Framing out distractions without losing proportions
Audo’s online video cropper crops MP4, MOV, MKV, WebM, and AVI files up to 2 GB in your browser, with the first 10 minutes free, 10 times a day, and no sign-up. Whether you need to crop an MP4 screen recording down to a single application window or tighten a wide camera shot around one presenter, you see the exact crop rectangle live on the canvas before exporting.
Because the editor holds your project non-destructively in the browser, you can adjust the crop handles, combine the crop with trims or auto captions on the same timeline, and export a single H.264 MP4 without encoding the picture twice.
Questions
How do I crop a video online?
Add your video at the top of the page, pick Any shape for a freeform rectangle or a preset aspect ratio (9:16, 1:1, 4:5, or 16:9), and press Crop video. In the editor, drag the corners and edges of the crop box directly over your video, play it back to verify the framing, and press Export to download the MP4.
What does a video cropper remove compared with trimming?
Cropping removes pixels around the outer edges of the picture—such as browser tabs on a screen recording, boom mics, or a messy background—while keeping the full duration of the clip. To cut seconds off the start, middle, or end of a recording, use Trim video instead.
Can I crop an MP4 to 9:16, 1:1, or 4:5 for social media?
Yes. Select 9:16 for Shorts, Reels, and TikTok, 1:1 for square posts, 4:5 for portrait feeds, or 16:9 for widescreen. Locking a ratio keeps the crop box at those exact proportions while you drag it over the person or product you want to keep.
Will cropping stretch faces or change the sound?
No. The area inside your crop box keeps its natural proportions without stretching or squishing, and your audio track stays in sync from start to finish. Silent clips and screen recordings without audio work the same way.
Should I use Crop video or Resize video?
Use Crop video when you want to cut away part of the image and zoom in on a region. Use Resize video when you want to keep the entire original picture visible inside a new aspect ratio with blurred or colored padding around the edges, or Horizontal to vertical video when the camera should follow an active speaker automatically.
Can I rotate or flip a video when cropping via the API?
Yes. When calling the crop_video tool through the REST API, CLI, or an AI assistant, you can pass a normalized crop rectangle along with a 90, 180, or 270 degree clockwise rotation and horizontal or vertical flips.
Is it free?
Yes. Audo processes the first 10 minutes free, 10 times a day, without an account. The whole file costs $0.01 a minute ($0.60 an hour), charged only on success. No subscription. See pricing.
