ツールの紹介

Convert freely between s3:// URIs, virtual-hosted URLs, path-style URLs, and S3 ARNs. Pull the bucket, key, region, and version ID out of any form, and get ready-to-run aws-cli commands for copying or listing.

ツール概要

S3 exposes the same object under several addressing schemes: s3://bucket/key for the CLI, https://bucket.s3.<region>.amazonaws.com/key for virtual-hosted access, https://s3.<region>.amazonaws.com/bucket/key for legacy path-style, plus arn:aws:s3:::bucket/key for IAM. Each has slightly different rules around region segments, dualstack, and Transfer Acceleration. This tool normalizes them all: paste any form, get the others, and see warnings if the bucket name would fail S3 DNS rules.

ユースケース

  • Convert a console URL into an s3:// URI for the CLI
  • Pull the bucket and key out of a messy pre-signed URL (minus the signature)
  • Validate that a bucket name still obeys S3 DNS rules after a rename
  • Generate a quick "aws s3 cp" command from a URL you were given

よくある質問

What are virtual-hosted and path-style URLs?+
Virtual-hosted URLs put the bucket in the hostname (bucket.s3.region.amazonaws.com). Path-style URLs put it in the path (s3.region.amazonaws.com/bucket). AWS is phasing out path-style for new buckets.
Does this work on pre-signed URLs?+
Yes — the parser will extract the bucket, key, and region. The signature query parameters are surfaced for reference but not validated.
What are the S3 bucket naming rules?+
3–63 characters, lowercase letters, numbers, dots, and hyphens; must start and end with a letter or number; no adjacent dots; not an IP address. The tool flags names that violate these rules.
