Core Infrastructure

Never Lose Upload Progress.

Upload large files with any internet connection. Pause, resume, and continue where you left off. Perfect for slow WiFi, mobile data, or unstable connections.

Unstable Connections

Upload files even with frequently dropping connections. Perfect for rural areas, moving vehicles, or crowded public WiFi networks.

Mobile Data Ready

Switch seamlessly between WiFi and mobile data without restarting your upload. Great for heavy transfers while commuting or traveling.

Time & Bandwidth Saved

No more restarting failed 9GB uploads at 99%. Save hours of time and avoid burning your data caps on repeated failed attempts.

How Intelligent Recovery Works

  1. File Chunking

    Behind the scenes, FileXL slices your massive files into tiny verified chunks. As you upload, your browser logs exactly which chunks arrived safely.

  2. Connection Drops

    If your internet drops, your computer sleeps, or you change networks, the upload engine safely pauses. Just leave the tab open or return to the site later.

  3. Auto-Resume

    When you reconnect, the engine asks the server for the last verified chunk and continues exactly from where it left off. Zero data wasted.

Common Questions

No, that's the main benefit! Resumable uploads are specifically designed for unstable connections. Your upload automatically pauses when your connection drops and seamlessly resumes when it's restored. You can even switch networks (like moving from WiFi to cellular data) mid-upload.

FileXL stores your upload progress locally in your browser. This means you can start an upload, pause it, put your computer to sleep, and come back later to continue from exactly where you left off, provided you open the same browser session.

Currently, uploads are tied to the browser session on the specific device you started on. For security and technical reasons, you need to continue the upload from the same browser. However, you can close and reopen that browser safely without losing progress.

Upload confidently.
