What is WeTransfer and what can you use it for?

WeTransfer is an online file-transfer service for sending large files to other people. You can send files without creating an account, and the recipient downloads them through a link. It is commonly used for photos, videos, and other files that are too big for ordinary email attachments. To send or receive files, you need a browser with JavaScript enabled.

What WeTransfer does

WeTransfer solves one specific problem: moving a large file from one person to another when email attachments are impractical.

The basic flow is:

1. You select the files you want to send.
2. You enter the recipient's email address (and your own).
3. WeTransfer uploads the files and generates a download link.
4. The recipient gets an email with that link and downloads the files.

The recipient does not need a WeTransfer account to download. The sender does not need one to send, either — the service is built around sending without an account.

Common uses

• Photos and videos — large image sets or video clips that exceed email attachment limits.
• Design and creative files — project files, mockups, or assets shared with clients or collaborators.
• One-off transfers — sending something to someone when you don't want to set up shared cloud storage or manage permissions.
• Cross-organization sharing — passing files to people outside your company or team.

If your goal is simply "get this big file to that person," WeTransfer is designed for exactly that.

What to know before you rely on it

JavaScript is required. WeTransfer's own site states that you need a JavaScript-enabled browser to use it. If JavaScript is blocked, the site may fail to load important parts, and you may see an error page instead of the upload interface.

Firewalls, proxies, and browser settings can interfere. WeTransfer notes that parts of its website may be blocked by your firewall, proxy, or browser setup. If the page won't load properly, the suggested fixes are refreshing the page or contacting the help center.

It is a transfer tool, not long-term storage. The purpose is sending files to someone, not archiving them. Treat the download link as a delivery mechanism rather than a permanent library.

Account-free sending is the core feature. The service is described as a simple, quick, and secure way to send files around the world without an account. If you specifically need account-based features, storage, or team management, check whether those exist separately — the no-account send is the baseline.

When WeTransfer is a good fit

Use it when:

• The file is too large for email.
• You want to send without signing up for anything.
• The recipient just needs to download, not collaborate in real time.
• You want a link-based handoff rather than shared folder access.

Look elsewhere when you need persistent cloud storage, ongoing collaboration on the same files, or fine-grained permission control — those are different problems than "send this large file now."

Quick verification checklist

Before sending, confirm:

• Your browser has JavaScript enabled.
• Your network (firewall/proxy) isn't blocking the site.
• You have the recipient's correct email address.
• The files are ready to upload.

If the site shows an error instead of the upload screen, the most likely causes are JavaScript being disabled or a network/firewall block — try refreshing first, then check your browser and network settings.
