Do my files pass through or get saved on any server?

No. Nearsend is strictly a peer-to-peer (P2P) platform. The signaling server is only used to exchange temporary session tokens and WebRTC handshake coordinates. Once connected, your files, text, and clipboard stream directly between your devices via WebRTC DataChannels in 64KB encrypted chunks.

How does the Voice Pairing work securely?

When you generate a voice pairing phrase, the host device creates an ephemeral 3-minute token. When spoken on the guest device, browser speech recognition converts the acoustic phrase into the token. The server validates the match and immediately triggers an explicit confirmation prompt on the host device before any connection is allowed.

Does Nearsend work across different operating systems?

Yes! Nearsend works seamlessly across any modern web browser — Windows, macOS, Linux, Android, iOS, iPadOS, and ChromeOS. No native apps or software installations are required.

Is there a file size limit on Nearsend?

Because transfers stream directly via WebRTC without hitting a central server memory limit, you can send files ranging from kilobytes to multi-gigabyte videos. Nearsend incorporates backpressure flow control to ensure smooth transmission without exhausting device RAM.

Why Large File Transfers Are Getting More Common

October 4, 2026

"Large file" means something different today than it did a decade ago, and it's worth understanding why the baseline shifted.

Cameras got better faster than networks got easier

Phone cameras now routinely shoot RAW-adjacent formats and high-bitrate 4K video by default. A single minute of 4K video is commonly hundreds of megabytes, before any editing has even started.

More creative work happens on personal devices

Video editing, 3D and game-asset work, and high-resolution design files that used to live exclusively on a studio's internal network are now just as often produced on a laptop at home — and need to move around the same way any other file does.

Cloud backup habits shifted the baseline

Full-resolution photo and video libraries syncing across devices in the background has become ordinary, which normalizes moving multi-gigabyte batches as a routine task rather than a special occasion.

Why this matters for how tools get built

A size cap that felt generous when "large" meant 50MB starts to feel arbitrary and punishing once "large" routinely means multiple gigabytes — exactly the pressure behind the shrinking free-tier size caps covered elsewhere on this blog.

What actually scales with this shift

A transfer method with no server-side storage in the middle doesn't need to keep raising a cap as files get bigger, because there was never a size-dependent storage cost driving the cap to begin with.
