File delivery, without the side quest.
yasync moves large files from one person to another. Use the browser for quick sends and the desktop app for long ones. Pro adds developer tools and the CLI.
Fast from start to finish.
yasync uses your available connection and a worldwide download network.
Uses your connection
Files take a short route from your browser to secure storage.
Moves several parts at once
Large uploads are split into parts so problems can be retried without starting everything again.
Fast downloads worldwide
Recipients download through a worldwide network, close to where they are.
Drop. Link. Done.
No project spaces, no workspaces, no onboarding. The homepage is the product.
No account required
Send up to 5 GB anonymously now. A Free account raises that to 50 GB and adds history.
Folders welcome
Drop entire folders and keep their structure intact. Recipients can download everything together when the transfer is small enough.
One link, ready to share
Add an optional message, finish the upload, and copy the short link into whatever channel your team already uses.
Private links. Built-in checks.
Protect every transfer with a password and know when a file did not arrive correctly.
Passwords on every tier
Even anonymous sends can require a password. Recipients cannot see file names until they enter it.
Private download links
Each transfer gets a hard-to-guess link. Anonymous and Free links stop working after 24 hours.
Checks files during transfer
yasync checks each file before the link is ready. For supported downloads, the desktop app also checks the finished file.
Your brand on the link, not ours.
Custom download pages are included with Pro. Pro signup is coming soon.
Custom designs
Use your logo, colours, and background on download pages.
No automatic link expiry
Pro links stay live while the plan covers their storage, until you remove them.
No ads, ever
Pro pages are completely ad-free — for you and for everyone who opens your links.
For the transfers that take all night.
The desktop app remembers its progress through restarts and connection changes.
Resumes long transfers
After sleep, a connection change, or an app restart, compatible transfers continue from saved progress.
Send and download
Send project folders and download incoming links from the same app.
macOS, Windows, and Linux
The Apps page lists only verified macOS Apple Silicon, Windows x86_64, and Linux x86_64 packages and explains which installers include the CLI.
What yasync deliberately doesn’t do
- No media conversion or previews — your files are delivered untouched
- No review tooling, comments, or workspaces — this is delivery, not collaboration
- No download caps or fees — downloads are free on every tier, forever
- No scanning files for ads or profiling, and no AI training — on any tier
