Batch crop videos

Crop a whole set of videos to 9:16, 4:5, square or 16:9 in one go, right in your browser. No upload, no account, no watermark: your videos never leave your device.

Drop a video here or choose a file from your device MP4, MOV (including ProRes), WebM or MKV

Free, no watermark, no account. Any size of video.

How to crop several videos at once

Three steps, with nothing to install and no account to make. It works in your browser, on a computer or a phone.

Choose your videos

Drop several files on the page, or pick them from your phone's videos. MP4, MOV, WebM and MKV all work, and you can add more at any time.

Pick a shape

9:16 for TikTok and Reels, 4:5 for Instagram posts, 1:1 square or 16:9 for YouTube, and where the shape sits: left or top, centre, or right or bottom. Each video's thumbnail shows what's kept. Untick any you want to leave out.

Crop them all, then save

They're cropped one at a time, on your device, at high quality. Save them all at once, or each on its own: holiday.mov becomes holiday_ohsovideo.mp4.

Why crop videos in a batch?

Cropping one video is quick. Cropping twenty to the same shape, one at a time, means choosing each file, setting the same shape, exporting, saving and starting again. Batch crop does the repetitive part: choose the videos once, pick one shape and one position, and they're cropped one after another while you keep the page open. Then save them all together.

When a batch is the right tool

Repurposing a series. A run of landscape webinar clips, product demos or interviews, all filmed the same way, turned into 9:16 for Reels, TikTok or Shorts.
A shoot's worth of clips. Footage from one event or one camera position, cropped to 4:5 for an Instagram campaign so every post matches.
Square versions for a shop or a listing. Product videos made 1:1, so they line up neatly side by side.
Landscape versions of vertical clips. Phone videos made 16:9 for a YouTube compilation or a presentation, keeping a band across the middle of each.

When the framing differs from one video to the next, with the subject on the left in one and on the right in another, group the videos by framing (see below), or use Crop video to place the box on each one by hand.

How the shape and position work

Every ticked video gets the same shape. A shape usually cuts a video on one side only:

From a landscape video, 9:16, 4:5 and 1:1 keep the full height and cut the width, so the position chooses which part of the width is kept: left, centre or right.
From a vertical video, 16:9, 1:1 and 4:5 keep the full width and cut the height, so the position chooses the top, the centre or the bottom.

Each thumbnail shows what's kept, lit, with the rest dimmed, so you can see before cropping whether one position suits every video. A video that's already the shape you chose is left out, and says so, so nothing is made again for no reason. Videos of different sizes and orientations can share a batch: each is cropped from its own picture and keeps its own resolution.

There's no Custom shape here, because a free-form box would mean drawing a box on every video. Four fixed shapes cover what the platforms ask for, and Crop video has Custom when you need it.

Getting a mixed batch right

Group by framing. If most clips have the speaker in the centre and a few have them on the left, untick the few and crop the rest at Centre. Then tick the few, choose Left, and crop again.
Untick anything you're unsure of. Unticked videos are dimmed, marked Not selected, and left as they are.
Add more at any time by choosing more videos, and take one off the list with Remove.
For one video that needs exact placement, use Crop video, where you drag the box yourself.

An example

Say you have twelve clips from a webinar, each filmed in 1080p landscape with the speaker in the middle of the frame, and you want them for Reels. Choose all twelve, pick 9:16 and Centre, and glance down the thumbnails: the lit part of each should hold the speaker. One clip where they stepped to the side can be unticked and cropped afterwards at Left or Right. Press Crop 12 videos, keep the page open, then Save all. Each clip comes out at about 600 × 1066 pixels, ready to post.

Batch crop or one at a time?

Use batch crop when the videos are framed alike and need the same shape: it saves choosing and exporting each one separately.
Use Crop video when you need to follow a subject who isn't where the others are, place the box precisely, or crop to a custom shape.
Use both for most real sets: batch the clips that match, then crop the odd ones out on their own.

Saving the results

The videos are cropped one at a time, and the button shows how far it's got: "Cropping 2 of 3…". When they're done it becomes Save all. On a computer, each video downloads as its own file, and Chrome may ask once whether to allow several downloads. On an iPhone or iPad they come as one zip. Each row also has its own Save, and finished videos wait in your browser's private storage until you save them, so saving one never loses the others. Each is named after its original: holiday.mov becomes holiday_ohsovideo.mp4.

Quality, sound and time

Each video is saved as an MP4 at high quality, with bits for the picture you kept, so a crop looks like the original rather than a compressed copy. The sound comes too, copied as it is when it's AAC, as on most phones, and the date each video was recorded is kept.

Every video is cropped on your own device, so nothing is uploaded and there's no queue to wait in. Online batch tools need each file uploaded first and downloaded again afterwards; here the only wait is the cropping itself. It does use your device's own power, though, so a long list or 4K video takes a while. Keep the page open and in front until it's done, since phones pause a page in the background. Big batches are quickest on a computer.

On a phone

Batch crop works in Safari on an iPhone or iPad and in Chrome on Android. Choose several videos from your gallery at once, pick the shape and position, and crop. On an iPhone or iPad, Save all gives you a single zip, which the Files app opens. A phone crops each video more slowly than a computer and pauses the page if you switch away, so a short list suits a phone best, and a long one a computer.

Ready for where it's going

A crop gives your videos the shape a platform asks for. Each one also caps the size and length it takes: the size limits for each platform list them, with the size to aim for. To get a whole set under a limit, batch compress them, or compress video one at a time.

Questions about batch cropping

Are my videos uploaded to crop them?

No. Every video is cropped by your own browser, on your device, and nothing is uploaded. It works on private videos, and even offline once the page has loaded.

Can I crop each video differently?

Every ticked video gets the same shape and position. To crop some another way, untick them, crop the rest, then tick those and choose again. To place the box exactly on one video, use Crop video.

What does the position do?

A shape usually cuts a video on one side only: 9:16 from a landscape video keeps its full height and cuts the width, so the position says whether to keep the left, the middle or the right. From a tall video, 16:9 keeps the top, the middle or the bottom. Each thumbnail shows what's kept.

What happens to a video that's already the right shape?

Nothing: it says it's already that shape and it's left out, so it isn't made again for no reason.

How many videos can I crop at once?

As many as you like. They're cropped one at a time, so a long list takes a while: keep the page open until it's done. Big batches and 4K videos are quickest on a computer.

How do I save them all?

When they're done, the button becomes Save all: each video downloads on its own, or on an iPhone or iPad, all of them in one zip. Each also has its own Save link.
