GitHub has become a cornerstone for developers and programmers around the globe, facilitating collaboration, version control, and code management. However, many users encounter challenges when trying to upload files to their repositories. If you’ve ever faced issues with GitHub upload files not working, you’re not alone. This article aims to provide a thorough examination of the possible reasons behind this issue, alongside proven methods and tips to resolve it effectively.
Understanding GitHub’s File Upload Mechanism
Before diving into troubleshooting, it’s vital to understand how file uploads work on GitHub. GitHub supports various methods of file uploads, including:
- The web interface for direct uploads.
- Git command-line interface (CLI) for version control and management.
When you try to upload files, GitHub processes your request through these channels, each having its unique protocols and potential points for failure. File uploads may fail due to network issues, browser compatibility, file size limitations, or even repository permissions. Understanding these nuances will better equip you to troubleshoot the upload issues you may experience.
Common Causes of GitHub File Upload Problems
To effectively address upload issues, it’s essential to identify the common factors that might be hindering your success. Here are some of the most frequent causes:
1. Network Issues
A stable internet connection is fundamental for uploading files to GitHub. Disconnected or unstable networks may interrupt uploads, causing them to fail.
2. File Size Limitations
GitHub has strict rules regarding file sizes. The maximum file size that can be uploaded through the web interface is 100 MB, while the Git command-line interface can handle larger files (up to 2 GB) if they are tracked correctly. If your file exceeds these limits, it will not upload.
3. Browser Compatibility
Not all browsers interact seamlessly with GitHub. Some users report that particular browsers lead to upload failures, while others work without a hitch. Always ensure you are using the latest version of a compatible browser such as Google Chrome or Firefox.
4. Repository Permissions
If you’re trying to upload files to a repository where you lack the necessary permissions, the attempt will fail. Only participants with write access can upload new files.
Troubleshooting GitHub Upload Issues
Once you identify the potential causes of your upload issues, follow these troubleshooting tips to resolve them.
Step 1: Check Your Internet Connection
Ensuring a stable internet connection is paramount. Here’s how to troubleshoot:
- Run a speed test to check your internet performance.
- Try reloading the page or disconnecting and reconnecting your internet connection.
If the connection seems stable, proceed to the next steps.
Step 2: Verify File Size and Format
Confirm that the files you are trying to upload do not exceed GitHub’s size limits. Here’s what you can do:
1. Check File Size
If any single file is larger than 100 MB for web uploads:
- Consider using Git LFS (Large File Storage) to manage large files.
- Alternatively, compress the file if acceptable.
2. Allowed File Formats
Make sure that the file format is supported by GitHub. While most formats are accepted, there may be restrictions on specific types.
Step 3: Clear Browser Cache
Over time, cache and cookies can build up and cause issues with web platforms like GitHub. Follow these steps:
- Open your browser settings.
- Look for privacy or history settings.
- Clear your cache and cookies, then restart your browser.

- Request write access if necessary.
Step 6: Use Command-Line Interface (CLI)
If the issue persists, try using Git through the command line. Here’s a quick guide:
- Open your terminal or command prompt.
- Navigate to your local repository.
- Use the following commands:
bash
git add [your_file]
git commit -m "Added new file"
git push origin [branch_name]
If this works, it indicates that the issue lies specifically with the web interface.
Advanced Solutions for Persistent Issues
If the conventional troubleshooting techniques do not resolve the upload issue, consider these advanced solutions.
1. Clone and Retry
Cloning your repository to a local machine and attempting the upload may help:
- Clone your repository:
bash
git clone [repository_url]
- Navigate into the repository folder:
bash
cd [repository_name]
- Add your files and push them back as noted in Step 6.
2. Enable Two-Factor Authentication (2FA)
If you are facing issues that hint at authentication problems, enabling 2FA might help. This additional security layer can sometimes resolve upload issues.
- Go to your GitHub settings.
- Enable Two-Factor Authentication and follow the prompts.
Make sure you have backup codes handy in case you need to authenticate anew.
3. Contact GitHub Support

What should I do if my file size exceeds the GitHub upload limit?
If your file size exceeds the GitHub upload limit of 100 MB, consider using Git Large File Storage (LFS). Git LFS allows you to store large files separately from your repository and manage them efficiently. You can install Git LFS on your machine and track the large files you need with simple command-line instructions.
