WeTransfer vs. Nextcloud - The Best WeTransfer Alternative for Businesses (GDPR-Compliant and Open Source)
Many businesses face the question: How can large files be exchanged securely, efficiently, and in a GDPR-compliant manner? Services like WeTransfer are simple, but they quickly reach their limits in professional environments:
- Data protection risks, such as storage in non-EU data centers or access by foreign authorities
- Lack of integration into corporate IT, for example no central identity management without additional functions
- Dependency on external providers and potential changes to terms and conditions or pricing models
- Cost increases when volumes or requirements grow
Many IT decision-makers are therefore specifically looking for a WeTransfer alternative for businesses that is GDPR-compliant, self-hostable, and secure. Nextcloud offers exactly that: an open-source cloud solution with full data control, integration, and predictable costs - operated as a managed service by WZ-IT or self-hosted.
This article systematically compares WeTransfer and Nextcloud from the perspective of companies that consider data protection, flexibility, and operational control to be crucial.

2. Brief Overview: WeTransfer vs. Nextcloud
WeTransfer - Simple, but with Limitations
WeTransfer is a cloud-based SaaS service for quick file sending. Upload files, generate a link, send. The free version allows up to 2 GB per transfer, for example; larger files require a paid WeTransfer Pro or Enterprise subscription. Security info: WeTransfer Security FAQ
WeTransfer offers SAML SSO with Microsoft Azure for enterprise customers in the Enterprise plan: How to configure SAML SSO on your WeTransfer workspace with Microsoft Azure
Note on data protection: Storage and processing via WeTransfer-controlled infrastructure may involve third-country transfers and CLOUD Act risks. A 2025 terms and conditions change with a possible AI training clause was withdrawn after criticism: The Guardian
Nextcloud - The Flexible Open Source Alternative
Nextcloud is an open-source platform under AGPLv3 and combines file storage, synchronization, and collaboration. Project page: nextcloud.com Background: Wikipedia - Nextcloud
Operating models: Self-hosting on-premise or as Managed Nextcloud with WZ-IT in German data centers.
