Check Existing Issues

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

Installation Method

Docker

Open WebUI Version

v0.6.13

Ollama Version (if applicable)

No response

Operating System

Ubuntu lts 24.04

Browser (if applicable)

Chrome 136.0.7103.125

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

While using the pdf exporter feature the resulting file is excessively heavy e.g. ~30 MB pdf. This shall be less than 100kB for only text of a small output.

I guess there is no proper compression and will try to pipe it to pdf2ps and ps2pdf to check on the size reduction.

I attached an example of the boilerplate prompt which results in 29MB pdf

Actual Behavior

Way too large pdf file for only text export.

Could not upload it to GitHub here is an example pdf.

Logs & Screenshots
