Vimeo creators can decide whether viewers may download a file. The API only exposes downloadable variants to accounts with the right access.
If the download field is empty, a converter should not invent a file or bypass the setting. Ask the creator or use the account’s official tools.
A practical checklist
- Confirm you own the video or have explicit permission to save it.
- Use an official export or creator-enabled download when one is available.
- Choose the source quality that fits your storage and editing needs.
- Keep a record of where the file came from and when you saved it.
VidTransfer only processes a download when an authorized file is available. Recognizing a link is not the same as granting access to its media.
