Photo Background Remover Apps for iPhone: How to Cut Out a Subject and Keep Transparency

There are two ways to remove a background from a photo on an iPhone. You can use the subject-lifting tools built into recent versions of iOS, or you can install a dedicated background remover app from the App Store. This guide covers both and explains how to check that the cutout is usable.

Before you start

• Check your iOS version and device. Built-in subject lifting was introduced in iOS 16 and only works on supported iPhone models, so check Apple's documentation for your device.
• Keep the original. Work on a duplicate or an exported copy so you can redo the cutout if the edges come out badly.
• Decide where the result will be used. A sticker, a product listing, a profile picture and a document layout may need different file formats, pixel dimensions or aspect ratios.
• Make sure you have free storage. Exported cutouts are saved as new files, and formats that support transparency are often larger than the original JPEG or HEIC.

Find out where the processing happens before you choose a tool. Some apps work entirely on the iPhone. Others upload the photo to a server, need an account, or need an internet connection. Read the App Privacy section on the app's App Store page and the developer's privacy policy. For Apple's built-in feature, check Apple's own privacy documentation rather than assuming. A practical check is to try the app with the network turned off: if it still removes the background, the main processing is likely local. This does not tell you what the app does with your files when it is back online, so read the policy if the photo is sensitive.

Step-by-step instructions

Use the built-in tool in Photos

• Open the photo in the Photos app.
• Touch and hold the main subject until an outline appears around it.
• Choose Copy to paste the cutout into another app, or Share to send or save it. Newer iOS versions may also offer an option to turn it into a sticker.
• If no outline appears, the subject may not be clear enough for automatic detection. In that case, try a third-party app with manual selection tools.
• Option names and their placement can differ between iOS versions, so follow what your device shows.

Some iOS versions also offer a Remove Background quick action in the Files app. To use it, touch and hold an image file. If the option appears, check that it creates a new file next to the original and does not replace it.

Use a third-party app

• Choose an app based on what it can export. It should save with transparency (usually as PNG), keep the original resolution, offer manual erase and restore tools for edges, and state clearly which features need a subscription and whether free exports carry a watermark.
• Import a copy of the photo, not the only original.
• Let the automatic detection run, then zoom in and fix the edges with any refine, erase or restore brushes the app provides.
• Choose whether to keep the background transparent or replace it with a colour or another image.
• If the app has export settings, pick a format that supports transparency, such as PNG, and the highest available resolution.
• Save the result to Files or Photos and keep the source copy until you have checked the output.

Check the output

• Transparency: some viewers show transparent areas as white or black, so a preview alone does not prove that transparency was kept. Place the image over a coloured background in an editor, a document or a presentation to confirm.
• File format: check the file extension in Files. JPEG cannot store transparency, so a cutout saved as JPEG will have a solid background. Formats such as PNG can keep it.
• Pixel dimensions: compare the exported image with the original using the info view in Photos or Files, if your iOS version shows it. A noticeably smaller result means the app or its free tier limited the export size.
• Aspect ratio: make sure the app did not crop the image to a square or another fixed shape you did not choose.
• Edges: zoom in on hair, fur, fine details, transparent objects and shadows. Automatic detection has the most trouble with these areas.
• Compression: if you exported as JPEG or another lossy format, look for blocky artefacts around the subject, especially after replacing the background.

Common problems and next steps

• The lift option does not appear in Photos: your device or iOS version may not support it, or the subject may not be separated clearly enough from the background. Update iOS if your device supports a newer version, or use a background remover app with manual selection.
• The background turns white or black after saving: either the file was saved in a format without transparency, or the app you shared it to flattened it. Export as PNG, and remember that some messaging and social apps convert images when sending.
• The edges have a halo or look jagged: refine them manually if the app allows it, and start from the highest-resolution version of the photo you have.
• The exported image is smaller than the original: look for a resolution or quality setting in the export options. Also check whether full-size export is limited to a paid plan.
• A watermark appears on the result: this is usually a free-tier limit. Check the app's pricing before you edit many photos.
• You are unsure about privacy: prefer a tool whose processing location you have confirmed, and avoid uploading personal or confidential photos to a service whose policy you have not read.

If cutouts keep failing, improve the source photo instead of switching apps again. A subject shot against a plain, contrasting background with even lighting is much easier for any tool to separate cleanly.
