SessionTransfer – File Transfer for AWS Session Manager

Transfer files to/from EC2 via Session Manager terminal. Drag & drop upload, chunked download, in the AWS Console.

SessionTransfer adds a floating panel to the AWS Management Console that lets you upload and download files through Session Manager — no S3, no SSH, no extra tools required. 【UPLOAD (Local → EC2)】 • Drag & drop or click to select a file • Automatic gzip compression (when beneficial) • Configurable chunk size (default 32 KB) • One-click "Auto-send to terminal" — commands are pasted directly into the Session Manager terminal • Progress bar with chunk tracking 【DOWNLOAD (EC2 → Local)】 • Enter a file path on the EC2 instance • Extension sends base64/gzip commands to the terminal automatically • Copy terminal output → click "Paste & Next" → repeat until done • File auto-downloads when all chunks are received 【HOW IT WORKS】 Files are split into Base64-encoded chunks and sent as shell commands via xterm.js paste events. No additional IAM permissions, S3 buckets, or open ports are needed — if you can access Session Manager, you can transfer files. 【SUPPORTED TERMINALS】 • AWS Systems Manager Session Manager • EC2 Instance Connect (EIC) browser-based terminal 【KEY FEATURES】 • Works with existing Session Manager or EIC access — no extra permissions • Gzip compression — automatic when it reduces transfer size • Chunk size control — avoid terminal deadlocks with large pastes • Floating panel — draggable, minimizable, works on any AWS Console page • Upload & Download — bidirectional file transfer 【PRIVACY】 • This extension only activates on *.console.aws.amazon.com • No data is collected, stored, or transmitted to any external server • All processing happens locally in your browser This extension is not an official AWS product.
