How it works

  1. 01

    Choose a file for Resize Video. It accepts MP4, MOV, WEBM, MKV, M4V, AVI, WMV, FLV, MPEG, MPG, MPE, 3GP, 3G2, TS. Most files stay in this tab.

  2. 02

    Set the options on the workbench — preview, crop or timeline when this tool has one — then press Run.

  3. 03

    Download the result. It is also saved in your tray so the next tool can pick it up without another upload.

About this tool

Choose a preset — 1080p, 720p, 480p, a 1080×1080 square or 1080×1920 vertical — or type a custom width and height. Contain keeps the whole picture and adds bars, Cover fills the frame and trims the overflow, Fill stretches. Presets adapt to portrait sources, so 720p on a vertical clip gives 720×1280. Downscaling is also the fastest way to make a file smaller without touching quality settings.

Questions

What can I open in Resize Video?
Resize Video accepts MP4, MOV, WEBM, MKV, M4V, AVI, WMV, FLV, MPEG, MPG, MPE, 3GP, 3G2, TS. Older video containers such as AVI, WMV, FLV, MPEG and 3GP are decoded by the server encoder.
Does Resize Video upload my file?
Most MP4, WebM, images and PDF stay in this tab. Instagram/TikTok crops, DVD, GIF, iPhone presets, stabilize, hard containers (AVI, WMV, HEVC) and a failed local encode go to the server encoder. The file is processed and discarded — we do not keep a copy.
How large can the file be?
Free: 500 MB and 8 exports a day. Plus (waitlist) raises the daily cap. A pasted public file URL is also accepted.
