10mb.net

One-line Introduction

10mb.net is a temporary file-sharing tool focused on end-to-end encryption. Developed and operated by a U.S. team, it lets users upload and share files for free while promising not to track user activity. Its biggest draws are “zero tracking” and “client-side encryption,” making it especially suitable for individuals or teams that need to send sensitive information quickly and securely without leaving a digital trail.

Business Overview

The core service offered by 10mb.net is a “burn after reading” style file-sharing experience. Users do not need to register an account: they simply upload a file to its servers, and the system generates a unique sharing link. The link can be configured with an expiration period, such as a few hours or a few days, or a maximum number of downloads. Once the link expires or the download limit is reached, the file is permanently deleted from the server.

Its “end-to-end encryption” means files are encrypted on the user’s device before upload, so even the service provider cannot view the file contents. This design is more privacy-focused than many mainstream cloud drives. Based on publicly available information, the service is aimed at individuals and small teams rather than enterprise customers. It does not appear to offer collaboration or administration features for businesses, nor does it publicly disclose its operating history or market share. Overall, it feels like a compact, privacy-first tool with some recognition among security-conscious geeks and certain professions such as journalists and lawyers.

Who It’s For

This tool is best suited to several types of users. First, privacy-conscious individuals who need to temporarily send things like ID photos, scanned contracts, or private images to friends, without wanting those files to remain in the cloud or be scanned and analyzed by the service provider.

Second, small teams or temporary project groups that need to quickly exchange files containing business secrets or sensitive data, such as project proposals or customer lists, but do not want to build or buy a complex enterprise-grade encrypted transfer system.

Third, journalists, lawyers, activists, and similar users who often handle highly sensitive information and have strict requirements for non-traceability and automatic file destruction.

Overall, it is not suitable for users who need long-term file storage, multi-person collaborative editing, or high-speed large-file transfers. It is also not ideal for business users who need invoices for reimbursement.

Key Features and Highlights

• End-to-end encryption (E2EE): Files are encrypted in the browser before upload, so the service provider cannot view their contents, ensuring privacy.
• Zero-tracking promise: The official statement says it does not record user IPs, file access logs, or any personally identifiable information.
• Free to use: Core features are currently completely free, with no mandatory paid tiers or hidden fees found.
• Automatic destruction mechanism: Supports setting file expiration periods and download limits; files are automatically deleted from the server afterward.
• No account registration: Uploading and sharing do not require an account, lowering both the barrier to entry and the risk of privacy exposure.
• Simple and easy to use: The interface is extremely minimal, and the workflow only requires three steps: select a file, generate a link, and share the link.

Pricing Analysis

Based on available information, 10mb.net’s core service is currently completely free, with no publicly listed monthly or annual plans. Among similar encrypted file-sharing tools, this is a rare “free lunch” positioning. Many competitors, such as Firefox Send alternatives and some encrypted cloud drives, either impose file size limits or require payment for end-to-end encryption or custom expiration settings.

10mb.net provides these features for free, giving it excellent value for money. However, users should note that there does not appear to be any publicly available information about paid add-ons, such as larger uploads or longer retention periods, nor any clear refund policy. Whether the service will introduce paid plans or impose limits on free users in the future remains unclear. For non-commercial, low-frequency temporary sharing needs, it is almost a zero-cost best choice.

How Chinese Users Can Use It

In terms of network accessibility, testing shows that the 10mb.net website can be accessed normally in most regions of China. However, upload and download speeds are affected by international bandwidth and may fluctuate, especially during peak hours. For small files of a few dozen MB, the experience is generally acceptable, but for larger files of several hundred MB, users may need to wait patiently.

As the service is free, there is no payment process involved. A proxy/VPN is not strictly required, but using one will usually provide more stable and faster transfer speeds, especially when downloading files.

As for domestic alternatives, there are file-sharing tools in China with similar “burn after reading” concepts, including some based on WeChat mini programs. However, most of them do not offer client-side encryption, so their privacy protection is not as strong as 10mb.net. For users who care deeply about privacy, 10mb.net remains the better option. That said, Chinese users should be aware that the service cannot issue Chinese invoices and does not provide Chinese-language customer support.

Pros and Cons

Pros:

• ✅ Very strong privacy protection: End-to-end encryption plus no tracking provides a high level of security.
• ✅ Completely free: Core features have no paywall, making it suitable for lightweight use.
• ✅ Extremely simple operation: No registration required, quick to get started, and suitable for urgent temporary use.
• ✅ Automatic destruction: Files are automatically deleted after expiration, reducing future risk.

Cons:

• ❌ Unstable speeds: Upload and download speeds from China are limited by international bandwidth.
• ❌ Single-purpose feature set: Only supports temporary sharing, with no storage, collaboration, version management, or similar features.
• ❌ No refund guarantee: The service is free, but there are also no paid options or clearly defined service-level agreements.
• ❌ File size limits: According to user feedback, individual files may be subject to an upper size limit, though the exact figure is not publicly disclosed.
• ❌ No enterprise features: Not suitable for business scenarios that require team management, audit logs, or invoice reimbursement.

Comparison with Similar Products

• Firefox Send (discontinued): Once a free encrypted file-sharing tool with a similar concept, but Mozilla has shut it down. 10mb.net can be seen as one of its spiritual successors.
• Tresorit Send: Also offers encrypted file sharing, but the free version has limits on file size and transfer volume. The paid version is more fully featured but relatively expensive. 10mb.net has the advantage in terms of being free, while Tresorit offers more mature enterprise-grade services.
• Wormhole: Another end-to-end encrypted file-sharing tool that supports peer-to-peer transfer and may offer faster speeds, but also lacks long-term storage. 10mb.net is more aggressive in its “no tracking” privacy promise.

Final Recommendation

Best for: 10mb.net is an excellent free option when you need to quickly and securely share a sensitive file that does not need long-term storage, such as a scanned contract, temporary password, or private photo, and you do not have strict requirements for file size or transfer speed. It is especially suitable for geeks, journalists, lawyers, and other individual users with high privacy requirements.

Not suitable for: If you need long-term file storage, team collaboration, very large file transfers such as video assets, or company reimbursement invoices and audit records, 10mb.net is not a good fit. In those cases, consider paid encrypted cloud drives such as Tresorit or Sync.com, or domestic enterprise cloud drive options such as Tencent Weiyun or Alibaba Cloud Drive enterprise editions.

Suggested action: Since it is completely free, there is no need to hesitate—just visit the official website and start using it. Upload a small file first to test whether the speed and features meet your expectations, then decide whether to use it as a regular tool. No payment is required, and there is no refund issue to worry about.
