How to remove a background from a photo for free

Product listings, profile pictures, stickers, slides: most of the time you want the subject and not the room it was photographed in. You no longer need Photoshop, a pen tool or a paid service for this. A segmentation model small enough to run in a browser finds the subject automatically, and several operating systems now ship a one-click version of the same idea.

This guide covers the whole job: getting a clean cut-out, putting it on a new background, making the file the right size for where it goes, and fixing the results that come out wrong.

Pick the right method first

There are three realistic routes, and the best one depends on what you do next.

• A built-in tool on your device. Fine for a single quick sticker or a slide. Limited control over output size and format.
• A browser tool. Works on any device, handles a batch of photos, gives you a full-resolution PNG and keeps the files on your device.
• An image editor with masks. Still the right tool for hair against a busy background, glass, or anything going to print at large size. Usually you start from an automatic cut-out and only fix the edges.

Built-in options worth knowing

• iPhone and iPad: in Photos, touch and hold the subject until it lifts out, then choose Copy or Share. You get a transparent cut-out you can paste into a message, a note or another app.
• Mac: in Finder, right-click an image and use Quick Actions > Remove Background. A new file with a transparent background is saved next to the original.
• Windows 11: the current version of Paint has a Remove background button that works on the whole picture or a selected area.
• Word and PowerPoint: select a picture and use Remove Background on the Picture Format tab. Handy when the result only needs to live inside that document.
• Android: some gallery apps, Samsung's for example, let you long-press the subject to copy it out. Availability depends on the phone and its version.

If one of these does the job, use it. The browser route makes sense for batches, a full-resolution PNG file, or when the built-in edge is poor.

Remove the background in the browser

1. Open Remove background and drop one or more JPG, PNG or WebP photos, up to 30 MB each. iPhone photos in HEIC format need converting first with HEIC to JPG.
2. The first run downloads the model, about 45 MB, with a progress bar. It is then kept in the browser cache, so later visits start straight away.
3. Each photo is processed in a few seconds on a recent laptop; phones are slower. A small preview on a checkerboard shows the result.
4. Download each PNG, or all of them as one ZIP.

Two details matter for quality. The output keeps your original resolution: only the mask is calculated at 1024 by 1024 pixels, then scaled back up to the photo's size. And the mask is soft, so hair and fur fade out instead of being cut with a hard line. That looks natural, but faint fringes can keep a trace of the old background colour.

The neural network runs on your own device. The photos are not uploaded, which matters for pictures of people, children or unreleased products.

Shoot for a clean cut-out

The photo matters more than the tool. Five minutes of preparation saves an hour of edge repair.

• Contrast. A dark product on a light wall, a person in front of a plain door. A white mug on a white table gives a blurry or missing edge with any tool.
• One clear subject. The model looks for the main object. Two people standing apart, or a product surrounded by props, forces it to guess.
• Fill the frame. The image is squeezed to a square for analysis, so a small subject in a wide shot gets very few pixels. Crop close first with Crop image, leaving a little margin around the subject.
• Even light. Hard shadows under a product are often treated as part of it. Shoot near a window on a cloudy day, or bounce light off a white wall.
• Sharp focus. The mask cannot be sharper than the photo.

Put the subject on a new background

A transparent PNG is the raw material. What you do with it depends on where it goes.

White background for a marketplace

Most marketplaces want a plain white or light background, and many prefer JPG. Run the cut-out through PNG to JPG, keep the background colour on white and the quality at the default 85%. Transparent areas are filled with white, and the soft edge is blended into it, so there is no grey halo.

For a catalogue, shoot all items from the same distance and crop them to the same ratio, for example 1:1, so the products appear at a similar scale in the grid.

Coloured background for a profile picture or card

Use the same tool and pick any colour in the background picker. Choose the exact colour of the place the image will sit on, such as a slide background or a brand colour. A cut-out flattened onto white and then placed on a dark banner shows a pale outline; flattened onto the right colour, it blends in.

Keep the transparency

For a logo-style overlay, a sticker or a design file, keep the PNG. If the file is heavy for a website, PNG to WebP keeps the transparency and is usually much smaller.

Make the file the right size

Transparent PNGs are large: often two to five times the size of the original JPG, because PNG compression is lossless and the alpha channel adds data. A 4000-pixel cut-out shown at 800 pixels is wasted bytes.

• Website or online shop: resize to 1200 to 2000 px on the long side with Resize image. Resizing keeps the transparency of PNG and WebP.
• Profile picture: crop to 1:1 first, then resize to around 800 by 800 px; that is plenty for any avatar.
• Slides and documents: 1600 px on the long side covers full-screen display.
• Print: keep the full resolution and the PNG.

Resize after removing the background, not before. The mask is always calculated at the same internal size, so starting from a larger photo gives you more detail along the edge.

Troubleshooting

• Part of the subject is missing. Usually low contrast: dark hair against a dark wall, or a white shirt against a white sky. Reshoot with more contrast, or touch up the gap in an editor.
• Some background is left behind. Furniture or a second object touching the subject was treated as part of it. Crop tighter and run it again.
• A coloured fringe around the edge. The soft mask keeps a hint of the old background. Flatten onto a background colour similar to the original, or erase a pixel or two along the edge in an editor.
• Glass, smoke, water, a veil. Transparent and reflective materials show the old background through themselves. No automatic mask represents that well; expect manual work.
• The tab crashes or the result never arrives on a phone. A large photo needs several hundred megabytes of memory during processing. Resize it to around 2000 px first, or use a computer.

Checklist

1. Shoot with contrast, even light and one subject that fills the frame.
2. Try the built-in option on your device if you need a single quick cut-out.
3. Crop close, then remove the background in the browser.
4. Check the edge at 100% zoom, especially hair and dark areas.
5. Flatten onto white or a matching colour as JPG, or keep transparency as PNG or WebP.
6. Resize to the size the image will actually be shown at.
7. Keep the original photo in case you need a better cut-out later.
