Best Filemail Alternative for Encrypted Transfers

Filemail is a Norwegian service popular for very large transfers — up to 500 GB on paid plans — with desktop and mobile apps for accelerated uploads. Its encryption is transport-only on standard tiers, with end-to-end encryption gated behind Business subscriptions. For most users who want stronger encryption at lower cost, the best Filemail alternatives are HexaTransfer (10 GB free, E2EE default, no account), SwissTransfer (50 GB free, optional E2EE, Swiss jurisdiction), Tresorit Send (5 GB free, E2EE default, HIPAA-ready paid tier), and Proton Drive Send (bundled with Proton accounts). Pick based on file size, encryption baseline, and whether you need a dedicated upload client.

What Filemail Offers

Filemail lets free users send 5 GB per transfer with account signup. Paid plans scale from Pro ($10/month, 100 GB) to Business ($20/month, 500 GB) to custom enterprise arrangements. The company differentiates on raw size and on its UDP-based acceleration protocol, which delivers faster sustained throughput over long-distance connections than plain HTTPS.

Encryption on standard plans is TLS 1.3 in transit and AES-256 at rest, provider-managed. End-to-end encryption is available on Business and Enterprise tiers via a separate "Filemail Encrypted" feature using customer-held keys. That gates genuine privacy behind roughly $240/year per user, which is out of scope for individual users and small teams.

Where Alternatives Improve on Filemail

Four areas where Filemail alternatives commonly outperform:

1. E2EE at lower price points — HexaTransfer, Tresorit Send, and Proton offer client-side encryption free or bundled with existing subscriptions.
2. No account requirement — HexaTransfer and SwissTransfer skip signup entirely for typical free-tier use.
3. Shorter default retention — 7 days aligns better with GDPR Article 5(1)(e) data-minimization principles.
4. Simpler compliance story — less metadata collected means less to disclose under GDPR Article 30.

HexaTransfer: E2EE Default, 10 GB Free

HexaTransfer encrypts with AES-256-GCM in the browser via the WebCrypto API. The key rides in the URL fragment and never reaches the server. No account, no email, no desktop app to install. 10 GB per transfer, 7 days retention, EU hosting.

The obvious trade-off versus Filemail is size: 10 GB vs up to 500 GB. For typical knowledge-work transfers (contracts, design files, medical images, engineering drawings) 10 GB is more than enough. For video post-production and raw-footage delivery routinely in the 50-200 GB range, HexaTransfer isn't a direct replacement.

SwissTransfer: 50 GB Free, Swiss Jurisdiction

SwissTransfer, operated by Infomaniak in Geneva, offers 50 GB per transfer free with 30-day retention and optional E2EE via password. No account needed. Swiss Federal Data Protection Act applies rather than GDPR or Norwegian law, which some users prefer for its strong privacy tradition.

E2EE is opt-in rather than default, so you have to remember the password-protect checkbox. For the size-to-privacy ratio, SwissTransfer is the strongest mid-range alternative to Filemail's paid tiers at a cost of zero.

Tresorit Send: Compliance-Ready E2EE

Tresorit Send offers 5 GB free with client-side AES-256 encryption by default. Paid Business plans add HIPAA Business Associate Agreements, SAML SSO, audit logs, download-count limits, and a dedicated admin console. FIPS 140-2 validated cryptography and ISO 27001 certification position Tresorit for regulated industries where Filemail's paid tiers also compete.

For organizations already paying Filemail Business ~$240/user/year, switching to Tresorit Business ($168/user/year) typically improves the compliance posture at lower cost. The free tier is narrower — 5 GB vs Filemail free's 5 GB — but the E2EE baseline is stronger.

Proton Drive Send: Bundled with Proton

Proton Drive (formerly Proton Drive) includes a Send feature bundled with the paid Proton Unlimited subscription ($9.99/month). Client-side encryption via OpenPGP, Swiss hosting, and integration with Proton Mail, Calendar, and VPN. File size depends on your storage tier — up to 500 GB on Unlimited.

For users already paying for Proton Mail or Proton VPN, Drive Send adds zero marginal cost and replicates Filemail's large-file ceiling with genuine E2EE. If you're not in the Proton ecosystem, the standalone value is weaker — buying a full Proton subscription just for Send is inefficient.

Comparison Table

| Service | Free limit | E2EE | Account | Retention | |---|---|---|---|---| | Filemail Free | 5 GB | No | Yes | 7 days | | Filemail Business | 500 GB | Yes (paid) | Yes | Up to 90 days | | HexaTransfer | 10 GB | Yes (default) | No | 7 days | | SwissTransfer | 50 GB | Optional | No | 30 days | | Tresorit Send Free | 5 GB | Yes (default) | No | 7 days | | Proton Drive Send | Bundled | Yes (default) | Yes | Persistent |

Where Filemail Still Wins

Filemail's desktop and mobile apps with UDP acceleration genuinely outperform browser uploads for multi-hundred-gigabyte transfers over transatlantic or transpacific links. If you're moving 300 GB ProRes footage from Oslo to Los Angeles on a regular schedule, a browser-based HTTPS upload will often underperform a purpose-built acceleration client. Filemail's .dmg and .exe clients and IBM Aspera's on-demand service remain the right tools at that scale.

For smaller transfers or for teams whose "large" files top out at 10 GB, the browser-based alternatives achieve equivalent practical throughput without the install friction.

Matching Alternative to Use Case

If your Filemail use has been mostly under 10 GB with account-signup friction annoying you, HexaTransfer is the cleanest switch. If you need the 50 GB band with optional E2EE, SwissTransfer. If you need HIPAA BAAs or audit logs at lower cost than Filemail Business, Tresorit Send. If you're already a Proton subscriber, use Drive Send.
