Features

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.

Speed

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.

Simplicity

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.

Security

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.

Custom branding · planned Pro

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.

Desktop app

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
