Note: This ranking is for the specific scenario of sending files without creating an account. It is not an absolute security or capacity ranking. Always verify a service’s current terms before relying on it for sensitive data.
1. ShareIt.onl – Best for Flexible, No-Account Everyday Transfers
ShareIt Online is a browser-based service that is independent of the similarly named SHAREit mobile app. A basic share needs no app and no sign-up. You can upload up to 100 files totaling 3 GB in a single share. When the upload finishes, you get a web link and a QR code. The recipient downloads directly in their browser—no account, no app.
You choose the link expiry. Password protection and one-time links are available controls. If you want to keep files for re-use, the free account/storage offer includes 20 GB. Stored files can remain after an individual sharing link expires, so you can issue a fresh link without uploading the file again.
Request Files is a separate feature: the collector signs in free with Google, but contributors need no account or app. Each delivery can contain up to 100 files or 3 GB. Inbox links last 7 or 30 days, and received files are kept for 7 days, with each owner download extending that by 24 hours. The official page does not offer a password setting for inbox links.
Group Chat is invitation-only and requires members to sign in with a Google-connected account. It can attach active, reusable ShareIt links and works in desktop and mobile browsers. Message text, filenames, and new chat attachment copies are encrypted and decrypted in members’ browsers with AES-256-GCM. ShareIt stores ciphertext for synchronization but says it cannot read it. Original files in My Files stay separate and retain their normal ShareIt controls. Group Chat is plain text and currently has no calls, threads, bots, message editing, or push notifications.
When to choose it: You want a no-account send with controls like password protection and one-time links, plus the option to store files for later re-use. The Group Chat feature is useful if your team already uses Google accounts and needs encrypted text and file sharing.
Caveat: The browser-side encryption claim covers Group Chat text, filenames, and new chat attachment copies. Original My Files items remain separate and keep their normal controls. The service does not claim anonymity, and Group Chat requires a Google-connected account.
2. SwissTransfer – Best for Very Large Files Without an Account
SwissTransfer permits up to 50 GB per transfer without registration. Availability lasts up to 30 days, and you can optionally set a password and download limit. It encrypts in transit and at rest, but it is not end-to-end encrypted. The sender does not need to stay online after uploading.
When to choose it: You need to send a single very large file (up to 50 GB) to someone who can download it within 30 days. No account, no app, no staying online.
Caveat: SwissTransfer describes encryption in transit and at rest, not end-to-end encryption. Choose an end-to-end encrypted option when that distinction matters.
3. Wormhole – Best for End-to-End Encrypted Browser Transfers
Wormhole says files are end-to-end encrypted in the browser and can travel peer-to-peer or via an encrypted server copy. Check its current transfer instructions to see whether the sender must remain online for the mode you use.
When to choose it: You want a browser-based transfer with end-to-end encryption and peer-to-peer or encrypted server-copy delivery modes.
Caveat: The free size limit is not officially stated in the provided facts. Verify the current limit on the site before uploading a large file.
4. WeTransfer – Best for Quick, Familiar Transfers (With a Free Account)
WeTransfer’s current free account allowance is up to 10 transfers or 3 GB total in a rolling 30-day period. Free transfers remain available for 1 to 3 days. A free account is required for sending; verify the current recipient flow before an important delivery.
When to choose it: You already have a WeTransfer account or need a familiar interface for occasional small transfers. The recipient experience is simple and well-known.
Caveat: The free plan is limited to 3 GB total in a rolling 30-day period, and free transfers remain available for 1–3 days.
5. PairDrop – Best for Nearby Browser-to-Browser Transfers
PairDrop is a nearby browser-transfer option.
When to choose it: The devices are physically near each other and you want to try a browser-based handoff.
Caveat: Check PairDrop’s current connection and device requirements before relying on it for an important transfer.
6. LocalSend – Best for Offline Local Transfers (App Required)
LocalSend is a free, open-source app for transfers over a local Wi-Fi network. It does not require internet, an account, or a server. Both devices must have the app installed. The sender must stay online and within Wi-Fi range until the transfer finishes.
When to choose it: You frequently transfer files between devices on the same network and want a reliable, open-source solution that works offline. It is ideal for situations where internet access is unavailable or restricted.
Caveat: Requires installation on both devices. Only works on the same local network. No remote transfer capability.
Practical Advice for Choosing
For a one-off, no-account send with controls, start with ShareIt.onl. If you need end-to-end encryption for the file transfer, use Wormhole. For very large files (up to 50 GB), SwissTransfer is the capacity-focused option. For nearby devices, compare PairDrop’s browser workflow with LocalSend’s installed local-Wi-Fi app.
Always verify the downloaded file’s integrity—especially for large transfers—by checking the file size and, if possible, a checksum provided by the sender. No service guarantees that the file will arrive uncompressed or at original resolution unless you confirm after download. For sensitive data, use end-to-end encrypted options like Wormhole or ShareIt.onl’s Group Chat (with the Google account caveat).
