How to Make YouTube Shorts From Long Videos (Free, No Watermark)
One long video can become five, ten, even twenty short clips. Here's the simplest way to turn a long YouTube video, podcast or stream into ready-to-post Shorts, TikToks and Reels — free, right in your browser, with captions burned in and no watermark.
Why turn long videos into Shorts?
Short-form video is where new audiences find you. A single long upload already contains your best moments — the punchlines, the hot takes, the "wait, what?" reactions. Clipping those moments into vertical Shorts lets one piece of content work ten times as hard, and each clip is a fresh chance to go viral and send viewers back to your main channel.
The problem is time. Manually scrubbing a 40-minute video, cutting clips, reframing them to 9:16 and typing captions takes hours. That's exactly what a good shorts maker automates.
What you'll need
- A long video file (MP4, MOV or WebM) — a talking video, podcast, stream or vlog works best.
- A web browser on a laptop or desktop (nothing to install).
- About 2 minutes. That's it — no account, no card, no watermark.
Step by step: long video → Shorts
Open a free shorts maker
Go to Shortify. It runs 100% in your browser, so your video never uploads to a server — it stays on your device.
Drop in your long video
Choose your file or drag it onto the page. If it's a long episode, use the timeline to trim to the section you want clips from.
Let the AI find the best moments
Shortify transcribes the audio and scores every segment — laughter, emphasis, questions and hook words — then picks the strongest moments automatically. You choose how many Shorts you want and how long they should be.
Pick a caption style
Captions are what make Shorts watchable with the sound off. Choose from 60+ styles — clean white, karaoke word-by-word, neon, boxed, animated pops and more. Captions are synced word-by-word to the voice and burned into the video.
Download your Shorts
Each clip is cut to vertical 9:16, captioned and ready to post. Download them one by one or grab all of them as a zip. No watermark, ever.

- Start on a hook. The first 1–2 seconds decide everything. Trim each clip so it opens on the most surprising line, not the setup.
- Always use captions. Most people watch on mute. Word-by-word captions dramatically boost watch time — pick a bold, high-contrast style.
- Keep it tight. 15–40 seconds usually outperforms 60. Cut dead air.
- Post consistently. One long video = 5–10 Shorts = a week of daily posts. Consistency beats perfection.
- End on a loop or a question. A clip that makes people rewatch or comment gets pushed to more feeds.
Is it really free with no watermark?
Yes. Shortify runs in your browser using your own device's power, so there's no server cost to pass on to you. Every caption style, AI best-moment picking and unlimited exports are free, with no watermark and no login. Your video never leaves your computer.
Frequently asked questions
Do I need to install anything?
No. Shortify runs entirely in your web browser. There's nothing to download and no account to create.
Will there be a watermark on my Shorts?
No watermark. Your downloaded clips are clean and ready to post to YouTube Shorts, TikTok or Instagram Reels.
Can I use it for TikTok and Reels too?
Yes — the clips are standard vertical 9:16 MP4 files, so they work on YouTube Shorts, TikTok and Instagram Reels.
How long can my video be?
Because processing happens on your device, short and medium clips are fastest. For very long episodes, use the built-in trimmer to select the part you want to clip from.
