Send files right from Slack.
Add the app to your workspace, link your SendThis account once, then run /send in any channel or DM.
Big files, straight from Slack.
Run /send and the app hands you a link and a button to add your files. Add them on SendThis, then post the link to the channel.
A link, not an upload
Post one short link to the channel instead of uploading the file into the workspace.
In your transfers
Everything you send through the app lands in My transfers, where you can change when it expires or delete it.
No ads, ever
Whoever opens the link gets the download page and nothing else. Not on the send side, not on theirs.
How it works.

- 01
Add the app
Install it to your workspace, then use it in any channel it is in, or message it directly.
- 02
Run /start and link
The app replies with a button that opens SendThis. Sign in, confirm, and the chat says you are connected.
- 03
Run /send
Get a link, add your files on SendThis, and post the link to the channel.
Questions.
How do I link Slack?
Run /start. The app replies with a button that opens SendThis; sign in, confirm, and the chat updates by itself. Nothing to copy.
What does the app do?
Run /send and it gives you a share link plus a button to add the files on SendThis. When they are up, the link is ready to post.
Where do my transfers go?
Into your SendThis account, beside everything you send from the web. Open My transfers to change when one expires, copy its link or delete it.
Do I need an account?
Yes. Linking ties the app to your SendThis account, so every transfer it makes is yours to manage.
Send your next file from Slack.
Add the app, link once, then /send from any channel or DM.
