Best file transfer services compared: WeTransfer vs the P2P alternatives (2026)

Every month, somebody asks the same question: which file transfer service should I actually use? The answer used to be easy — WeTransfer and done. Then WeTransfer cut its free plan to 10 transfers and 3 GB a month, tried to slip AI-training language into its terms, and got bought by Bending Spoons. Meanwhile a whole crop of peer-to-peer (P2P) services grew up that never touch a server at all. As of August 2026, this is a genuinely different landscape. Here's the straight comparison.

The short version: if you want a link that stays alive for days, the cloud senders (WeTransfer, TransferNow, Smash) work. If you want no limits, no upload, and nothing stored on a server, browser-based P2P wins. Pick per job — this post gives you the table.

The shortlist at a glance

• WeTransfer — the incumbent cloud sender. Simple, but the free tier is now heavily capped and it is not end-to-end encrypted.
• TransferNow — free 5 GB transfers, 7-day retention, no account needed. Solid free cloud option from France.
• Smash — markets unlimited size; big files are queued behind paid users on the free tier.
• SendAnywhere — the hybrid. 6-digit key pairs devices directly (up to 50 GB), plus classic share links.
• Snapdrop / PairDrop — the open-source P2P stalwarts. Files never touch a server, but everyone must be online at once.
• ToffeeShare — the zero-knowledge purist. Nothing is ever stored; the file only exists while the sender's tab is open.
• LocalSend — a native app (not browser) for LAN transfers that works fully offline.

Server-based services compared

Peer-to-peer and hybrid services compared

The server-based senders

WeTransfer: the incumbent, now on a leash

WeTransfer remains the most recognisable name, and its interface is still the smoothest way to email someone a few large files. But the free plan has shrunk hard: 3 GB per transfer, a rolling 30-day cap of 10 transfers or 3 GB total, and links that expire after 3 days. You now need an account. It is not end-to-end encrypted — files sit on WeTransfer's servers and are scanned or processed at their discretion. The July 2025 terms change that reserved rights over your files for AI training was reversed after a public backlash, but the episode told people what they needed to know. Paid tiers (roughly $10–$25/month) raise limits to 300 GB up to 1 TB per transfer, but they do not change the architecture: everything passes through their servers.

TransferNow: the generous free cloud tier

TransferNow quietly offers one of the best free cloud deals: 5 GB per transfer with no monthly quota, files available for 7 days, no account required, and password protection built in. It is GDPR-compliant (France) with AES-256 at rest and TLS in transit. The catch is the same one as every cloud sender — it is not end-to-end encrypted, and your bytes sit on their servers until expiry. For a one-off 'send this to a client' job it is hard to beat on the free tier.

Smash: unlimited size, with a queue

Smash is built around one promise: no size limit. True enough — free users can send files of any size, but anything over 2 GB gets queued behind paid transfers, which for a genuinely huge file can mean a long wait. Free links last 7 days and need only an email code. It is pleasant, has a nice carbon-footprint touch, and explicitly promises no AI training on your files. Like its peers it is not end-to-end encrypted. If you need a free no-limit cloud sender and can tolerate the queue, it is a reasonable pick.

The peer-to-peer crowd

Snapdrop & PairDrop: the open-source standard

Snapdrop was the original open-source, no-signup, WebRTC file drop, and PairDrop is the community-maintained fork that grew out of it — worth knowing because snapdrop.net itself was acquired by LimeWire and now routes your files through their cloud instead of peer to peer (the original code still works if self-hosted). PairDrop adds temporary public rooms (a 5-letter code or QR), persistent device pairing across networks, and TURN relay support so it works on strict NAT, VPNs, and public Wi-Fi. Files go straight between devices, encrypted with DTLS, and are never stored. Limits are set by your browser's memory rather than any server, so multi-GB transfers work in practice. The trade-off is fundamental to P2P: both people must be online at the same time, and there is no resume.

ShareDrop: the original, showing its age

ShareDrop pioneered room-based WebRTC sharing and deserves credit for it, but it has not aged well. Its chunked protocol with per-chunk acknowledgements caps throughput at roughly 30 MB/s even on fast links, it struggles on VPNs, and the project is effectively unmaintained — with community reports that sharedrop.io was also folded into LimeWire. For new projects, PairDrop is the more honest recommendation.

