How to send large files for free (up to 2 GB, encrypted) — 2026 guide
Email tops out around 25 MB. Chat apps compress your photos. And "share a folder" means the other person needs an account and the right permissions. Here's the fast way to send a big file — free, private, no signup.
The 20-second version
Go to cloudbox.biz, drop your file (up to 2 GB), and share the link. The file is encrypted in your browser before it uploads, so nobody — not even us — can open it without your link. The free link lasts 3 days.
Step by step
- 1. Choose your file — drag it onto the Send box, or click to browse. Up to 2 GB, any type.
- 2. Add emails (optional) — your email for a copy of the link, and the recipient's if you want CloudBox to email it to them for you.
- 3. Create the link — the file encrypts in your browser and uploads. You get a share link (or CloudBox emails it to your recipient).
- 4. Share it — copy the link anywhere, or let us email it. Done.
When to use a paid plan
The free tier covers 2 GB and 3-day links. If you need bigger files, links that last longer, or a permanent copy in your own storage, a plan from £0.99/month gives you a UK-hosted drive and longer link validity — and you can send straight from your account.
Why "encrypted in your browser" matters
Most transfer tools encrypt files in transit and at rest — but they hold the keys, so they can open your files. CloudBox is zero-knowledge: the key lives in your share link and never reaches our servers. That's real privacy for anything sensitive — contracts, medical scans, design files.
