What the tool actually does
The background remover runs a segmentation model (IS-Net) inside your browser. It looks at every pixel and decides how likely it is to belong to the main subject — a person, a product, a pet, a logo — and turns everything else transparent. Edge pixels get partial transparency, which is why hair and soft edges don't look cut out with scissors.
Nothing is sent to a server. The only thing downloaded is the engine itself: about 40 MB, fetched the first time you tap the upload box or drag a file onto it (not just by opening the page). Later runs on the same browser usually start much faster.
Step by step
- Tap Choose an image or drop a file. JPG, PNG and WebP go straight to the model; HEIC from an iPhone, AVIF and other formats your browser can read are converted to PNG first, automatically.
- Wait for the cut-out. On a laptop it takes a few seconds; on an older phone it can take noticeably longer — the progress bar keeps moving while the model works.
- Choose the background: transparent, white, black, or any colour from the picker.
- Download. The file is always a PNG named
yourphoto-nobg.png.
One image at a time: the model is heavy, and processing files one by one keeps the tab from running out of memory on phones.
Which photos give the cleanest result
The model is good at one clear subject that stands apart from its surroundings. You'll get the best edges when:
- the subject is in focus and the background is softer or simpler;
- there's colour or brightness contrast between subject and background (a dark coat on a dark wall is hard);
- the subject isn't cropped awkwardly at the frame edge.
Expect weaker results with glass, smoke, fine fur against a busy background, thin objects like bicycle spokes, and group photos where it's unclear what the "subject" is. Shadows on the floor are usually removed, which can make product shots look like they're floating — add a soft shadow later in a design app if you need one.
Transparent, white or coloured — which to pick
| You need it for | Pick | Why |
|---|---|---|
| Logos, stickers, design layouts | Transparent | Drops onto any background |
| Marketplace listings, ID-style photos | White | Many forms and shops want a plain light background |
| A brand colour or a profile banner | Custom colour | Matches your design exactly |
If an app shows your transparent PNG on a black background, the file is fine — some messengers and phone galleries simply preview transparency as black. Choose White if the image will be viewed in such apps.
Large images and file size
Very large photos are scaled down before processing — anything over 4096 px on the long side or about 16 megapixels. A 48 MP phone photo therefore comes back smaller than the original, which is still plenty for web, print at normal sizes and social media.
Transparent PNGs are bigger than JPGs. If you picked a solid background and need a small file for an upload form, convert it with PNG to JPG and then shrink it to a target such as 200 KB. Keep transparent logos as PNG — JPG cannot store transparency and would fill it in.
What to do next with the cut-out
- Trim the empty space around the subject with Crop Image.
- Make a round avatar: Circle Crop on the result gives a transparent circle.
- Set an exact size for a profile or a listing with Resize Image or a preset like Profile Picture.
- Before posting a photo of yourself or your home, check what's hidden in the original file with the EXIF viewer. The PNG you download here is a freshly encoded image, so camera data and GPS from the original are not carried over.
Troubleshooting
- "Couldn't load the engine." The 40 MB download was interrupted — usually a weak mobile connection or a content blocker. Press Try again on a stable connection.
- The tab reloads or crashes on a phone. Close other tabs, or shrink the photo first with Resize Image; the model needs a lot of memory.
- Part of the subject disappeared. The model guessed the wrong subject. Crop the photo tighter around what you want to keep, then run it again.
