File transfer guide

Send ZIP files email refuses to carry

Email gives up around 25MB. Transfilio's free plan carries ZIP archives up to 2GB, paid plans up to 100GB, and recipients download the archive exactly as you packed it — no unzip-and-inspect on our side, ever.

How it works with Transfilio

  • Free: 2GB per archive — roughly 80x a typical email attachment cap
  • Your archive is never opened or scanned; encrypted in your browser before upload
  • Resumable uploads mean a flaky connection doesn't restart a 10GB archive
  • One link for the whole delivery, with expiry and a download counter

Common questions

Why won't email send my ZIP file?

Most providers cap attachments between 20MB and 25MB. Upload the archive to Transfilio instead and email the share link — free up to 2GB, and up to 100GB per file on paid plans.

Does Transfilio open my ZIP to check the contents?

No. Archives can be encrypted in your browser before upload, which makes their contents unreadable to us by design.

Free 5GB tier. End-to-end encrypted. Never trained on your files.
