Steps to send a large video without losing quality

  1. 01

    Export the right version

    Check the resolution, sound, captions, format, and filename.

  2. 02

    Play it on your device

    Check the start, middle, and end before uploading.

  3. 03

    Choose the original file

    Add it to TransferSize and start the upload.

  4. 04

    Choose whether to allow preview

    A browser preview is handy, but some video formats will not play in every browser.

  5. 05

    Tell the recipient the format

    Include the file size, format, and any app they need to open it.

What the recipient sees

The recipient opens the transfer link in a browser, enters the password if one was set, previews supported files when enabled, and downloads without creating an account.

Good to know

A few things that matter

The upload does not shrink the video

TransferSize delivers the file you selected. A browser preview is separate from the original download.

A preview can still fail

The upload may be fine even when the browser cannot play that codec. Download the original and use a compatible player.

Live Relay is different

Live Relay protects an existing HLS stream. It does not turn an uploaded video into a stream.

Questions

Questions people ask

Will TransferSize lower the quality?
