S3 URI Parser & Builder

Convert between every way of writing an Amazon S3 location. Paste an s3:// URI, an HTTPS URL or an ARN to break it apart - or fill in the fields to build all four forms. Nothing leaves your browser.

Paste an S3 URI, HTTPS URL or ARN

Recognises s3://bucket/key, https://bucket.s3.region.amazonaws.com/key, https://s3.region.amazonaws.com/bucket/key and arn:aws:s3:::bucket/key.

The forms explained

s3:// URI - what the AWS CLI and SDKs use: s3://bucket/key. No region.
Virtual-hosted URL - the modern HTTPS form with the bucket in the hostname: https://bucket.s3.region.amazonaws.com/key.
Path-style URL - the older form with the bucket in the path: https://s3.region.amazonaws.com/bucket/key. AWS is retiring it, but S3-compatible providers still use it widely.
ARN - how IAM policies name the object: arn:aws:s3:::bucket/key. No region or account for S3.

Using it with FTPie

FTPie browses Amazon S3 and every S3-compatible bucket in a normal dual-pane file manager, so you never have to hand-write these paths - but when a script, log or IAM policy hands you one, this tool tells you exactly which bucket and key it points at. Need a scoped key? Try the S3 IAM Policy Generator.
