You can swap faces on iPhone in your browser by uploading a portrait as the source and the photo you want to appear in as the target. Create the swap, compare the result, then download the finished image. The practical details are choosing the right files, handling HEIC photos, and finding the saved result.
This guide uses the SwapThisFace web editor. Have both pictures available on your phone before starting. If you want a ready-made target, you can choose a photo from the face swap template collection and open it directly in the editor.
Prepare the two photos on your iPhone
Your source photo supplies the face you want in the output. Your target photo supplies the scene and starting pose. For example, use your selfie as the source and a travel portrait as the target if you want to appear in that setting.
Choose pictures with one clearly visible face each. Open the target and inspect the eyes and mouth before deciding which selfie to use. A small face inside a big landscape can look clear in the camera roll thumbnail while containing little detail when you enlarge it.
Keep the originals available. If your first result needs a different selfie, you can replace the source without starting from a screenshot of the output. Screenshots of a result include any detail already lost during the first edit, which makes them a weaker starting point for a fresh attempt.
Check the file format before uploading
The editor accepts JPG, PNG and WebP, up to 10 MB per photo. Some iPhone photos are stored in HEIF format with a HEIC file extension. Export a supported copy if the upload rejects one of those files.
For future photos, supported iPhones offer Settings → Camera → Formats → Most Compatible, which captures new photos as JPEG. Changing that setting applies to new captures. For an existing HEIF image, Apple documents exporting it to another format from an app that supports conversion. On a Mac, Photos or Preview can export it as JPEG or PNG. Apple’s format guidance
If you use a converter on your phone, inspect the exported image before uploading it. Check that the eyes and mouth are still clear and that the file is actually in the selected format. Renaming a file from .heic to .jpg does not convert its contents.
Upload your selfie in “Your face”
Open the photo face swap editor in your mobile browser. Tap “Upload your face” and choose your source portrait from the available file picker.
The picker’s labels can vary with your browser and iOS version. What matters is selecting the actual portrait file and waiting for its preview to appear in the source panel. Check the preview before continuing. It should show the person whose face you want in the result.
If you choose a picture stored in the cloud, give your phone time to retrieve it. When a file fails to load, return to your photo library or file manager, confirm that the picture opens fully, then select it again. Avoid repeatedly pressing the upload control while the first selection is still loading.
Add the target under “Your new look”
Tap “Upload a target photo” and choose the picture you want to recreate. If you arrived from the template collection, wait for that selected target to load. You can replace it with another photo using the same upload control.
For our hillside example, the target contains the landscape, coat and tilted head. The source is a separate portrait. The example gallery lets you compare those two inputs with the existing output.
Before generating, check the two preview panels together. Your face should be in the source panel and the scene you want should be in the target panel. Reversing them asks for a different result.
Create the swap and inspect it on your phone
Review the processing notice, confirm the required consent, and create the swap. Keep the result page available while processing finishes.
Use the original/result comparison to check the face against the target. Look at the eyes and mouth first, then the jaw, hairline and nearby fabric. Zoom in enough to see those details, and zoom back out to judge the whole picture.
A phone screen can make small errors hard to notice. If the image will be displayed larger elsewhere, open the saved result at a larger size before sharing. Our realistic face swap guide gives you a repeatable review process.
When the source face looks different from what you expected, try a selfie with a closer head angle. Keep the target fixed for that attempt. When the target itself has a tiny face or heavy obstruction, changing the target may give you more useful detail to work with.
Download the image and confirm where it went
Use the Download control beside the completed result. Your browser may open a preview, offer a save action, or save into its configured download location.
If the picture is not immediately in Photos, check the browser’s downloads and the Files app. A browser download and an item in your photo library can be stored in different places. Open the downloaded file to confirm you have the full image, then use the sharing or saving options your device provides to put it where you want it.
Keep the download until you have confirmed the saved copy opens. A screenshot of the result page may include browser controls and reduce the useful image area.
Fix common iPhone face swap problems
The photo is rejected
Check the actual format and size. Export HEIC into JPG, PNG or WebP and keep the file below 10 MB. If the image is a supported type, read the upload error before trying again. A service error needs a different response from a file-format error.
The create button stays unavailable
Confirm that both previews loaded and that you completed the processing confirmation. Replacing an input requires reviewing that confirmation again. Also check any account or credit message shown by the editor.
Processing is taking longer than expected
Watch the status shown on the page. If the editor says the job is still processing, check your history where available before starting another job. Repeated submissions can create separate attempts rather than speed up the first one.
The downloaded picture looks soft
Open the saved file and compare it at a similar size to the source and target. If only a messaging preview looks soft, inspect the original download first. If the face is already unclear in the downloaded output, choose a source or target with better facial detail.
iPhone face swap questions
Do I need to install a face swap app?
You can use this workflow in your iPhone browser. Open the website, select two supported image files, and save the output. The file picker and download controls come from your browser and device.
Can I swap faces between two pictures on iPhone for free?
You can try one successful guest photo swap with the current offer. Further swaps require credits from an available option. Check pricing before planning repeated variations.
Can I use a Live Photo as my source?
Use a supported still-image export for this workflow. Confirm that the chosen file is JPG, PNG or WebP and that its visible frame has the expression you want.
Can I swap every face in a group photo?
This editor expects one visible face in each input. Choose a single-person target, or prepare a crop around one person when that crop suits your intended picture.
Start with a clear pair
Choose your scene, check your selfie’s angle, and confirm the files are supported. Open the editor with those two images ready, or choose a template to have the target loaded for you.
