Upload objects via Wrangler

Note

Wrangler only supports uploading files up to 315MB in size. To upload large files, we recommend rclone or an S3-compatible tool of your choice.

To upload a file to R2, call put and provide a name (key) for the object, as well as the path to the file via --file:

wrangler r2 object put test-bucket/dataset.csv --file=dataset.csv

Creating object "dataset.csv" in bucket "test-bucket".
Upload complete.
