Supported browsers
Send works directly in your browser — no app required. For the best experience, use:
DuckDuckGo
Firefox
Chrome (latest version)
Safari (on Mac or iOS)
Microsoft Edge
Older browser versions may still work, but you may encounter upload or download issues, particularly with larger files or multiple uploads.
Operating system compatibility
Send works on:
Windows (10 and above)
macOS
Linux (most major distros)
iOS and Android via mobile browsers (Chrome, Safari)
There’s no native mobile app (yet), but the mobile web version is fully functional, including uploading, sharing, and downloading.
File size and limits
Here’s what’s supported right now:
Up to 50 files per transfer
Maximum total transfer size: 4 GB
No folders (but zipped folders work just fine)
Transfers expire automatically after 7 days.
Internet connection
A stable connection helps, especially if you’re uploading larger files or hitting the 4 GB limit. If your connection drops, the transfer may restart from scratch.
Upload speed matters more than download speed here.
We don’t throttle bandwidth, but your ISP might.
JavaScript and cookies
Make sure both are enabled in your browser. We use them to:
Verify your email
Generate and track your transfer session
Let you copy the link after the upload completes
If you're using aggressive privacy settings or browser extensions (like ad blockers or anti-tracking tools), some features might not work correctly.
