Why does Gemini always exceed the limit for uploading files? Google officially writes the limit very clearly: the same prompt can upload up to 10 files; Except for videos, the general maximum of supported files is 100MB; Videos can go up to 2GB, but there is also a limit to the total duration. The official help page also mentions that if you want a higher limit, you can upgrade to Google AI Pro or Google AI Ultra. The page is here: Upload and analyse files in Gemini Apps.
Which files are most prone to problems
Long PDFs, large tables, and mixed images are the easiest ways to make you feel like "it's clearly uploaded, but the analysis is incomplete." Google also warns that Gemini may miss details when files are too large, especially if the information is scattered across multiple pages.
The most practical way to deal with it
- First disassemble the large files into smaller ones, and then upload them in batches.
- Don't throw a bunch of irrelevant documents in at once.
- If it is used frequently and heavily, look at the upgrade plan.
In other words, it's not that Gemini can't use large files, but that you feed it according to its reading limit. The number of files, the volume, and the context window, any of which can make the results worse.
