Cut out a photo background right on your phone — no app to install

You took the photo on your phone. The subject is fine. The background is a parking lot, a kitchen counter, or half a stranger. Now you want the subject on its own, as a file you can use.

You don't need to install anything for that. Your phone's browser can do it, and the heavy part runs on a server, so an older handset does the job as well as a new one. Below: what your phone already handles alone, where that stops, and the four steps to a transparent PNG in your camera roll.

What your phone can already do (and where it stops)

Worth knowing before you open anything else, because for some jobs the built-in tool is genuinely the fastest route.

iPhone: lift the subject in Photos

On iOS 16 or later, on iPhone XS, iPhone XR and later models, you can touch and hold the subject of a photo and your phone will trace it for you. In the Photos app you get Copy, Add Sticker and Share; in Safari you get Copy Subject. It works across Photos, Messages, Safari, Mail and other apps that accept a paste, and you can AirDrop the result.

The catch is what you're left holding. Apple's flow is built to hand the cutout straight to another app — paste it into a message, keep it as a sticker, AirDrop it to a laptop. It's a longer road when what you need is a PNG file sitting in your storage at full resolution, ready to attach to a listing or hand to a printer.

Android: what Google Photos gives you today

Google has opened up several of its editing tools to everyone in Google Photos — Magic Eraser, Photo Unblur and Portrait Light — with no subscription required, provided your device clears a minimum spec: a Chromebook Plus on ChromeOS 118 or later, or at least 3 GB of RAM with Android 8.0 or iOS 15 and up. Magic Editor is separate: everyone gets a set number of saves per month, and going beyond that means a Pixel device or a premium Google One plan.

Two gaps are worth naming. If your phone sits under that RAM and OS floor — which is exactly the phone most likely to be short on storage for another app — those tools aren't offered to you. And erasing an object is a different job from cutting a subject out: none of it hands you a transparent PNG.

Remove a background in your phone browser, step by step

Four steps, and it's the same sequence on iPhone and Android. Only the folder names change.

1 — Open the tool and pick a photo

Open Safari on iPhone or Chrome on Android, go to the background remover, and sign in. You'll need an account — that's how results are saved to My images, so you can download them again within the retention period (see our Privacy Policy) — but signing up takes under a minute, and new accounts start with a credit balance you can use straight away. Every run shows its cost on the button before you press it.

Tap the upload area and your phone will ask where the photo should come from: Photos on iPhone, Gallery or Google Photos on Android, or the camera if you'd rather shoot it now.

Tip: add the site to your Home Screen. It opens like an app afterwards and still takes no install space.

2 — Fix the HEIC problem first, if you're on iPhone

This is the step that trips people up, and it isn't in the Android version of this guide because Android doesn't have it.

iPhone can save photos in two formats. High Efficiency produces HEIF/HEVC files — the .HEIC ones — which are smaller. Most Compatible produces JPEG and H.264. If a photo won't upload, or arrives somewhere as a file nothing will open, that's the format talking. Switch it in Settings → Camera → Formats, then choose Most Compatible, and every new photo you take will be a JPEG.

That change applies to new photos, not old ones. For a shot you already have, the simplest workaround is to take a screenshot of it and upload that instead, accepting the drop in resolution.

Your phone's own library is not the thing complaining. Google Photos backs up .jpg, .heic, .heif, .png, .webp, .gif, .avif and most RAW files, and takes photos up to 200 MB or 200 MP — so the file is fine where it lives; it is the upload on the other end that has an opinion. One limit there is worth borrowing as a habit: Google Photos won't back up anything smaller than 256 × 256 pixels, and a cutout made from an image that small has nothing to trace either. Send the original, not a thumbnail you saved from a chat.

3 — Let the AI cut out the subject

Press the button and wait. The model finds the main subject and lifts the background away — no lassoing, no brushing along edges, no pinch-zooming to fix a shoulder. Hair, fur and coat collars are the hard part, and they're the part being handled for you.

When it finishes you'll see your subject on a checkerboard pattern. That isn't a background; it's how transparency is drawn on screen. Seeing it means the cutout worked.

4 — Save the transparent PNG to your phone

Tap download. On iPhone the file goes to Photos or Files depending on what you pick; on Android it usually lands in Downloads or the gallery. The background remover returns the PNG clean, without a watermark stamped across it, so it's usable as-is. A copy is also saved to My images in your account, so you can download it again on another device within the retention period.

Getting a clean edge: four things that matter more than the tool

Input quality decides most of the outcome. These four are worth thirty seconds each.

• Light the subject properly. Shooting into a window puts your subject in silhouette, and a silhouette has no edge detail to find.
• Separate the subject from what's behind it. A gray coat against a gray wall is the hardest case there is; one step forward does more than any setting.
• Shoot at full resolution. Screenshots and heavily compressed photos arrive with the fine edges already gone, and they can't be recovered afterwards.
• Keep the subject inside the frame. Anything cropped off at the edge has no outline to trace, so the cut runs flat along the border there.

What to do with the cutout

A transparent PNG isn't the finish line. It's the file that makes the next step easy.

Selling from your phone: Poshmark, Mercari, eBay

Resale apps run on phone photos, and the lead image decides whether anyone taps through at all: Poshmark's guide names that first photo the Covershot and treats it as the entire first impression.

A cutout gets you there without staging anything — subject on clean white, identical across every listing you post. What each platform will actually accept is a separate question with a separate answer per platform, and those answers get revised, so open the current page on the site you sell on rather than trusting a number reprinted elsewhere, this article included. See our seller guide for the marketplace-by-marketplace breakdown: white-background product photos for online marketplaces. And if what's ruining the shot is a person or an object rather than the whole background, that's a different tool.

Printing it: US photo sizes

Cutouts print well because you control what sits behind the subject. The thing to settle first is shape, not size. A 4×6 inch print is a 3:2 rectangle; a marketplace thumbnail is a square; your camera app gives you neither by accident. Those are two different crops of the same picture, and cropping is the one step that throws pixels away for good. So pick the destination before you crop, and keep the full-resolution PNG as the master, because the other crop is still inside it and is not recoverable from a cropped export. Whichever way it goes, put the subject on white before you send the file out — a transparent PNG handed to a print service comes back with whatever that service decides transparency means.

Frequently asked questions

Can I remove a background without downloading an app?

Yes. The whole process runs in Safari or Chrome on the phone itself. Nothing installs, and the processing happens on a server rather than on your handset, which is why an older phone isn't a problem.

Why won't my iPhone photo upload?

It's almost certainly a .HEIC file. Go to Settings → Camera → Formats and pick Most Compatible, which switches new photos to JPEG. Photos already in your library keep their original format.

Is this the same as the iPhone "lift subject" trick?

Same idea, different ending. Apple's version, on iOS 16 and later, is built to copy or share the subject into another app. This one ends with a full-resolution transparent PNG saved to your phone, plus a copy in My images.

Will the result have a watermark on it?

No. The background remover returns the PNG without a mark on it, so it's ready for commercial use.

Does it work on an older Android phone?

Yes, and that's the point of doing it in a browser. The work happens server-side, so a phone that can't run the newer on-device editing tools still gets the same result.

Try it from your phone

Open the background remover on your phone and run one photo through it — a listing shot, a portrait, the pet picture with the laundry pile behind it. A minute tells you whether the edge quality is what you need.
