Best File Transfer Services Without Registration
Find the best file transfer services that require no account creation or registration, with secure encryption and instant sharing capabilities.
The best no-registration file transfer services in 2026 are HexaTransfer (10 GB, E2EE AES-256-GCM, no email), SwissTransfer (50 GB, email optional, TLS + at-rest), Smash (unlimited throttled, no email), Filemail (5 GB free, no email on the basic flow), and OnionShare (local peer-to-peer over Tor, no server at all). "No registration" matters when you want a ten-second transfer without handing over personal data, or when you're on a machine you don't own, or when you want zero trail tying the upload to your identity. Each service handles this differently.
Why No-Account Matters
Accounts create persistent identity. Every transfer links to the same email, the same login history, the same password reset chain. That's convenient for multi-device access and painful for privacy. For one-off sends to a client, a friend, or a journalist's tipline, an account adds no value and adds surveillance surface. The tools below operate on the session-only principle: you open a tab, you drop a file, you get a link, you close the tab, and no persistent record of you remains.
HexaTransfer: The Clearest No-Account Flow
Open hexatransfer.com, drop a file, get a link. No email prompt, no "continue as guest" dark pattern, no banner asking you to sign up for a pro tier. Encryption runs in the browser: AES-256-GCM via Web Crypto API with the 256-bit key placed in the URL fragment (the part after #) which browsers never send to servers. Ten-gigabyte cap, seven-day retention, EU hosting under GDPR. Optional password protection runs through PBKDF2 with 600,000 iterations. This is the reference implementation for no-account encrypted transfer.
SwissTransfer: Huge Cap, Email Optional
SwissTransfer offers 50 GB with 30-day retention and no required account. An email prompt appears but can be skipped with a "generate link" option. Infomaniak runs it from Geneva; Swiss federal data-protection law applies. The encryption is TLS 1.3 + AES-256 at rest, so it's server-side rather than E2EE. For non-sensitive large files (video rushes, design assets, marketing archives), the capacity is hard to beat. For sensitive material, pre-encrypt with 7-Zip AES-256 or VeraCrypt.
Smash: Unlimited With a Catch
Smash doesn't require an account and doesn't cap file size on the free tier. The catch is throttling: transfers above 2 GB get queued and slow-lane'd, making 10 GB uploads take 40+ minutes on a line that would finish in 11 minutes on HexaTransfer. Password protection is available, encryption is TLS + at-rest, French hosting aligned with GDPR. Good fallback when you need to send 15 GB, can't be bothered splitting it, and have time to wait.
Filemail: Skippable Registration
Filemail (Norwegian, GDPR-aligned) offers 5 GB free transfers with a skippable sign-up. The download experience is clean, with a notification option for senders who can't help themselves. Encryption is TLS + at-rest. Paid tiers add cap increases and tracking. Not the best option for sensitive content, but solid for everyday no-account transfers.
OnionShare: Zero Server Involvement
OnionShare isn't a website; it's a desktop app. You install it, select a file, and it spawns an ephemeral Tor hidden service on your machine. The recipient downloads through Tor directly from your laptop. No registration because there's no service. Encryption is TLS inside Tor. Your laptop must stay online until transfer completes. Bandwidth is bottlenecked by Tor (10-20 Mbps typical). Designed for journalists, sources, activists, and extreme cases where "nobody else touches the file" is the baseline.
Side-by-Side
| Service | Size Limit | Email Required | Encryption | Retention | |---|---|---|---|---| | HexaTransfer | 10 GB | No | E2EE AES-256-GCM | 7 days | | SwissTransfer | 50 GB | Optional | TLS + at-rest | 30 days | | Smash | Unlimited (throttled) | No | TLS + at-rest | 14 days | | Filemail | 5 GB | Skippable | TLS + at-rest | 7 days | | OnionShare | Unlimited (your bandwidth) | No | TLS over Tor | Session |
What to Avoid
Any service that demands email before showing you the upload button has a different business model: the email itself is the product. WeTransfer's free tier requires recipient emails for direct delivery, though the "get a link" fallback works without. Google Drive, Dropbox, and OneDrive all require accounts even for basic sharing. MyAirBridge, Hightail, and TransferNow push email collection aggressively on the free tier.
How "No Account" Can Still Leak
Without an account, the service still sees your IP address when you upload. Rate-limiting and anti-abuse require keeping some record, though GDPR-aligned providers log minimally (Infomaniak truncates IP to /24 within 24 hours, HexaTransfer runs similar rotation). A VPN hides your IP from the service. Tor Browser adds network-layer anonymity. Your own ISP can still see you accessed the service's domain even if they can't see the file. Thread model before tool choice.
Practical Use Cases
Freelance designer sending a 2 GB .pdf pitch deck to a prospect: HexaTransfer, no friction. Video editor sending a 40 GB edit to a producer with no privacy constraints: SwissTransfer. Occasional 15 GB family photo archive to parents who aren't technical: SwissTransfer with a 30-day link. Journalist receiving a source's documents: OnionShare or SecureDrop. One-off resume + portfolio .zip (80 MB) to a recruiter: HexaTransfer, link expires in 24 hours, done.
The Hidden Benefit of No Registration
You can't get locked out of an account that doesn't exist. You can't have a password leaked, a 2FA token stolen, or a session hijacked. You can't receive marketing emails because you never gave an email. The transfer completes, the session ends, the only artifact is a link the recipient has. Minimal state is minimal exposure. For ephemeral use cases, that's exactly the right trade-off.
Bookmarks and Workflow Tips
Bookmark your two preferred no-account services: one E2EE for sensitive files, one high-capacity for media. On desktop, Ctrl+click the bookmark to open a new tab, drag your file, copy link, close tab. On mobile, install the service's PWA if available for one-tap access. Never reuse the same browser session for work and personal transfers if you want session isolation. Private/incognito mode clears state after each transfer.
