Resize video.
Fill, fit or blur. Never stretched.
Turn one clip into 9:16 for TikTok and Reels, 4:5 for the Instagram feed, a square or 16:9 for YouTube.
Free: use an app on your phone or Mac, Clipchamp in a browser, or FFmpeg. Studio is the paid route, with fill, fit and blur on any canvas.
- iPhone
- In Photos, open the video, tap Edit, then Crop. Tap the aspect ratio button, pick 9:16 or Square, then Done. This cuts the edges. For fewer pixels, iMovie's Share, Options lets you pick 720p before Save Video.
- Android
- In Google Photos, open the video and tap Crop, then Aspect ratio, and pick a shape. Tap Save to keep a copy. This cuts the edges.
Resize a video in Studio
Studio runs in a desktop browser, on plans from $19 a month. It exports MP4 or WebM up to 4K with no watermark, and each project's first export is included.
Fill: the clip covers every frame and the sides are cut. The outlines show what each shape keeps.

- In Clipchamp, Microsoft's editor, free with a Microsoft account: click the size button above the stage and pick 9:16, 1:1, 4:5 or 16:9. The clip keeps black bars until you select it and click the fill button. The free plan exports up to 1080p.
- FFmpeg
Fit a wide clip into 9:16 with bars. Fill and blur commands are in fill, fit or blur.

Which resize do you need?Shape, pixels or megabytes.

16:9to9:16
Change the aspect ratio
For TikTok, Reels or a square post. The frame changes shape, so the edges get cut, padded or blurred.
Fill, fit or blur - Pixels
4Kto1080p
Change the resolution
Same shape, fewer or more pixels. Going down keeps the picture sharp. Going up adds no detail.
Export sizes - Megabytes

Change the file size
For a chat app, email or a slow upload. A lower bitrate makes the file smaller, often with a smaller resolution too.

How to resize a video.Four steps in Studio.
The canvas sets the size of the video. The clip sits inside it, and you choose what happens at the edges.
- 1080 × 1920
1Set the canvas
Create a Studio project and click an empty part of the canvas. Type the size under Canvas, or press swap to turn 1080 × 1920 into 1920 × 1080.

2Add the clip
Upload the video in the media panel and drag it onto the timeline. Studio fits it inside the canvas, centered, with nothing cut.
Upload
3Fill or blur the edges
To fill, turn off Keep aspect ratio and set the clip to the canvas size. Studio crops the clip to its new box and never stretches it. To blur, duplicate it with Cmd or Ctrl + D, stretch the lower copy and add Effects, Blur.

Resize a video to a file size.Pick the megabytes, get the bitrate.
A Gmail attachment can be 25 MB, and chat apps set their own limits. Studio has no file size setting, so a 720p export at 30 frames a second is the quick way to a smaller file there. For an exact limit, run this FFmpeg command.
Sound is kept at 128 kbps. The command runs FFmpeg twice so the file lands just under the size. On Windows, write NUL instead of /dev/null.
Video bitrate
1,596kbps
Scaled to 720p, the largest size this bitrate usually looks clean at.

Resizing a video
For free, crop it to a new shape in Photos on iPhone or Google Photos on Android, export a smaller size from QuickTime Player on a Mac, or pick a new shape in Clipchamp in a browser. In Studio, set the canvas to the size you need, such as 1080 × 1920 for TikTok or 1920 × 1080 for YouTube. Upload the clip and drag it onto the timeline, where it fits inside the canvas. Fill or blur the edges if you don't want bars, then export as MP4 or WebM.
Reels and Stories are 9:16, exported at 1080 × 1920. Feed posts can be 4:5, 1080 × 1350, or square, 1080 × 1080. Set the Studio canvas to that size, fit, fill or blur the clip, and export.
Fit it. The whole picture shows inside the new frame and the empty space becomes bars. For a full frame without bars, put the clip over a blurred copy of itself. Studio doesn't stretch clips: a clip in a box of another shape fills it and loses its edges instead.
Making a video smaller keeps it sharp, apart from the small loss of any new encode. Making it bigger adds pixels but no detail, so a 720p clip exported at 4K looks like 720p in a larger file. Fill also enlarges the part it keeps, so start from the biggest source you have.
Lower the bitrate, and the resolution with it. In Studio, export at 720p and 30 or 24 frames a second. For an exact limit, such as 25 MB for a Gmail attachment, use the file size calculator on this page and run its FFmpeg command.
Resizing changes the frame or the pixel count and keeps the whole picture. Cropping cuts part of the picture away. Fill is a crop, while fit and blur are resizes. Our crop video page covers choosing what stays.
To keep the shape and set the height, run ffmpeg -i input.mp4 -vf scale=-2:720 -c:a copy output.mp4, where -2 keeps the width even. For a new shape, use the fill, fit and blur commands in the section above.
No. Studio's framing stays where you set it. If the subject moves, press S to split the clip and give each piece its own Crop focus. Studio doesn't paint new picture past the edges of a video; blur fills them with a soft copy instead.
Plans start at $19 a month with 500 credits. A project's first export is free and each one after that is 10 credits. Every paid plan includes commercial use and exports without a watermark.
