Background removal
How to remove a background on iPhone
Open the photo in the Photos app, touch and hold the subject until an outline appears, then tap Copy, Share or Add Sticker. The subject comes away from its background, ready to paste into a message, a note or another app. Apple’s guide says it works in Safari and Quick Look too.

How to lift a subject from a photo on iPhone
- Open the photo in full screen in the Photos app, or pause a video on any frame.
- Touch and hold the subject.
- When an outline appears around the subject, tap Copy or Copy Subject, then paste it into an email, a message or a note.
- Or tap Share to send it with AirDrop, Mail or another app, or tap Add Sticker to save it as a sticker for Messages and Markup.
- To place it straight into a document, keep holding the subject, open the other app with another finger and drag the subject in.
Apple’s iPhone User Guide says lifting a subject also works in Safari, Quick Look and other apps.
On a Mac: remove a background in Preview
- Open the image in the Preview app.
- Click the Remove Background button.
- If Preview asks whether to convert the file to PNG, click Convert. To keep the original as it is, click Cancel, choose File > Duplicate and remove the background from the copy.
- To undo the removal, choose Edit > Undo.
Limits of the iPhone method
- The iPhone decides what the subject is. Apple’s steps include no way to adjust the outline, so a part it misses stays missed.
- It needs a clear subject: a person, a pet or an object that stands out from what is behind it. A busy or similar-colored background is harder.
- What you get is a copy, a share or a sticker. Where you paste or save it decides whether the transparent area survives: an app that only takes JPEG fills it in.
| What you get | Adjusting the outline | Transparency | |
|---|---|---|---|
| iPhone: Photos, Safari and Quick Look | A copy, a share or a sticker | None in Apple’s steps | Kept only where you paste it: an app that takes only JPEG fills the area in |
| Mac: Preview | The open file, converted to PNG, or a duplicate of it | None in Apple’s steps; Edit > Undo reverses the removal | Kept in the PNG |
| DreamBench AI background remover | A PNG to download, on transparency or plain white | No brush: a matting model sets how see-through each edge pixel is | Kept in the PNG, up to 2048 pixels on the long edge |
When the outline skips part of the subject, there is nothing to adjust on the iPhone: try a photo in which the subject stands out more, or use the AI background remover in the browser on the same iPhone, which estimates how see-through each edge pixel is and returns a PNG you can check at full size.
When DreamBench is the better choice, and when it isn’t
For a sticker or a cutout pasted into a message, the iPhone is quicker: it is built into Photos and costs nothing extra.
Use the AI background remover when you need a file: a PNG on transparency or plain white, made by a matting model that keeps hair and fine edges. It runs in the browser on an iPhone too. A cutout uses 7 credits, and the result can open in the composer as a reference for a video.
Questions
Can I remove a background on iPhone without an app?
Yes. Lifting a subject is built into the Photos app, and Apple’s iPhone User Guide says it also works in Safari and Quick Look. You don’t need to install anything.
Can I lift a subject from a video on iPhone?
Yes, from a paused frame. Apple’s guide says to pause the video on any frame, then touch and hold the subject.
How do I make a sticker from a photo on iPhone?
Touch and hold the subject until an outline appears, then tap Add Sticker. The sticker is saved for Messages, Markup and other places that take stickers.
How do I remove a background on a Mac?
Open the image in Preview and click the Remove Background button. If Preview asks to convert the file to PNG, convert it, or duplicate the file first to keep the original.
Why won’t my iPhone lift the subject, or why does part of the background come with it?
Your iPhone won’t lift the subject when it can’t tell the subject from what is behind it: Apple’s steps need a clear subject, such as a person, a pet or an object that stands out, and they give you no way to adjust the outline, so a part it misses or adds stays that way. Try another photo with more contrast, or make the cutout with the AI background remover, which runs in the browser on an iPhone and keeps a soft edge for hair.
Does lifting a subject work on an older iPhone?
Lifting a subject may work on an older iPhone: Apple’s iPhone User Guide, in the iOS 27 edition read for this page, describes the steps without listing which models have them, so try it: open a photo, touch and hold the subject and see whether an outline appears. If none does, the AI background remover runs in the browser on any iPhone, with nothing to install, and shows its price in credits before you run it.