ToffeeShare: the zero-knowledge purist

ToffeeShare is the strongest 'nothing is stored' claim in this list. Files are encrypted end-to-end with DTLS 1.3 and never uploaded anywhere — the sender's browser holds the bytes and streams them directly to the receiver, using the shortest available path (it can even stay on your LAN). There is no size limit and no account. The flip side is strictness: the sender's tab must stay open for the entire transfer, there is no resume, and there is no history. A beta long-term sharing feature sidesteps this by storing files on a spare Android phone instead of a server. If zero-knowledge matters more than convenience, this is your tool.

LocalSend: offline LAN transfers, as an app

LocalSend is a native cross-platform app (Windows, macOS, Linux, Android, iOS) rather than a browser service, so it is a different category — but worth a mention because it is the best answer to 'I want to move files with no internet at all.' It discovers devices on your network, transfers over HTTPS with per-device certificates, and works fully offline. It is LAN-only, needs port 53317 open, and its self-signed certificates mean you should verify the PIN or fingerprint on public Wi-Fi. For same-network transfers it is superb.

The hybrid: SendAnywhere

SendAnywhere tries to have it both ways, and mostly succeeds. Its 6-digit key mode sets up a direct, end-to-end encrypted transfer between two devices — up to 50 GB free, no account, key valid for about 10 minutes. That is genuinely P2P. Its link mode, though, goes back to a server: 10 GB free per link, links live 48 hours, and free accounts get only 10 GB of download traffic per month across all their links. So the P2P side is excellent and the link side is tighter than TransferNow's. A solid choice if you want both modes in one app.

What actually matters when choosing

• Free limits — check the per-transfer cap AND the monthly cap. WeTransfer's free tier is the stingiest now; TransferNow and P2P tools have none.
• Retention — cloud links expire in days. P2P sessions only live while both people are online. There is no free way to get 30-day availability.
• End-to-end encryption — of the cloud senders, none are truly E2E. Every P2P tool here is, because there is no server to decrypt on.
• The online requirement — P2P needs both devices online simultaneously. If your recipient fetches links later, you need a cloud sender or cloud storage.
• Who owns the project — open-source P2P projects can change hands (see Snapdrop and ShareDrop). Prefer the actively maintained forks like PairDrop.
• No-install matters — browser-based services work on any device with no app, which is the difference between ShareFile, PairDrop, ToffeeShare and app-based LocalSend.

Where ShareFile fits

ShareFile is a browser-based peer-to-peer transfer built on WebRTC: you open a room, your peer joins, and the file streams directly between you. There is no signup, no account, no upload, and no file size cap, because nothing is ever stored on a server — matching the privacy model we've described here and the security properties of WebRTC's DTLS encryption. Unlike the cloud senders it stores nothing and cannot be capped. Unlike ToffeeShare or PairDrop it needs no code, no self-hosting, and no tinkering — just a link. And unlike an app like LocalSend it works across the internet in any browser. The honest trade-offs are the standard P2P ones: both people need to be online at once, and very strict corporate networks may block the WebRTC connection. If you want the full comparison of P2P versus cloud more generally, that is its own post.

The verdict, per use case

• Sending one big file to a client who is available now → P2P: ShareFile, PairDrop, or ToffeeShare. No limits, no upload, nothing stored.
• Leaving a link for people to grab over the next week → cloud: TransferNow (5 GB, 7 days) or Smash (bigger files, queued).
• Same-room, same-network, maybe no internet → LocalSend.
• Sensitive contracts or medical data → end-to-end P2P only: ShareFile, PairDrop, or ToffeeShare.
• Corporate sender with admin needs → a paid cloud tier (WeTransfer, TransferNow, Smash), or self-hosted PairDrop.
• You want the simplest possible one-off: no account, no app, no limits → ShareFile.

The cloud senders are competing on convenience; the P2P tools are competing on privacy, speed, and freedom from caps. As of 2026 the P2P side has caught up enough that for most one-to-one 'send it now' jobs it is simply the better deal. Try it once: open a room, share the link, and see your file travel direct — no account, no upload, no limits.
