Team Messaging vs Dedicated File Sharing

Slack is a team messaging platform with file sharing as a secondary feature. The free plan provides 10 GB of total workspace storage, 1 GB per file upload limit, and automatically deletes files after 90 days. Slack does not offer end-to-end encryption—Slack employees can access all files and messages. The Pro plan costs $7.25 per user per month and provides unlimited storage retention.

FileShot is a dedicated file sharing service with zero-knowledge encryption built in. Free users get generous limits (10 GB per file free, unlimited storage on paid plans). Files are encrypted with AES-256-GCM in the browser before upload, and users can configure file expiry from 1 day to unlimited. FileShot never sees decryption keys, making true zero-knowledge file sharing possible.

Use Case Alignment

Slack is designed for team chat with incidental file sharing. If your primary need is internal team communication with occasional file attachments, Slack serves that purpose. However, Slack's free tier storage limits and automatic 90-day file deletion make it unsuitable for long-term file storage or large file transfers.

FileShot is purpose-built for secure file transfer to anyone—not just team members. If you need to send a confidential document to a client, share a large dataset with a collaborator, transfer files requiring zero-knowledge encryption, or store files with flexible expiry options, FileShot is the right tool. FileShot works for anyone with a link, not just workspace members.

Privacy and Encryption

Slack uses server-side encryption with keys managed by Slack. This means Slack can access your files and messages at any time. Slack complies with legal requests by handing over data, because they hold the keys. There is no zero-knowledge option on Slack—your data is visible to Slack administrators and anyone who compromises Slack's infrastructure.

FileShot's zero-knowledge encryption means files are encrypted before they leave your device. The decryption key lives only in the URL fragment and never reaches the server. Even FileShot cannot decrypt your files. This architecture eliminates trust requirements—you don't need to trust FileShot employees, infrastructure, or legal jurisdiction. The encryption guarantees privacy by design.

File Retention and Cost

Slack's free plan deletes files after 90 days automatically. If you rely on Slack for file storage, those files disappear unless you upgrade to a paid plan. The Pro plan ($7.25 per user per month) removes this limit but requires paying for every workspace member, even if they rarely share files.

FileShot gives you control over file expiry—choose 1 to 90 days per upload. Free users get 50 GB of storage (10 GB per file) and file size with no automatic deletion based on account type. Lite ($2/month) provides an ad-free experience with unlimited file expiry. Pro ($5/month) adds 100 GB per file and advanced features. You pay for your account, not per team member.

Who Should Choose FileShot?

If you need secure file sharing with zero-knowledge encryption, FileShot is the right choice. If you want to share large files with anyone (not just team members), FileShot handles that. If you need flexible file expiry without forced deletion, FileShot gives you that control. If you want generous free storage (50 GB total, 10 GB per file) without workspace limits, FileShot delivers it.

Slack is for team messaging. FileShot is for file sharing. If your use case is secure file transfer—especially with confidential documents or external recipients—FileShot is built for that purpose.
