Key notes
A few Slack users have had a hard time uploading files to the shared channel or via direct messages. Allegedly, the upload was stuck and Slack was processing the file without any signs of success.
Slack, the team collaboration service, is one of the most used services in the niche. There’s a large array of available features, and it covers everything an organization needs.
Now, if you’re facing the same issue, firstly, make sure that the file isn’t corrupted. Secondly, there’s a size limit, so uploading files over a few dozens of megabytes won’t work all that well.
In case you encounter this problem, you should definitely check first if Slack servers are down. To easily do it, just access theSlack status official page.
On the other hand, if you’ve covered those two and the issue persists, check the alternative steps we enlisted below.
What files can I upload on Slack?
To improve your work efficiency with your team, you can add files to your Slack workspace. Files are searchable and shareable across Slack, so it’s handy for everyone to find the information they need and work together.
Keep in mind that you can share just about any file type up to 1GB in size in Slack from your device, or add them from a file management app like Box, Dropbox, Google Drive, or OneDrive.
Posts let you collaborate and share fully-formatted documents with your teammates directly in the app. Do not forget that even if you’re allowed to view posts on Slack’s mobile apps, you’ll need to use the desktop client to create and edit them.
Now, let’s see what you can do if Slack got stuck while processing the uploaded file.
What can I do if Slack is stuck while processing uploaded file?
1. Check your Internet connection
First things first. A mere glance at this issue is enough to concur something’s wrong with your connection. Uploading files should be an integral part of the application, both for desktop and in the browser.
We suggest trying to upload some files in the desktop app (if uploads get stuck in the web app) or the web app. If you’re still unable to upload files to Slack, some connection troubleshooting is more than welcome.
Here are some steps you should follow:
2. Use an alternative browser
Sometimes, the best way to get rid of Slack issues is by switching to a specialized browser and accessing the app from its main context menu. In this matter, we strongly recommend tryingOpera One.
When you switch Internet browsers to Opera One, you will automatically be prompted to import whatever data you want from your old web browser.
For those of you who are already using Opera One, keep in mind that you can import everything by following the steps below. Lose nothing, gain everything when you switch Internet browsers.
This option offers a Sidebar, located in the left window pane. There, you’re allowed to quickly access your Workspaces, Messengers, Speed Dials, Flow, bookmarks, personal news, tabs, history, extensions, downloads, and preferences.
Thus, you’ll always be able to add Slack to Opera One Sidebar and use it in no time.
If you choose Opera One, you can easily customize it to meet your needs, find thousands of extensions in the Opera One add-ons store, and use Chrome extensions as well.
The built-in ad blocker not only removes distractions and speeds uploading but also includes cryptocurrency mining protection. So, you won’t have to worry about data leakage when keeping in touch with your colleagues on Slack.

3. Clear browsing data (for browser version)
If you’re accustomed to the web app and the problem with uploads keeps reappearing on regular basis, tryusing Browser Refresh to refresh caches of several browsers. The cache and cookies tend to pile up fast.
In the long run, this can affect the performance of the browser: slow down the loading and prevent traffic on the individual pages.
It can, as well, inflict the issue at hand. You can discover above how to clear browsing data on the 3 most-used browsers for Windows 10 or 11.
If Slack is still stuck while processing the uploaded file, make sure you also verify the other listed solutions.
3. Disable antivirus temporarily
Some users in distress addressed the issue by disabling the antivirus temporarily. Namely, thebest Windows 10/11 antivirus softwaremay slow down or even block Slack’s execution.
This mostly concerns the desktop application, but the web-based app can be blocked by the protective solutions, too.
Even though this mostly doesn’t apply to Windows Defender, you can try disabling the web-based protection for the time being and look for improvements.
4. Allow Slack in Windows Firewall
For free team communication, which includes files sharing, Slack needs to works freely. The common limitation which affects Slack’s performance is Windows Firewall.
Namely, even though it should be allowed by default, we encourage you to check the related settings and confirm it.
If Slack still seems to be stuck while processing the uploaded file, we have one more option you can try, but you should use it only in the last instance.
5. Reinstall the app
Finally, if Slack got stuck while processing the uploaded file and you’re using the desktop client for Slack, reinstalling it should be a good idea. Even though it’s unlikely, the corruption of installation files can happen.
And if that’s indeed the case, the best way to fix it is to completely reinstall the app. In addition, Slack comes in various versions.
So, if you’re having a hard time with the desktop client, the UWP version from Microsoft Store might do you good.
That’s it. If you’re aware of some alternative solutions, we encourage you to share them with us in the comments section below.
