Updated 2026-09-24 · 5 min read

Crop video online — set crop box pixels and download MP4 locally. Video cropper for “crop video to any size” when you know numbers — not freeform drag like Kapwing/Clideo, not one-click “crop video for social media” 9:16 presets. Cut video frame online? Use frame extractor for a PNG still; cropper exports reframed MP4. 25 MB cap.

What is Crop video online free and who is it for?

Crop video online free — pixel crop box (25 MB, wasm). Crop video for social media by entering 9:16 pixels — not Canva/Kapwing drag presets; PNG still → frame extractor.

Searches for “video cropper” usually mean a file already on your phone or laptop — not a YouTube/TikTok URL. This guide points to the upload workbench and honest limits (25 MB, browser wasm) versus cloud tools with huge caps.

Targets “crop video online,” “crop video for free,” “crop video to any size,” and “crop video for social media” with honest numeric UI vs preset-heavy competitors.

How to use Crop video online free on Peraspera Tools (step by step)

Follow the same four-step pattern on the live tool page — optimized for mobile and desktop browsers.

  • 1. Upload — Video up to 25 MB.
  • 2. Crop box — Width, height, X, Y in pixels.
  • 3. Crop — Wasm crop filter.
  • 4. Download — Cropped MP4.

Crop video with pixel box values

These utilities run ffmpeg.wasm in your tab — Peraspera does not store your upload on our servers. First visit downloads the encoder; keep the tab open until export completes.

Maximum upload size is 25 MB per file. That is smaller than many cloud compressors advertising multi-gigabyte queues — by design for privacy and mobile stability.

  • Choose a file from your device (MP4/WebM/MOV where the browser can decode).
  • Adjust any fields shown on the workbench (times, crop pixels, output format, etc.).
  • Click Process & download and check your Downloads folder.
  • For YouTube or TikTok URLs, use the link-based downloader or MP3 pages instead of upload tools.
