What makes TeraSender different
Your files are not training data
TeraSender does not use uploaded files for AI model training. Files are encrypted in transit and at rest and deleted when the transfer expires.
Vouchers collect files for you
Send a voucher link and a client, contractor, or research partner can upload straight into your account — no sign-up on their side.
Uploads that survive bad connections
Every upload is split into chunks. If the connection drops, the transfer resumes from the last completed chunk instead of starting over.
Control over every link
Set an expiry date, add a password, and get an email the moment a recipient downloads. Revoke a transfer at any time.
Frequently asked questions
What is the best free WeTransfer alternative?
TeraSender is a free WeTransfer alternative that sends files up to 1 TB on Pro and 10 GB on the free plan, with end-to-end encryption, expiring links, and password protection included at no cost. Unlike some alternatives, TeraSender never uses uploaded files to train AI models.
Is TeraSender free like WeTransfer?
Yes. The TeraSender Free plan costs $0 and allows up to 10 files and 10 GB of total storage, with the same encryption and expiring download links as the paid plan. Pro costs $5 per month or $50 per year and raises the limits to 100 files and 1 TB.
Why are people looking for WeTransfer alternatives?
Interest in WeTransfer alternatives rose sharply after a 2025 change to WeTransfer's terms of service was widely read as granting rights to use uploaded files for AI training. WeTransfer later revised the wording, but many users moved to services with clearer commitments. TeraSender does not use customer files for AI model training.
Can I send files larger than 2 GB without paying?
Yes. TeraSender's free plan accepts up to 10 GB of total storage, so a single file well beyond the common 2 GB free ceiling can be sent without a subscription.
Does TeraSender delete files automatically?
Yes. You set an expiry date on every transfer, defaulting to 7 days. When a transfer expires TeraSender deletes the files from storage and the download link stops working.
