wire whisks, see-through glass) where depth maps struggle.
• Use good light. In dim light, the depth map gets noisy and edges look cut out.

How do you blur a photo background on Android?

Use Google Photos' Portrait Blur, which is available free on most Android phones. It estimates depth with AI, so it also works on many photos that weren't shot in portrait mode.

1. Open the photo in Google Photos and tap Edit.
2. Go to Tools (or Actions) and tap Blur or Portrait.
3. Drag the blur strength slider. Tap the subject to change the focus point if offered.
4. Tap Done, then Save copy to keep the original.

Samsung Galaxy phones have a similar option in the Gallery app: open a photo shot in Portrait mode, tap Change background effect and pick Blur, then set the strength. Google Photos' editor layout varies by phone and region, and Google has changed which AI tools are free over the years, so check for a subscription prompt before relying on it.

How do you blur a background in Canva?

Canva's Auto Focus effect detects the subject and blurs everything behind it, and Canva lists it as available on its free plan.

1. Upload the photo and add it to a design.
2. Click the photo, then Edit (or Edit photo).
3. Choose Auto Focus under effects.
4. Adjust Blur intensity and, if shown, the focus position.
5. Download as JPG or PNG.

Canva also has a plain Blur adjustment, but that blurs the whole image. Auto Focus is the one that keeps the subject sharp.

How do you blur a background in Photoshop?

Use Photoshop's AI Lens Blur, which builds a depth map and renders realistic lens blur in a few clicks. Adobe has moved it between places over recent versions, so you may find it in one of two spots:

• Camera Raw Filter > Lens Blur (also in Lightroom desktop): tick Apply, set the blur amount, then click or drag to choose the focus range.
• Filter > Neural Filters > Depth Blur in versions that include it.

For full control, the manual way still works: select the subject (Select > Subject), invert, and apply Filter > Blur Gallery > Field Blur or a Gaussian Blur to the background layer. Refine the edge with Select and Mask first, or you'll get a halo. Lightroom mobile also has Lens Blur, but Adobe lists it as a Premium feature.

Which method should you use?

How do you make fake blur look real?

Real lens blur grows gradually with distance, so the most convincing edits blur the far background more than the area right behind the subject. A flat, even blur across everything is the giveaway.

• Go lighter than you think. Around f/2.8–f/4 equivalent looks natural; f/1.4 on a phone often smears edges.
• Check the edges at 100% zoom. Look at hair, handles, straps and the gaps between fingers. Fix spots with the focus brush if the tool has one.
• Keep the ground sharp near the subject. A table or floor should go soft gradually, not instantly.
• Match noise. Heavy blur removes grain, so a blurred area can look plastic next to a grainy subject. Many editors add grain back automatically; if not, add a touch.

Should product photos have a blurred background?

For main listing images, no: Amazon, Walmart and Google Shopping want the product on a plain, usually white background, and a blurred room behind it can count as a lifestyle shot. Blur works well for secondary images, social posts and ads, where context sells the product.

For a lifestyle look, a real shallow depth of field beats added blur: shoot the product 1–2 m in front of a window or shelf, get close, and tap to focus on the label. If the shot is already taken and the background is a mess, it is often quicker to replace it than to blur it. Our guides on changing the background of a photo and lifestyle product photography ideas cover both routes.

Using AiArter for product backgrounds

AiArter is built for product photos, so it offers a few ways to get a background that doesn't compete with the product:

• AI image editor (8 credits). On the edit image with AI page, type “blur the background” and it edits the photo from your description. Because it regenerates the image, check small text on labels afterwards.
• Lifestyle scenes (8 credits). The AI background generator cuts the product out of your photo and keeps it as-is, then generates a scene behind it such as Marble counter, Wooden table or Living room. You can describe a soft, out-of-focus scene yourself.
• Plain backgrounds (4 credits). White, light grey or a brand color for main images, from the product photo tools.

If the photo itself is soft rather than the background, blur won't help; see how to unblur a photo instead.

Frequently asked questions

How do I blur the background of a photo I already took?

On iPhone, open a Portrait photo, tap Edit and drag the ƒ slider. On Android or any phone, use Google Photos' Portrait Blur. On a computer, Canva's Auto Focus or Photoshop's Lens Blur work on any photo without depth data.

Can I add background blur to a non-portrait photo on iPhone?

Not in the iPhone Photos app unless the photo saved depth data, which newer iPhones do automatically for people, pets and close subjects. For other photos, use Google Photos, Canva or an AI editor.

What f-stop gives the most background blur?

Lower f-numbers give more blur. On an iPhone slider, f/1.4 to f/2.8 gives strong blur, though f/2.8 to f/4 usually looks more natural because edges stay clean.

Is there a free app to blur the background of a photo?

Yes. Google Photos (Android and iPhone), the iPhone Photos app for Portrait shots, Samsung Gallery and Canva's free plan all blur backgrounds. Google and Canva have changed plan features before, so watch for an upgrade prompt.

Why does my blurred background look fake?

Usually the edges around hair or thin parts are smeared, or the blur is the same strength everywhere. Use less blur, fix edges with a focus brush, and keep the ground near the subject sharper than the far background.

Can I use a blurred background on Amazon product photos?

Not for the main image, which must be on pure white. A blurred lifestyle setting is fine for secondary images, where it shows the product in use.
