How it works
Three steps. No manual.
If you can drag a file, you already know how to use yasync.
01
Choose files or a folder
Add an optional title, message, or password, then start sending.
02
Get a link
When the upload finishes, you get one short link to share.
03
They download — no signup
Recipients open the link in any browser. They do not need an account or app.
Desktop app + CLI
For long transfers.
The desktop app can resume work after sleep, connection changes, and restarts. Pro adds the CLI for automation.
The desktop app
Drop in a project folder, start the transfer, and get on with the rest of the day. yasync keeps its place when the machine or network does not.
- Keeps long transfers moving
- Resumes after sleep, connection changes, and restarts
- Checks supported downloads
- Keeps folder structure intact
The yasync CLI
Send files from scripts, render farms, servers, and scheduled jobs. The CLI requires Pro; the desktop app remains available to everyone.
$ yasync send ./final-renders --password

Fast transfers
Fast from start to finish.
Uploads take a short route to storage, and downloads use a worldwide network.
Fast downloads anywhere
Recipients download through a worldwide network, close to where they are.
Built for large uploads
Large files upload in several parts, so yasync can retry a problem without starting everything again.
Built-in file checks
yasync checks each file before the link is ready. For supported downloads, the desktop app also checks the finished file.
Unlimited downloads, included
Downloads are always free, whether one person uses the link or ten thousand do.
Privacy
Your files are none of our business.
We process files to store and deliver them, and disclose the providers that help us do it. The same privacy commitments apply to Pro, Free, and anonymous sends.
No profiling your files.
We process file content to store and deliver it, not to target ads or build a profile. A specific abuse report may be reviewed by an authorised person.
No AI training, period.
Your files never train machine-learning models — not ours, not anyone else’s. There is no fine print that changes this.
Your data is never sold.
We publish the provider used for storage and identify proposed processors for disabled features. We do not sell your data, and ads are never based on file contents.
Encrypted, and lockable
TLS in transit, encrypted at rest, and an optional password on every transfer — on every tier, including anonymous sends.
The full, plain-language version lives in our privacy policy.
Pricing
Free until it’s huge.
Anonymous and Free are available now. Pro with 1 TB included is coming soon. Downloads are always free.
The MASV math
They charge per download. We don’t charge at all.
MASV bills $0.25 per gigabyte every time someone downloads — a terabyte downloaded ten times runs about $2,500. yasync never charges for downloads.
See the honest comparisonMASV delivery
$0.25/GB
Billed on every download. Retries and extra recipients multiply the bill.
yasync delivery
€0/GB
Unlimited downloads at any scale. The planned Pro model charges for storage, not delivery; Pro signup is coming soon.
Good questions
The short answers.
The four things everyone asks first — the rest live on the FAQ page.
How big can I go?
Anonymous sends are live, and email-confirmed Free accounts unlock 50 GB transfers. Pro is coming soon.
How long do links last?
Free links expire after 24 hours. Files leave active storage and are purged from recovery storage within seven days. Pro links have no set expiry.
Can I set a password?
Yes — on every tier, including anonymous sends. Recipients see nothing until they enter it.
Do you look at my files?
We process files to store and deliver them. We do not scan them for ads, train AI on them, or sell your data — on any tier.
