# snapchat_upload_media

> Upload base64 image/video bytes to a previously created media object. A write tool that previews before it changes anything, one of 41 Snapchat Ads tools…

[Documentation](https://www.getmcpads.com/docs) / [Sources](https://www.getmcpads.com/docs/sources) / [Snapchat Ads](https://www.getmcpads.com/docs/sources/snapchat-ads)

Upload base64 image/video bytes to a previously created media object. Maximum 10 MiB decoded. No external URL fetching. Preview does not send bytes; confirm true uploads after ownership verification.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
