Zynk vs WeTransfer

WeTransfer is the name everyone knows for transfer links. But every file uploads to its servers, Free caps at 10 sends or 3 GB a month, links expire in 3 days, and nothing is end-to-end encrypted. With Zynk the file goes from your device to theirs, encrypted, with no server copy in the middle.

Your free plan shouldn't cap you at 10 sends or 3 GB across 30 days.
You want a menu-bar tray, a conversation, in-app preview, voice notes, and PDF signing in the same app.
You want share links, drop links, and a CLI alongside direct transfer.

What we noted

WeTransfer is the widely recognized name for browser-based transfer links.
When the recipient is a stranger who should just click a browser link, WeTransfer's reach and familiarity are real assets. Zynk's direct model is the stronger pick when you control both ends or send to the same people often.
