How To Upload Files To Slack

Do you have important files that you want to share with other people on Slack? Do you have those files on your device right now? If that’s the case, you can upload them directly to your channels and conversations on the app. Follow our quick guide below, and we’ll show you how to do so on the Slack desktop, mobile, and web app.


Aside from sending messages on conversations and channels, you can also share files on Slack. As such, you can upload information and documents in one place, making it easier for your members to access them.

You can upload a file directly from your device to Slack or use a third-party file management app. In our guide below, we’ll go with the former option.

Here’s our guide on how to upload files to Slack.

How to send files to your Slack channels

If you want to share files from your device with other Slack members, you can upload them through a channel or conversation on your workspace. In this way, there’s no need for you to use another app to send important files.

You can upload a file whether you’re using Slack on your phone or computer. Check our step-by-step tutorials below, and we’ll show you everything you need to know about doing so.

On your computer:

  1. Launch the Slack desktop app or open their web browser client and sign in to your workspace.
  2. Go to the channel or conversation where you want to upload a file.
  3. At the bottom right part of the message field, click the paperclip icon. You can also press Ctrl + U on your keyboard as a shortcut.

  4. On the menu that appears on your screen, select “Upload from your computer” and choose the files you want to upload.

  5. Hit the Send button to share the files to the channel or conversation. You have the option to add a message before uploading the files.

Alternatively, you can drag and drop up to 10 files instead of clicking the paperclip icon on the message field. You can also schedule the sending of files if you think that it’s not the right time to share them.

If you have file management apps like Google Drive connected to your workspace, you can use them instead of uploading files from your device. In this way, there’s no need to download the files manually before sharing them in the conversation.

On your mobile device:

  1. Open the Slack app and sign in to your account.
  2. Go to the conversation where you want to share a file.
  3. Tap the plus icon at the bottom of the message field.

  4. Select “Upload file” on the menu and choose the ones that you want to share.

  5. Tap the Send button to send the files to the conversation immediately.

Note: You can’t upload files that exceed 1GB.

On the other hand, you can schedule your message by holding on to the Send icon and selecting a date and time.

Slack automatically checks your files before uploading them to the channel or conversation. If the app detects some viruses or malware, it won’t upload the file.

To wrap things up

Now that you know how to upload files to Slack, you can share important PDFs, images, and other information on your channels and conversations on the app. With the help of this option, you can store all your work-related data in one place, where every member can access and use them with ease.
