Original GitHub issue: https://github.com/open-webui/open-webui/issues/14729

Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Pip Install

Open WebUI Version

v0.6.13

Ollama Version (if applicable)

No response

Operating System

macOS Sequoia 15.5

Browser (if applicable)

Chrome 137.0.7151.68, Safari 18.5

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

Drag a PDF to a chat with any model, the backend should extract text from that PDF.

Actual Behavior

For certain PDF files, the default loader fails to extract text from PDF.

Steps to Reproduce

Drag this PDF to your WebUI interface:

My steps: - Start with the initial platform/version/OS and dependencies used, - Specify exact install/launch/configure commands, - List URLs visited, user input (incl. example values/emails/passwords if needed), - Describe all options and toggles enabled or changed, - Include any files or environmental changes, - Identify the expected and actual result at each stage, - Ensure any reasonably skilled user can follow and hit the same issue. ### Expected Behavior Drag a PDF to a chat with any model, the backend should extract text from that PDF. ### Actual Behavior For certain PDF files, the default loader fails to extract text from PDF. ### Steps to Reproduce Drag this PDF to your WebUI interface: [s41550-023-01945-7.pdf](https://github.com/user-attachments/files/20626664/s41550-023-01945-7.pdf) ### Logs & Screenshots The only relevant log is: ``` 2025-06-06 11:50:28.311 | INFO | open_webui.routers.files:upload_file:94 -

@astroboylrx commented on GitHub (Jun 6, 2025):

Okay, let me rephrase.
Would it be possible to allow users to point PDF to an external loader but still pass other types of documents to the default loader?
