Nearby / same Wi-Fi

What is this?

Nearby / same Wi-Fi

Use this when: Both devices are on the same local Wi-Fi or LAN and you want the file-data path to stay local.

How it works: E-Pen disables STUN/TURN for the transfer peer and uses local ICE candidates. Open the generated Nearby link or QR on the receiver.

Good to know: Internet is still needed for public rendezvous signaling, and guest/corporate Wi-Fi isolation can block local peer connections.

Keep file data on the same Wi-Fi/LAN. Both browsers still need internet to connect.

Resume checkpoints

What is this?

Resume checkpoints

Use this when: You are sending large files or unstable networks may interrupt the transfer.

How it works: E-Pen stores local encrypted progress checkpoints so verified files can be reused after an interruption instead of starting the whole session from zero.

Good to know: Automatic live reconnect still works even when checkpoints are off.

Keep encrypted local checkpoints for interrupted sessions. Live network reconnection stays automatic even when this is off.

Allow receiver file selection

What is this?

Selective receive

Use this when: You are sending several files but the receiver may only need some of them.

How it works: Before accepting, the receiver can uncheck files. E-Pen then streams only the selected items.

When enabled, the receiver can choose only the files they want before accepting.

Game / huge folder mode

What is this?

Game / huge folder mode

Use this when: You are moving very large folders, game files, archives, videos, or already-compressed content.

How it works: Compression is disabled so the browser spends less CPU time recompressing data that usually will not shrink much.

Good to know: This can improve responsiveness and throughput on large transfers, but it may use more network bandwidth for compressible files.

Disables compression to reduce CPU load for game folders, archives, media libraries, and very large transfers.

Privacy & session limits

The password stays in the invitation link fragment, not the server request. Waiting rooms expire after 10 minutes; an active transfer has no fixed time limit.
