Bug Report

Description

Bug Summary:
PDF files above 1 MB cannot be drag and dropped/uploaded via + into a chat and used. I quickly found wiki article that upon dowloading has 3 MB, but the file I encountered that with had little above 1 MB. Files below 1 MB are working fine.

Steps to Reproduce:
Take a PDF file above 1 MB and try uploading it to Chat instance

Observe that it is not being uploaded

Expected Behavior:
Files above 1 MB should get uploaded and be usable the same way as PDFs below 1 MB

Actual Behavior:
Upon file upload above 1 MB upload, nothing happens.

Environment

Open WebUI Version: [e.g., 0.3.8]
Operating System: [Ubuntu 20.04]
Browser (if applicable): [Firefox, Chrome, Brave, Edge, Opera - seems to be happening on all]

Reproduction Details

Confirmation:

I have read and followed all the instructions provided in the README.md.
I am on the latest version of both Open WebUI and Ollama.

Installation Method

Dockerfile

Additional Information

I'm using text-embedding-3-large as an embedding model for documents

Not sure if it affects other filetypes.

These are the files that you can try. First will work, second won't.
