Why S3Toolbox

Built like a power tool, not a web upload box.

Dual-pane workflow

Two panels side by side, Total Commander style. Copy and move between any two locations — local, S3, SFTP — without leaving the window.

Real transfer queue

Every upload, download, copy and delete is queued with live progress, speed and ETA. Pause, resume, reorder, and cap concurrency.

Sync, not just copy

Preview exactly what will be copied, updated, or deleted before it runs. Mirror or update modes, checksum-aware, powered by rclone under the hood.

Efficient transfers

Copy within the same S3 service and the data moves server-side — it never travels through your machine. Between different locations, files stream straight through; nothing is written to your disk.

Bandwidth control

Set upload and download speed limits and the number of parallel transfers so a big sync never saturates your connection.

Light & dark themes

A clean, native Windows interface that follows your taste, not your OS vendor’s.
