How it works

  1. File is sliced into 10 MB chunks

    The browser splits the video using File.slice() — no server involvement and no temporary storage needed.

  2. Each chunk is uploaded with identity headers

    Every request carries X-Unique-Upload-Id (shared UUID) and Content-Range: bytes start-end/total so Cloudinary can track and order the pieces.

  3. Failed chunks are retried automatically

    Network blips won't abort the upload. Each chunk retries up to 3 times with exponential back-off before the upload fails.

  4. Cloudinary assembles and hosts the video

    Once the final chunk arrives, Cloudinary stitches the pieces into a single asset and returns a global CDN URL for instant streaming.
