This is a powerful locally hosted web based PDF manipulation tool using docker that allows you to perform various operations on PDF files, such as splitting merging, converting, reorganizing, adding images, rotating, compressing, and more. This locally hosted web application started as a 100% ChatGPT-made application and has evolved to include a wide range of features to handle all your PDF needs.

Stirling PDF makes no outbound calls for any record keeping or tracking.

All files and PDFs are either purely client side, in server memory only during the execution of the task or within a temporay file only for execution of the task. Any file which has been downloaded by the user will have already been deleted from the server by that time.

Feel free to request any features or bug fixes either in github issues or our Discord

Environment variables are also supported and would override the settings file For example in the settings.yml you have

system:
  defaultLocale: 'en-US'

To have this via an environment variable you would have SYSTEM_DEFAULTLOCALE

The Current list of settings is

security:
  enableLogin: false # set to 'true' to enable login
  csrfDisabled: true

system:
  defaultLocale: 'en-US' # Set the default language (e.g. 'de-DE', 'fr-FR', etc)
  googlevisibility: false # 'true' to allow Google visibility (via robots.txt), 'false' to disallow
  customStaticFilePath: '/customFiles/static/' # Directory path for custom static files

#ui:
#  appName: exampleAppName # Application's visible name
#  homeDescription: I am a description # Short description or tagline shown on homepage.
#  appNameNavbar: navbarName # Name displayed on the navigation bar

endpoints:
  toRemove: [] # List endpoints to disable (e.g. ['img-to-pdf', 'remove-pages'])
  groupsToRemove: [] # List groups to disable (e.g. ['LibreOffice'])

metrics:
  enabled: true # 'true' to enable Info APIs endpoints (view http://localhost:8080/swagger-ui/index.html#/API to learn more), 'false' to disable

Extra notes
