Anonymity Is Not the Same as Privacy
Send.cm is an anonymous file sharing service with no registration required. You can upload files up to 10 GB, and they expire automatically after 7-30 days. The interface is simple, the process is fast, and there's no account to create. This is anonymity: no user tracking, no profile, no identity tied to your upload.
But anonymity is not the same as privacy. Send.cm uses server-side encryption, which means Send.cm can access your files. The service stores the decryption keys and controls access to the data. If someone compromises Send.cm's infrastructure, or if Send.cm receives a legal demand, your files can be accessed. You're anonymous, but your files are not private.
Zero-Knowledge Encryption: Privacy by Design
FileShot uses zero-knowledge encryption. Files are encrypted with AES-256-GCM in your browser before upload. The decryption key lives only in the URL fragment and never touches the server. FileShot cannot decrypt your files—even if we wanted to. This is privacy by design. Your files are encrypted, and only you (and whoever you share the link with) can decrypt them.
Registration is optional on FileShot. If you want to track your uploads, set custom expiry dates, or access premium features, you can create an account. But you don't have to. You can use FileShot anonymously with the same zero-knowledge encryption guarantees as registered users.
Storage and Upload Limits
Send.cm limits free uploads to 10 GB per file. Files expire after 7-30 days, and there's no way to extend that. There are no paid plans currently, which raises sustainability questions. A free service with no revenue model and significant infrastructure costs is difficult to maintain long-term.
FileShot offers 10 GB per file and 50 GB total storage on the free tier, with unlimited storage on paid plans. You choose the expiry date from 1 day to unlimited. The Lite plan is $2/month for an ad-free experience and unlimited expiry. Pro is $5/month for 100 GB per file and advanced features. Creator is $12/month with no limits. This is a sustainable freemium model—free users are supported by premium subscribers, and the business model is transparent.
Built-In Tools and Features
Send.cm is a single-purpose tool: upload a file, get a link, done. There's no file converter, no PDF editor, no compression tool, no metadata scrubber. If you need those features, you use a different service.
FileShot includes a full suite of privacy-focused tools: file converter, PDF editor, archive builder, file compressor, secure paste, file encryption, metadata scrubber, virus scanner, and video downloader. All tools are free, all respect your privacy, and all work client-side whenever possible. You don't need to bounce between services. FileShot is a privacy platform, not just a file host.
Desktop App and Cross-Platform Support
Send.cm is web-only. There's no desktop app, no browser extension, no mobile app. You use the website, and that's it.
FileShot has a desktop app for Windows, Mac, and Linux. There's a Chrome extension for quick uploads and screenshot capture. There's a PWA for mobile. The experience is consistent across platforms, and your encrypted files sync seamlessly.
Sustainability and Trust
Send.cm has no paid plans, no revenue model, and no clear path to sustainability. Free services with no monetization often shut down, change terms, or start selling user data. Without a business model, the long-term viability is uncertain.
FileShot runs on a transparent freemium model. Free users get full encryption, 50 GB of storage (10 GB per file), and access to all tools. Premium subscribers get extra features and support the service. This model is sustainable, predictable, and aligned with user privacy. You're not the product—your subscription is the product.
Who Should Choose FileShot?
If you need true privacy—not just anonymity—FileShot delivers zero-knowledge encryption as a default feature. If you want generous storage (50 GB free, unlimited on paid) with a clear, sustainable business model, FileShot provides that. If you need built-in tools, a desktop app, or the flexibility to choose your expiry dates, FileShot offers all of that.
Send.cm is fine for quick, anonymous file drops. But if privacy matters, if sustainability matters, if you want a full-featured platform that respects your data, FileShot is the right choice.
