Example
A sideways beach clip made vertical for Reels, keeping the person on the right
Sam filmed 20 seconds at the beach with the phone held sideways: beach.mp4, Full HD 1920 × 1080. The red and white parasol and the sea fill the left; Sam’s sister Maya stands on the right, smiling at the camera. For a vertical post: Shape “Vertical 9:16 (Shorts, Reels, TikTok)”, Keep “The right (or bottom)”, Flip “No”.
- 9:16 keeps the full height of 1080 pixels; the width becomes 1080 × 9 ÷ 16 = 607.5, rounded to 608.
- “The right” keeps pixels 1312 to 1920 across, where Maya stands. “The middle” would keep 656 to 1264, the sea between the parasol and her.
- Select Crop video. Every frame is drawn again and encoded as H.264, and the phone’s AAC sound is copied as it is.
| Shape | Kept with “The right” | Result |
|---|---|---|
| Vertical 9:16 | pixels 1312–1920 | 608 × 1080 |
| Portrait 4:5 | pixels 1056–1920 | 864 × 1080 |
| Square 1:1 | pixels 840–1920 | 1080 × 1080 |
| Widescreen 16:9 | the whole picture | 1920 × 1080 |
beach-cropped.mp4: 608 × 1080, the same length and sound, Maya in the frame. The tool never enlarges a video, so it stays 608 × 1080 rather than becoming 1080 × 1920; players scale it to the screen. A 4K clip (3840 × 2160) cropped the same way comes out at 1080 × 1920.
How it works
- Drop an MP4 or MOV onto the box.
- Choose the new shape: 9:16 for Shorts, Reels and TikTok, 1:1 for a square post, 4:5 for an Instagram portrait.
- Choose which part of the picture to keep — the middle, or the left or right side of a landscape video — and whether to mirror it.
- Select Crop video and download the MP4.
Frequently asked questions
- How long does it take?
- The picture is decoded and encoded again as H.264 at a high bit rate (up to 1920 pixels on the long side), which takes about as long as the video lasts on a typical computer and needs Chrome, Edge or Safari 16.4 or newer. The sound is copied as it is. That holds for AAC sound, which phones record; another kind (PCM in a camera MOV) is left out, and the result says so.
- Can I choose exactly where to crop?
- You choose the middle or either side, which covers most cases: a speaker on one side of a landscape shot, or the middle of a group. A crop at an exact position is not offered yet.
- What happens to a video filmed on a phone held upright?
- The crop is made to the video as it plays. A phone stores an upright clip on its side with a note to turn it; the turn is applied first, so what you see is what is cropped, and the result plays the right way up everywhere.
- Can I crop several videos at once?
- Yes. Drop up to 3 videos in one run on the free plan; each is cropped with the same shape, side and flip and comes back as its own MP4 named after the original with -cropped added.
- Why is the result not 1080 × 1920?
- The crop keeps the pixels that were there and never enlarges them. A Full HD clip (1920 × 1080) has 1080 pixels of height, so 9:16 gives 608 × 1080. A 4K clip has more to spare: 3840 × 2160 cropped to 9:16 is written at 1080 × 1920, the most this tool writes on the long side being 1920.
- Is the video uploaded, and what are the free limits?
- Nothing is uploaded. The free plan allows 3 videos of up to 150 MB per run and 5 runs a day. Pro removes these limits.