If you choose not to use Git LFS, you may need to compress your file, split it into smaller parts, or use an alternative hosting service for large files, providing a link in your GitHub repo instead. Always keep the GitHub file size limitations in mind as you manage your repositories to avoid these issues in the future.
Why can’t I push files to my GitHub repository?
If you’re unable to push files to your GitHub repository, it may be due to issues with authentication. Ensure that your credentials are correctly configured, and you are using the right remote URL for your repository. You can check the remote URL by running git remote -v in your terminal. If you find discrepancies, use git remote set-url origin <new-url> to rectify it.
Another common reason for push failures is that your local repository may be out of sync with the remote repository. Before pushing your changes, it’s essential to pull the latest changes from the remote to ensure that there are no merge conflicts. You can do this by executing git pull origin main (or the name of your branch). After resolving any conflicts, you should now be able to push your files successfully.
What can I do if I get merge conflicts while uploading files?
When you encounter merge conflicts while uploading files, Git will notify you of the conflicts that need resolving. Begin by checking the status of your repository with git status, and Git will highlight the files with conflicts. Open those files to edit and manually resolve the differences between your local changes and the incoming changes.
After resolving all conflicts, stage the changes using git add <file> for each resolved file, and then commit the changes with git commit -m "Resolved merge conflicts". Finally, you can push your changes to the remote repository. It’s a good practice to frequently pull changes from the remote repository to minimize the chances of encountering merge conflicts in the future.
Why do my uploaded files not appear on GitHub after pushing?
If your uploaded files do not appear on GitHub after pushing, it may be due to pushing to a different branch than the one you’re viewing on GitHub. Make sure you are pushing to the correct branch by checking your local branch with git branch. If you need to switch branches, you can use git checkout <branch-name>.
Another reason could be that your push did not go through successfully due to network issues or authentication problems. Ensure you received a confirmation of the push in your terminal, and check your GitHub repository to confirm that the files were pushed correctly. If necessary, try running git push origin <branch-name> again to force the update.
What steps should I follow if I lose internet connection while uploading files?
If you lose your internet connection while uploading files to GitHub, the operation will be interrupted, and the files will not be uploaded. First, ensure your internet connection is restored and stable before trying to push your changes again. Check your connection by opening your web browser or executing a command in your terminal that requires internet access.
Once your connection is restored, you can use git push origin <branch-name> to attempt the upload again. It’s always a good idea to verify that all your changes are correctly staged before pushing. If necessary, you can check the status of your changes with git status to confirm everything is ready for upload.
How can I troubleshoot authentication issues with GitHub?
If you are facing authentication issues while trying to upload files, the first step is to ensure that your Git credentials are configured correctly. You can check your Git configuration with git config --list and look for the settings related to your username and email. If they are incorrect, use the git config --global user.name "Your Name" and git config --global user.email "[email protected]" commands to fix them.
Additionally, GitHub has shifted from basic authentication to requiring personal access tokens for many operations. If you have not set up a personal access token, log in to your GitHub account, navigate to settings, and create one with the necessary permissions. Use this token in place of your password when prompted during a push operation to resolve your authentication issues.
Why isn’t my local repository syncing with GitHub?
If your local repository isn’t syncing with GitHub, there could be several reasons behind this. First, check if you are connected to the internet and whether any network restrictions are present. You can test the connection to GitHub by running a simple ping test or trying to browse GitHub in your web browser.
It’s also possible that your local branch diverged from the remote branch. In such cases, fetch the latest changes from remote using git fetch origin, followed by git merge origin/<branch-name> to incorporate the changes. If there are conflicts, you will need to resolve them. Finally, after successfully merging the changes, you can push your local updates to GitHub.
How can I debug issues while using GitHub Desktop for uploads?
If you’re using GitHub Desktop and experiencing issues with uploads, the first approach is to ensure that the application is up-to-date. Check for updates within the application to ensure you have the latest features and bug fixes. An outdated version can lead to various issues, including failed uploads.
Additionally, reviewing the application logs can provide insight into the problems you are facing. Open the GitHub Desktop application, navigate to the “Help” menu, and select “Show Logs.” These logs can give you more details about the error events. If necessary, resetting your repository in GitHub Desktop might resolve lingering issues, allowing you to start your next upload attempt on a clean slate.
