Send Large Files – Free File Sharing and Transfer up to 10 GB. No Email Required.

FileBolt is a browser-based service for sending large files. Recipients download at full speed while you are still uploading, every file is end-to-end encrypted, and transfers pick up where they left off if interrupted.

How it works

  1. Choose files

    Pick files or drag them onto this page. Uploading starts right away.

  2. Share the link

    Send it any way you like, optionally with a password or an expiry date.

  3. They download

    Recipients open the link in any browser. No app, no account.

Why FileBolt

  • Global high-speed file transfer network visualization with low latency routing

    How fast is FileBolt? Fast across continents, even on shaky networks

    Global edge network:
    270+ edge locations and AI-driven routing pick the fastest path for every transfer.
    Built on HTTP/3:
    QUIC holds up on long-distance and lossy links: up to 5× faster than HTTP/2 on unstable networks, and about 1.25 GB/s peak on fast fiber in our tests.
    Proven since 2012:
    The transfer engine has been running in remote engineering sites since 2012.
  • End-to-end encryption shield and zero-knowledge privacy protection illustration

    Is it private? End-to-end encrypted, and you stay in control

    End-to-end encryption:
    Files are encrypted in your browser before upload, and the key never reaches our servers.
    Full control:
    Add a password, a download limit or an expiry date, see each download as it happens, and revoke a transfer at any time.
    Your terms:
    Show your own terms or disclaimer on the download page.
  • Sender and recipient exchanging files through one shared transfer link while the upload is still running

    Do I have to wait or sign up? No to both

    Download while uploading:
    Recipients can start downloading as soon as you share the link.
    No accounts, no ads:
    Nobody needs to sign up, neither you nor your recipients.
    Files back to you:
    Turn on “Recipient uploads” and clients can send files back through the same link.
  • Custom brand interface and multi-language localization showcase

    Can it carry my brand? Your logo, your client’s language

    Your branding:
    Put your logo and background on the transfer page.
    10 languages:
    Download pages and notification emails appear in your recipient’s language.
  • Comparison of file size limits showing 10GB free vs 5TB premium

    Half the usual price:
    Paid plans go up to 5 TB per file at about half the market rate.
