How to Send Large Files Online (No Signup)

Sending a large file by email usually fails. Big File Sharing keeps private file sharing free: upload without an account, copy a private link, and the guest file is removed automatically after 24 hours by default. Create an account if you want dashboard storage.

Your first file transfers needs no signup. After sending it, create a free account to keep sharing temporary files from your dashboard; paid plans are optional.

This guide explains the full flow, what recipients see, and how to share safely.

What you need

A browser (desktop or mobile)
The file or files you want to send
A way to send the link (email, chat, SMS)

You do not need an account, app, or credit card for your first file transfers. Later transfers require a free account, not a paid plan.

Step 1 — Open the homepage uploader

Go to bigfilesharing.com. The upload box is on the homepage. Drag files onto it or click to browse. Multiple files can be sent together as one share group.

Step 2 — Upload over HTTPS

The transfer uses TLS/SSL in transit. Large files use resumable chunked uploads, so a brief network drop does not always mean starting over. Keep the tab open until you see the success screen with your link.

Step 3 — Copy the private link

Each transfer gets a unique, unguessable URL. There is no public gallery and no search page of other people’s uploads. Only someone with the exact link can download while the file is still available.

Share that link only with intended recipients. Treat it like a password.

Step 4 — Recipient downloads

Recipients open the link and download — also without signing up. If the retention window has expired, the file is gone and cannot be recovered. Re-upload if they missed the deadline.

Step 5 — Automatic deletion

Guest homepage transfers are automatically deleted after 24 hours. This keeps the free transfer flow private and predictable; registered users can keep selected files within their plan storage allowance.

Files processed by online tools (converters, resizers, formatters) are deleted after 2 hours.

Tips for a successful transfer

Tell recipients the file expires — don’t assume they will download days later
Use a stable connection for very large video or archive files
Do not post the download link on a public forum or social feed
If you need a converter first, use a tool, then send the result via the homepage uploader
