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](https://discord.gg/Cn8pWhQRxZ)

## How to View
1. Open a web browser and navigate to `http://localhost:8080/`
2. Use the application by following the instructions on the website.
## Customize App
Stirling PDF allows easy customization of the visible application name.
Simply use environment variables APP_HOME_NAME, APP_HOME_DESCRIPTION and APP_NAVBAR_NAME with Docker or Java.
If running Java directly, you can also pass these as properties using -D arguments.
Using the same method you can also change
- The default language by providing APP_LOCALE with values like de-DE fr-FR or ar-AR (Note the - character not _ ) to select your default language (Will always default to English on invalid locale) Current accepted locales can be seen above in the Want to add your own language section
- Enable/Disable search engine visiblility with ALLOW_GOOGLE_VISIBILITY with true / false values. Default disable visiblility.
- Change root URI for Stirling-PDF ie change server.com/ to server.com/pdf-app by running APP_ROOT_PATH as pdf-app
- Disable and remove endpoints and functionality from Stirling-PDF. Currently the endpoints ENDPOINTS_TO_REMOVE and GROUPS_TO_REMOVE can include comma seperated lists of endpoints and groups to disable as example ENDPOINTS_TO_REMOVE=img-to-pdf,remove-pages would disable both image to pdf and remove pages, GROUPS_TO_REMOVE=LibreOffice Would disable all things that use LibreOffice. You can see a list of all endpoints and groups [here](https://github.com/Frooodle/Stirling-PDF/blob/main/groups.md)
- Change the max file size allowed through the server with the environment variable MAX_FILE_SIZE. default 2000MB
- Customise static files such as app logo by placing files in the /customFiles/static/ directory. Example to customise app logo is placing a /customFiles/static/favicon.svg to override current SVG. This can be used to change any images/icons/css/fonts/js etc in Stirling-PDF
- Enable/Disable metric api endpoints with ENABLE_API_METRICS. Default enabled
## API
For those wanting to use Stirling-PDFs backend API to link with their own custom scripting to edit PDFs you can view all existing API documentation
[here](https://app.swaggerhub.com/apis-docs/Frooodle/Stirling-PDF/) or navigate to /swagger-ui/index.html of your stirling-pdf instance for your versions documentation (Or by following the API button in your settings of Stirling-PDF)
## Login authentication (CURRENTLY ALPHA TAG ONLY)
### Prerequisites:
- User must have the folder ./configs volumed within docker so that it is retained during updates.
- The environment variable 'login.enabled' must be set to true
- The environment variables "INITIAL_USERNAME" and "INITIAL_PASSWORD" must also be populated (only required on first boot to create initial user, ignored after.)
Once the above has been done, on restart a new stirling-pdf-DB.mv.db will show if everything worked.
When you login to Stirling PDF you will be redirected to /login page to login with those credentials. After login everything should function as normal
To access your account settings go to Account settings in the settings cog menu (top right in navbar) this Account settings menu is also where you find your API key.
To add new users go to bottom of Account settings and hit 'Admin Settings', here you can add new users. The different roles mentioned within this are for rate limiting. This is a Work in progress which will be expanding on more in future
For API usage you must provide a header with 'X-API-Key' and the associated API key for that user.
