How to clip videos on your phone

Yes. A phone can do every step of clipping: find the moment, cut it, make it vertical, caption it and post it. You need the video (your own, or one you have permission to clip), an app to edit it, and the app you post to. Here's what does what:

Whose video it is matters as much as how you cut it. Your own videos are yours to clip; anyone else's needs their permission, like a clipping campaign gives. See is clipping legal? before you post someone else's.

The slowest part of clipping, on any screen, is finding what's worth posting. On a phone, let the viewers point the way:

• YouTube's Most replayed graph. In the YouTube app, tap the video to bring up the progress bar and start seeking: a graph shows up above the bar, and its peaks are the parts people rewatch most. It doesn't show on every video (one that's too new or has too few views, for example). To land on the exact second, slide up from the red dot for a row of thumbnails.
• Chapters and comments. Chapters split a long video by topic, and comments with times in them are the moments viewers remember.
• The Twitch app's Clip button, at the top of the stream (tap the video if you don't see it). It saves up to 60 seconds of a live stream or a past broadcast. You can trim and title it on your phone, but changing its portrait layout needs a computer. Posting one to TikTok is in how to post Twitch clips on TikTok.

Write each moment's start and end time in your notes as you go, then cut them all in one pass. More signals to look for are in how to find the best moments to clip.

What about YouTube's Clip button? YouTube's help still describes it (below Subscribe, slide the options to the right, tap Clip and pick 5 to 60 seconds), but in April 2026 YouTube said sharing at a timestamp was replacing new clips, and that clips already made stay viewable. Either way, a YouTube clip was a link that plays on YouTube, not a file you can post. To keep a moment now, tap Share and turn on the time toggle before you copy the link.

The Photos app does both, with nothing to install. To cut the clip out of a longer video:

1. Open Photos and tap the video.
2. Tap the Edit button.
3. Move the sliders at both ends of the timeline to where the clip starts and stops.
4. Tap Done, then Save Video as New Clip. That keeps the whole video and adds the clip to your library; Save Video keeps only the trimmed part.

To make it 9:16, open the clip, tap Edit, then Crop. Tap the aspect ratio button and choose 9:16, drag the corners (or pinch) until the frame holds the person talking, and tap Done. Changed your mind? Open it, tap Edit, then Revert. These are the steps in Apple's iPhone User Guide for iOS 27; names can differ a little on older versions.

A crop stays where you put it. That's fine for one person sitting still; if they move, or two people take turns, part of the clip ends up off frame, and you'd need to split it and crop each part. For captions from speech, use an editor app (below) or the app you post to.

On Android, the Google Photos app trims and crops:

1. Open the Google Photos app and open the video.
2. To trim it, touch and hold, then drag the trim handles to the part you want to keep.
3. To crop it, tap Crop, then Aspect ratio to choose a shape. Google's help names a square as its example and doesn't list the others, so look for 9:16 in your version's list.
4. At the top, tap Save. Google Photos saves a copy of the video with your edits.

Phone footage that shakes can be steadied too: tap Auto, then Stabilize. Not every phone gets every tool: Google says crop, straighten and filters need at least 1 GB of RAM and Android 6.0 or later, and that non-Pixel phones running Android 9 don't have video editing at all.

For captions generated from speech, text on screen and a frame that follows the speaker, use an editor app. CapCut's own pages give these steps for its phone app:

1. Start a project. Tap New project and pick the video.
2. Cut it down. Tap the clip on the timeline to open its editing tools, and trim it to the moment.
3. Frame it. Auto Reframe, under Adjust, keeps the subject in frame for you, but CapCut lists it as a CapCut Pro feature on mobile. Without Pro, you move the video yourself.
4. Caption it. Tap Captions in the bottom menu, choose the language spoken and a template, and start generating. Then read every line and fix what it misheard before you export.
5. Export at 1080p. Tap the resolution label next to Export at the top right, choose 1080P, then tap Export.

Watch for the Pro mark on anything you use: CapCut asks you to upgrade when you export a project with a Pro feature in it. The full routine, on desktop and mobile side by side, is in how to make clips in CapCut.

You can also caption in the app you post to, as you upload:

• TikTok: after you record or upload, turn on auto captions on the editing page, then fix the text once it's generated.
• Instagram Reels: before you share, tap More options and turn on Enable closed captions, or add the Captions sticker. Meta's free Edits app also generates captions you can style and edit word by word.
• YouTube Shorts: automatic captions are added where they're available, and can be fixed in YouTube Studio.

The catch: an app's captions live in that app, in its style, and viewers can turn them off. Captions burned into the video look the same everywhere, with the sound off, which is why clip pages use them. Posting the same clip to three apps? Burn the captions in once and upload that file to each. The details are in how to add captions on TikTok, Reels and Shorts.

Social Media Today reported in January 2025 that TikTok added scheduling to its separate TikTok Studio app, but TikTok's own help pages describe scheduling on a computer. The steps for each app are in how to schedule TikToks, Reels and Shorts.

• Upload your own file to each app, not a copy saved from another app. Why, and how to post one clip everywhere, is in how to cross-post short videos.
• Write a caption that says what happens and names the creator, with any tags a campaign asks for.

One clip on a phone takes a few minutes. Ten clips from one video is the same routine ten times: scrub for the moment, trim, crop, caption, fix the captions on a small screen, export, post. And a crop that stays put means a two-person podcast has to be split and reframed by hand every time the speaker changes.

That's fine for a clip a day of your own videos. For a clipper posting several a day, maybe across several accounts, the finding, cutting and framing is the work worth handing off. How AI clipping tools do it is in how to clip videos with AI, and more ways to speed up are in how to clip faster.

Clyper is a web app, so there's nothing to install: open it in your phone's browser, sign in with Google or with a one-time link sent by email, and start a video one of two ways:

• Paste a YouTube link: any public or unlisted video from 1 minute to 4 hours long. Copy it with Share in the YouTube app.
• Or upload a video from your phone: MP4, MOV, WebM or MKV, up to 4 GB. Keep the tab open until the upload finishes.

Choose how many clips you want (or leave it on Auto) and a caption style. Clyper finds the moments that stand on their own, cuts each on whole sentences, frames it 9:16 on whoever's talking and captions every word: up to 30 clips from one video. On your phone you can play each clip, open it in the editor to trim it, fix a caption's words or change its style, and tap Download for a 1080 × 1920 MP4 with no watermark. On an iPhone, a file you download in Safari goes to the Downloads folder in the Files app. Clips are kept for a limited time, and each one shows the date to download it by.

Then post them from TikTok, Instagram and YouTube as above: Clyper doesn't post or schedule for you. More on clipping from a link in how to clip a YouTube video and YouTube to Shorts.
