Fix Gemini upload failed errors.
Upload failures are usually caused by unsupported file types, large files, stale browser sessions, account limits, temporary upload service issues or network interruptions.
Upload checklist
Reduce the upload until it works.
Browser
- Refresh Gemini and retry once.
- Try incognito with extensions disabled.
- Clear Gemini site data if incognito works.
- Try another browser or network.
Account/status
- Check whether your plan supports the file feature you are using.
- Try another Google account if policy allows it.
- If all uploads fail everywhere, check status sources and wait.
- Use a smaller excerpt if only part of the file matters.
