MaraFile is a free, privacy-focused file sharing service that allows you to upload and share files securely without compromising your anonymity. Our mission is to provide a simple, secure, and accessible platform for anyone who needs to share files online while maintaining complete privacy.
Unlike traditional file sharing services that collect your data, track your activities, and potentially access your files, MaraFile is built from the ground up with privacy at its core. With optional end-to-end encryption, even we cannot access your files.
Whether you're sharing confidential documents, large media files, or simply need a temporary hosting solution, MaraFile provides the tools you need without requiring registration, personal information, or payment.
Choose one or multiple files to upload (up to 20 files at once, 1GB per file). You can either click the upload area or drag and drop files directly.
Turn on End-to-End Encryption (E2EE) for maximum security and privacy. When enabled:
Select how long your files should remain available - from 1 day to 3 months. Registered users can keep files indefinitely.
Click the upload button and wait for the process to complete. Our optimized chunked upload system ensures reliable transfer even for large files. Once complete, you'll receive a unique download link to share with anyone.
MaraFile is ideal for various use cases where privacy and security are important:
Your privacy is our top priority. Here's what we do to protect you:
Transparency is important. Here's exactly what we store:
Our E2EE implementation ensures maximum security:
Files are encrypted in your browser using the Web Crypto API before upload. The encryption happens on your device - never on our servers.
We use industry-standard AES-256-GCM encryption with random initialization vectors (IV) for each file, providing authenticated encryption.
The encryption key is generated in your browser and included in the URL fragment (#). This fragment is never sent to the server.
We never have access to your encryption keys or unencrypted data. Only people with the complete URL can decrypt files.

A: E2EE encrypts your files on your device before uploading using AES-256-GCM encryption. The server never sees your original files - only encrypted data. The decryption key is included in the URL fragment (#) and never sent to the server. This means even we cannot access your files without the complete URL.
How it works:
A: Yes! MaraFile is completely free to use with no hidden costs. You can upload files up to 1GB per file without registration. We're supported by optional donations and ethical advertising. Registered users get additional benefits like permanent file storage and higher upload limits.
A: No, you can use the service without registering an account. However, registered users can keep files indefinitely and access additional features.
Benefits of registration: Permanent file storage, file management dashboard, upload history, higher upload limits (coming soon), priority support, and API access (coming soon).
A: Most common file formats are supported including:
Security restriction: Executable files (.exe, .bat, .sh, .cmd, .msi) and some potentially dangerous formats are blocked for security reasons.
A: Copy and share the complete link that appears after upload.
⚠️ Important for encrypted files: Make sure to include the entire URL with the key fragment (#). Without the complete URL (including everything after the # symbol), encrypted files cannot be decrypted. The # fragment is never sent to the server, so it must be included in any link you share.
Secure sharing tips:
A: Only people with the download link can access the files. The links are randomly generated and cannot be guessed. With E2EE enabled, even we cannot decrypt your files without the key in the URL. Your files are as secure as you keep your download link.
Security levels:
A: You can choose retention periods from 1 day to 3 months. Registered users can keep files indefinitely. Files are automatically deleted after the selected period expires - no manual cleanup required.
Available retention periods:
A: Our chunked upload system automatically retries failed chunks. If the connection is lost temporarily, individual chunks are retried up to 3 times. If the upload is completely interrupted (browser closed, computer shutdown), you will need to start the upload again. For large files, we recommend a stable internet connection.
A: Yes, the current limits are:
These limits may be increased for registered users in the future.
A: Upload speed depends on your internet connection. Our optimized chunked upload system with dynamic chunk sizing (10-100MB) ensures maximum efficiency. You can monitor real-time upload speed and remaining time during the upload process. Most users experience near line-rate speeds.
A: Yes! There's no limit on how many times you or others can download files before they expire. Downloads don't count against any quota.
A: If you forget the URL, there's no way to recover it (we don't track which files belong to which users for privacy reasons). Make sure to save the URL immediately after upload. Consider:
A: If you need assistance, please contact us via the Contact page in the menu. We typically respond within 24-48 hours. For faster support, registered users get priority.
A: Yes! We accept ethical, non-intrusive advertisements. Please contact us via the Contact page for advertising opportunities.
