File sharing without an account: what works and what it costs you

You can send files without creating an account using TransferNow (up to 5 GB), Smash (no stated size cap), SwissTransfer (up to 50 GB, with a one-time email check per device), Wormhole, browser peer-to-peer tools such as TransferFiles.net, and local apps like LocalSend or PairDrop. Receivers almost never need an account either. What varies is how anonymous "no account" really is: some services still want an email address, and every option without an account gives up something, usually the ability to manage a transfer after you send it. The details below were checked against each provider's own pages in October 2026.

Who asks for what

"No sign-up" is used loosely in marketing. This table separates a full account, an email check, and genuinely nothing.

The recipient column is nearly all "nothing" because services want downloads to be frictionless. The one common exception is a cloud link restricted to specific people: Google's Gmail help notes that only people with a Google account can see Drive files shared that way, while a link set to "Anyone with the link" works for everyone.

Why people avoid accounts

Wanting to skip a sign-up form is not only about saving thirty seconds. The common reasons are reasonable ones.

Less data about you in one more place

An account ties your name, email and every transfer you have made into a history stored by the provider. That history can be breached, subpoenaed, or used for marketing. A one-off transfer leaves a much smaller footprint.

No inbox follow-up

Accounts usually come with onboarding emails, upgrade offers and newsletters. People sending one file to a printer or a landlord do not want an ongoing relationship with a transfer company.

Shared or work computers

On a library PC, a client's laptop or a kiosk, signing into a personal cloud account means typing a password on a machine you do not control, and possibly forgetting to sign out. A no-account tool leaves nothing logged in behind you.

Separating identities

Freelancers, journalists and people in sensitive situations often prefer that a file transfer is not linked to their main Google or Microsoft identity. Note that "no account" is not the same as anonymity: the service and your network can still see your IP address, and anything inside the file (metadata, document author fields, photo location data) travels with it.

What you give up without an account

Accounts exist because they do useful things. Before going account-free, check you can live without these.

• Managing transfers after sending. With an account you can usually delete a transfer early, see whether it was downloaded, or extend the expiry. Anonymous transfers are typically fire and forget until they expire.
• Higher limits. Providers reserve their bigger quotas for registered or paying users. Filemail and Dropbox require an account even for their free tiers.
• Permanent links. No-account services delete files within days. If the file must stay available, a cloud storage account is the right tool.
• Access control. Restricting a link to specific named people needs those people to have identities, which means accounts somewhere.
• Accountability for recipients. A link from a known account with your name on it is easier for a recipient to trust than an anonymous one. Anonymous transfer links are also a favourite of phishing campaigns, so tell the recipient to expect your file.

The most account-free option: send directly

Upload services that skip accounts still hold your file on their servers for days. If the goal is to minimise what any third party has, a direct transfer goes further, because there is nothing to store and therefore nothing to tie to an identity.

On the same network, LocalSend is a free open-source app for Windows, macOS, Linux, Android and iOS; its site says it needs no account, no login and no servers, and data stays on your local network. PairDrop is a browser-based, open-source peer-to-peer option with no setup or sign-up.

Across the internet, TransferFiles.net works in the browser with no account, email or app on either side. The sender gets a link and a short code, the receiver opens it, and the file streams directly between the two browsers over WebRTC with mandatory encryption. Files are not uploaded or stored. Two servers are involved and it is worth being precise about them: a signalling server introduces the browsers to each other, and when a strict firewall prevents a direct route, the still-encrypted data is relayed through a TURN server that cannot read it. The trade-off is that both people must be online at the same time and keep the page open until the transfer finishes; there is no link to collect later. For that, one of the upload services above is a better fit. Our page on peer-to-peer file sharing explains the approach in more depth.

Wormhole sits between the two models: files up to 5 GB are encrypted in your browser and stored on its servers for 24 hours, with the key kept in the part of the link after the # so the server cannot read the files; above 5 GB it switches to a peer-to-peer transfer and you keep the page open.

When someone needs to send a file to you

Most no-account tools are built around the sender. If you need to collect a file from someone else without either of you signing up, there are two simple patterns. The first is to ask them to use a no-registration upload service and email or message you the link; you download it without an account. The second, if you can both be online at once, is to let them open a direct transfer page and read you the short code or send the link, so the file arrives in your browser while you wait. What usually does not work without an account is a permanent "drop files here" request page: those collection features, such as file request links in cloud storage, generally need the person receiving to have an account so the uploads have somewhere to land.

Choosing a no-account service you can trust

Without an account, the service's design is your only protection. Run through these before sending anything personal:

1. Find the operator. A real company name, country and privacy policy are minimums. SwissTransfer, for example, is run by Infomaniak in Switzerland and says so plainly.
2. Check retention. Know how many days your file will sit on the server, and whether you can choose a shorter period.
3. Check encryption. HTTPS in transit is standard. End-to-end encryption, or a direct transfer, means the provider cannot read the file at all.
4. Look at the link. Anyone holding a transfer link can usually download the file. Send it through a channel you trust, and use a password if the service offers one.
5. Clean the file. Strip location data from photos and author names from documents if anonymity matters.
6. Warn the recipient. A message saying what is coming and from whom helps them avoid fake download pages. Our guide on whether it is safe to receive files covers the receiving side.

Which to choose

For a quick file under 5 GB that someone will grab later, TransferNow or Smash are the simplest true no-registration options. For larger files or a longer download window, SwissTransfer is worth the one-time email check. If the provider should never hold a readable copy, choose Wormhole's end-to-end encryption, a direct peer-to-peer transfer, or a local app. And if you send regularly, need permanent links or want to know when something was downloaded, an account with a cloud service is honestly the better tool.
