WeTransfer is one of the most recognizable names in file sharing, and for good reason: it's simple, polished, and has been around for years. Realtime Sender takes a different approach, built around larger free transfers, privacy, and files that don't stick around. This guide compares the two fairly so you can pick the right tool.
Quick Verdict
If you want to send large files for free without an account and prefer files that auto-delete after download, Realtime Sender is the stronger fit. If you want a familiar brand, built-in email delivery, and don't mind the 2GB free cap, WeTransfer is a solid, well-known choice.
Side-by-Side Comparison
| Feature | Realtime Sender | WeTransfer (Free) |
|---|---|---|
| Free file size | Up to 30GB per file | 2GB per transfer |
| Account required | No | No (email for delivery) |
| Files auto-delete | After download or code expiry | After a set period |
| Sharing method | 6-character code or link | Email or link |
| Encryption in transit | TLS 1.3 | TLS |
| Registration to receive | No | No |
| Best for | Large, private, one-off transfers | Quick casual transfers |
Free File-Size Limits
This is the clearest difference. WeTransfer's free tier caps transfers at 2GB; anything bigger needs a paid plan. Realtime Sender lets you send up to 30GB per file for free, which comfortably covers 4K video, design projects, large archives, and datasets without splitting files or upgrading.
If your transfers are usually small documents and images, 2GB is often plenty. If you regularly bump into "file too big" limits, the higher free ceiling matters a lot. For more options, see our roundup of the best WeTransfer alternatives.
Privacy & Data Handling
Realtime Sender is built privacy-first: no account is required, and files are removed right after they're downloaded or once the share code expires. That means less data sitting on a server for less time. WeTransfer stores your file for a set window and typically associates the transfer with an email address for delivery and notifications.
Neither approach is "wrong" — they're different trade-offs. If minimizing stored data and staying anonymous matters to you, the auto-delete model is a meaningful advantage.

Expiry & Storage
Both services are temporary by design, but the timelines differ. Realtime Sender is a live, one-time transfer: the file is delivered and then gone, which is ideal for sensitive or one-off sends. WeTransfer keeps files available for a set number of days on the free tier so recipients can grab them later — handy when you're not sure when the other person will download.
Ease of Use
Both are genuinely easy. WeTransfer's flow is famously simple: add files, enter an email, send. Realtime Sender skips the email entirely — you get a short 6-character code (or a link) to share however you like: chat, SMS, or read it aloud. There's nothing to install on either service, and recipients don't need an account.
Where WeTransfer Wins
To be fair, WeTransfer has real strengths:
- Brand familiarity: recipients instantly recognize and trust it.
- Built-in email delivery: it emails the recipient for you, with notifications when they download.
- Later downloads: because files persist for a few days, timing matters less.
- Ecosystem & paid tiers: established paid plans with large storage and extra features.
Which Should You Choose?
Choose Realtime Sender if you need to send files larger than 2GB for free, you value privacy and auto-deletion, or you'd rather not tie a transfer to an email address.
Choose WeTransfer if your files are under 2GB, you want the recipient emailed automatically, or you specifically want a brand your recipient already knows.
