Quick answer

Kapwing sends data to its servers on every edit, so uploads fail or hang on slow connections, interrupted transfers, or files the editor cannot read. Re-upload on a stable connection, using an MP4.

Most likely fix: Delete and re-upload the file

How to fix it

Try these in order — the most common fix is first.

  1. 1. Delete and re-upload the file

    1. In the Media section click the trashcan icon on the file
    2. Upload it again and keep the tab open until it finishes

    2. Upload the MP4

  3. 3. Check your connection

    1. Kapwing recommends at least 30 Mbps up and 60 Mbps down
    2. Use a wired connection or move closer to the router, and test at different times

  4. 4. Use Chrome and clear site data

    2. Click the lock icon left of the URL, choose Site Settings, then Clear data
    3. Disable ad blockers for kapwing.com
    Did this fix it?
  5. 5. Check the size limit

    1. Free workspaces: 2 GB upload limit; Pro and Business: 6 GB (from the pricing page)
    2. Compress or trim very large files before uploading
