WeTransfer Alternative: Secure and Private File Sharing in 2026

Sending a video project and sharing a confidential document are different jobs. Both need a reliable download link, but a contract, financial statement, or identity document may also need encryption that keeps its contents private from the service provider.

The right WeTransfer alternative depends on your file sizes, whether you need ongoing storage, and who should be able to access the contents. This guide compares PrivateNote, SwissTransfer, Proton Drive, Wormhole, and Smash by those requirements.

What to look for in a secure file-sharing service

Encryption before upload

HTTPS protects files in transit. Server-side encryption protects stored files, but the provider may still hold the keys needed to read them. End-to-end encryption changes that relationship: the sender’s device encrypts the content and the recipient’s device decrypts it, without giving the provider the decryption keys.

This is useful when the file should remain confidential from the transfer provider itself. It does not protect against every threat. Compromised devices, malicious browser extensions, and exposed sharing links can still undermine privacy.

Access controls

Encryption protects contents; access controls determine who can retrieve them and under what conditions. Look for password protection, recipient verification, expiration, opening limits, and revocation that match your workflow.

Send a transfer password through a different channel from the link. Email verification demonstrates control of an inbox, rather than proving a person’s legal identity. Neither protection prevents an authorized recipient from keeping a copy.

Practical limits

Check the maximum size of an individual file and the total allowed in one transfer. Monthly transfer allowances, storage quotas, and download windows also matter. A service that suits confidential PDFs may not suit a 40 GB video project.

1. PrivateNote: confidential documents and controlled access

PrivateNote encrypts file attachments in the sender’s browser before upload and decrypts them in the recipient’s browser. It combines that encrypted handoff with password protection and expiration, plus opening limits and recipient controls that vary by plan.

Senders need an account to attach files. Recipients do not need to register. Starter and Business add recipient email verification, a sent-notes overview, and revocation of unopened notes.

• Free: up to 25 MB per file and per transfer, with 10 file transfers per month.
• Starter: up to 250 MB per file and per transfer, with 50 file transfers per month.
• Business: up to 1 GB per file and per transfer, with unlimited file transfers.

These limits suit documents, photographs, and moderately sized archives. PrivateNote is not a replacement for a large-media delivery service when your project exceeds 1 GB. Check the current plans for the full limits and controls.

Choose PrivateNote when you want browser-side encryption and configurable access for sensitive files. Send an encrypted file, or read the detailed WeTransfer vs PrivateNote comparison.

2. SwissTransfer: large transfers without registration

SwissTransfer, operated by Infomaniak, supports transfers up to 50 GB without creating an account. It offers availability and protection settings, making it useful for large archives, photographs, and video projects. SwissTransfer’s official site

Its appeal is a generous transfer allowance without adopting a cloud-storage subscription. If your requirement includes keeping files unreadable to the provider, examine the encryption and key-management model separately. Large transfer limits and password protection do not, by themselves, establish end-to-end encryption.

Choose SwissTransfer when transfer size and an account-free sending workflow are your priorities.

3. Proton Drive: encrypted storage with sharing

Proton Drive combines end-to-end encrypted storage with file sharing. It is designed for retaining and organizing files over time, as well as sharing them with others. Its sharing controls include password-protected links and the ability to disable existing links. Proton Drive

This is a different workflow from uploading something solely for a temporary handoff. You can keep the document in your encrypted storage and manage access as your needs change. Storage capacity and feature availability depend on the plan.

Choose Proton Drive when you need encrypted storage across devices alongside file sharing.

4. Wormhole: straightforward encrypted transfers

Wormhole encrypts files in the browser before sending them. Its documented design supports peer-to-peer delivery and encrypted server storage, with decryption information carried in the sharing link’s URL fragment. Wormhole security design

It is an option for people who want encrypted file delivery without a broader storage system. Before a large transfer, check the current limits and whether the sender needs to stay online for that transfer mode.

Choose Wormhole when you want a simple encrypted handoff without organizing files in a cloud drive.

5. Smash: large creative files

Smash focuses on large-file delivery, making it relevant to photographers, designers, and video producers. Its help center states that the free version has no fixed file-size limit, but transfers above 2 GB are not prioritized and may enter a waiting queue. Smash file-size limits

That distinction matters when delivery is urgent. Evaluate the security architecture separately from transfer capacity if client-side encryption is a requirement.

Choose Smash when you regularly deliver large media assets and its transfer conditions fit your deadlines.

Which alternative fits your situation?

• Confidential documents: consider PrivateNote for encrypted delivery with configurable access controls.
• Large transfers without registration: consider SwissTransfer.
• Long-term encrypted storage: consider Proton Drive.
• Straightforward encrypted handoffs: consider Wormhole.
• Large creative projects: consider Smash, paying attention to queue and plan conditions.

There is no single winner across these jobs. A generous size allowance does not tell you who holds the encryption keys. End-to-end encryption does not tell you whether a service offers recipient verification or enough storage for your project.

What expiration and limited openings actually protect

A temporary link reduces the time during which someone can retrieve the hosted content. Opening limits also restrict repeated access through the sharing link. These controls help reduce exposure from forgotten links in old messages.

They cannot recall information already revealed. A recipient may download a file, capture the screen, or otherwise retain its contents. View-only interfaces cannot guarantee that copying is impossible.

Use expiration and opening limits to control future access to the hosted copy. Choose recipients with the understanding that they may retain what you share.

How to send an encrypted file with PrivateNote

1. Sign in and choose your files

Open Secure File Transfer, sign in, and select your attachments. Check both the individual file limit and the total transfer limit for your plan.

2. Configure access before sharing

Choose the available expiration and opening settings. Add password protection where appropriate. Paid plans provide additional recipient controls, including email verification.

3. Create and share the link

PrivateNote encrypts the file locally before uploading it. The sharing link carries decryption information in its URL fragment, after the # character. Browsers do not include that fragment in ordinary HTTP requests.

Treat the complete link as sensitive. Share it with your intended recipient, and send any password separately. The recipient completes the required checks and decrypts the content in their browser without registering.

4. Let access end

The configured expiration and opening limits restrict further access. A file-access window can allow the recipient to finish retrieving attachments after opening the note. On supported paid plans, you can also revoke an unopened note. These controls do not remove copies already saved.

Frequently asked questions

What is the best free WeTransfer alternative?

For large files, SwissTransfer is a strong candidate. For smaller confidential files, PrivateNote’s free account offers encrypted transfers with a 25 MB transfer limit. Proton Drive is worth considering when encrypted storage is also part of the requirement.

Which alternatives offer end-to-end encryption?

PrivateNote, Proton Drive, and Wormhole offer end-to-end encrypted sharing. Their storage models, transfer limits, and access controls differ, so choose based on the complete workflow.

Can I send files without creating an account?

Some services support account-free sending, including SwissTransfer. PrivateNote file senders need an account, while recipients can open shared files without registering. Text notes and file attachments have different sender requirements.

Does password protection mean end-to-end encryption?

No. Password protection is an access control. End-to-end encryption describes where encryption happens and who holds the keys. A service may offer either protection or both.

Can I stop a recipient from copying a file?

Not reliably once they can view its contents. Download restrictions can reduce convenient copying, but screenshots and other capture methods remain possible.

Share only for as long as necessary

Before creating a link, decide who should receive the file, whether the provider should be able to read it, and how long access needs to remain available. For confidential information, combine encryption with appropriate recipient checks and a short access window.
