A practical guide
How to turn a video into a Live Photo.
Make a short local edit on the web, then use the iPhone app for
the part that needs native Photos access.
Start by choosing the moment you want to keep, not by uploading a
whole library of clips. This website opens a supported video from
your device and lets you mark a short section for a new MP4. The
useful part of a Live Photo is usually a small gesture, a moving
subject, or a bit of atmosphere rather than a long recording, so
beginning with a one-to-five-second range keeps the decision
simple. Your original file remains in the browser while you work;
the page does not send it to a conversion server.
Before trimming, play the source once and look for a moment with a
clear beginning and ending, especially if the clip includes a
person, a gesture, or a sound you want to keep. Starting a little
before the action and ending just after it usually gives the final
MP4 room to feel natural. If the first choice is not right, use
Replace to select another local file and try again; there is no
account, queue, or uploaded copy to clean up between attempts.
Next, set the start point and motion length in the local trimmer.
MP4, MOV, and WebM source files are accepted, with short H.264
MP4 or MOV clips generally giving the most direct path. The
browser creates a separate MP4 for the selected range and keeps
the chosen audio with it. This is useful when the clip needs a
cleaner beginning, when only one reaction is worth keeping, or
when you want to make the file small enough to move through Files
on an iPhone without carrying the full recording along.
Download the trimmed MP4 when it is ready. On iPhone, Safari can
save the result to Files, but it cannot hand that local file
directly to another app or add a new item to Photos by itself.
Open All To Live after the download, choose the MP4 from Files,
and let the app create the Live Photo. That final step is where
you can choose a cover frame and save the finished result to your
photo library, using the native iPhone capabilities that a web
page does not receive.
The split between web trim and app finish is intentional. It lets
you prepare a clip without a cloud upload or a large browser
conversion download, while still using an iPhone-native workflow
for the final Live Photo. If you only need a short MP4, you can
stop after the local trim. If your goal is a Live Photo or moving
wallpaper, continue in All To Live with that downloaded file.
The same approach also makes it clear which part happens in the
browser and which part must happen on the device.
