[Stirling-PDF](https://www.stirlingpdf.com) is a robust, locally hosted web-based PDF manipulation tool using Docker. It enables you to carry out various operations on PDF files, including splitting, merging, converting, reorganizing, adding images, rotating, compressing, and more. This locally hosted web application has evolved to encompass a comprehensive set of features, addressing all your PDF requirements.
All files and PDFs exist either exclusively on the client side, reside in server memory only during task execution, or temporarily reside in a file solely for the execution of the task. Any file downloaded by the user will have been deleted from the server by that point.
- Optional Login and Authentication support (see [here](https://github.com/Stirling-Tools/Stirling-PDF/tree/main#login-authentication) for documentation)
- View and modify PDFs - View multi-page PDFs with custom viewing, sorting, and searching. Plus on-page edit features like annotate, draw, and adding text and images. (Using PDF.js with Joxit and Liberation fonts)
- Full interactive GUI for merging/splitting/rotating/moving PDFs and their pages
- Merge multiple PDFs into a single resultant file
- Split PDFs into multiple files at specified page numbers or extract all pages as individual files
- Reorganize PDF pages into different orders
- Rotate PDFs in 90-degree increments
- Remove pages
- Multi-page layout (format PDFs into a multi-paged page)
- Scale page contents size by set percentage
- Adjust contrast
- Crop PDF
- Auto split PDF (with physically scanned page dividers)
- Get all information on a PDF to view or export as JSON
- Show/detect embedded JavaScript
For an overview of the tasks and the technology each uses, please view [Endpoint-groups.md](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/Endpoint-groups.md).
A demo of the app is available [here](https://stirlingpdf.io).
For Windows users, download the latest Stirling-PDF.exe from our [release](https://github.com/Stirling-Tools/Stirling-PDF/releases) section or by clicking [here](https://github.com/Stirling-Tools/Stirling-PDF/releases/latest/download/Stirling-PDF.exe).
Stirling-PDF has three different versions: a full version, an ultra-lite version, and a 'fat' version. Depending on the types of features you use, you may want a smaller image to save on space. To see what the different versions offer, please look at our [version mapping](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/Version-groups.md). For people that don't mind space optimization, just use the latest tag.
Please note in the examples below, you may need to change the volume paths as needed, e.g., `./extraConfigs:/configs` to `/opt/stirlingpdf/extraConfigs:/configs`.
Certain functionality like `Sign` supports pre-saved files stored at `/customFiles/signatures/`. Image files placed within here will be accessible to be used via the web UI. Currently, this supports two folder types:
-`/customFiles/signatures/ALL_USERS`: Accessible to all users, useful for organizations where many users use the same files or for users not using authentication
-`/customFiles/signatures/{username}`: Such as `/customFiles/signatures/froodle`, accessible only to the `froodle` username, private for all others
Stirling PDF offers a Enterprise edition of its software, This is the same great software but with added features and comforts
### Whats included
- Prioritised Support tickets via support@stirlingpdf.com to reach directly to Stirling-PDF team for support and 1:1 meetings where applicable (Provided they come from same email domain registered with us)
There are two options for this, either using the generated settings file `settings.yml`, which is located in the `/configs` directory and follows standard YAML formatting, or using environment variables, which would override the settings file.
loginMethod: all # 'all' (Login Username/Password and OAuth2[must be enabled and configured]), 'normal'(only Login with Username/Password) or 'oauth2'(only Login with OAuth2)
termsAndConditions: https://www.stirlingpdf.com/terms-and-conditions # URL to the terms and conditions of your application (e.g. https://example.com/terms). Empty string to disable or filename to load from local file in static folder
privacyPolicy: https://www.stirlingpdf.com/privacy-policy # URL to the privacy policy of your application (e.g. https://example.com/privacy). Empty string to disable or filename to load from local file in static folder
accessibilityStatement: '' # URL to the accessibility statement of your application (e.g. https://example.com/accessibility). Empty string to disable or filename to load from local file in static folder
cookiePolicy: '' # URL to the cookie policy of your application (e.g. https://example.com/cookie). Empty string to disable or filename to load from local file in static folder
impressum: '' # URL to the impressum of your application (e.g. https://example.com/impressum). Empty string to disable or filename to load from local file in static folder
enableAlphaFunctionality: false # set to enable functionality which might need more testing before it fully goes live (this feature might make no changes)
showUpdateOnlyAdmin: false # only admins can see when a new update is available, depending on showUpdate it must be set to 'true'
customHTMLFiles: false # enable to have files placed in /customFiles/templates override the existing template HTML files
tessdataDir: /usr/share/tessdata # path to the directory containing the Tessdata files. This setting is relevant for Windows systems. For Windows users, this path should be adjusted to point to the appropriate directory where the Tessdata files are stored.
enableAnalytics: undefined # set to 'true' to enable analytics, set to 'false' to disable analytics; for enterprise users, this is set to true
There is an additional config file `/configs/custom_settings.yml` where users familiar with Java and Spring `application.properties` can input their own settings on top of Stirling-PDF's existing ones.
- **Endpoints**: Currently, the `ENDPOINTS_TO_REMOVE` and `GROUPS_TO_REMOVE` endpoints can include comma-separated lists of endpoints and groups to disable. For example, `ENDPOINTS_TO_REMOVE=img-to-pdf,remove-pages` would disable both image-to-pdf and remove pages, while `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/Stirling-Tools/Stirling-PDF/blob/main/Endpoint-groups.md).
- **customStaticFilePath**: Customize static files such as the app logo by placing files in the `/customFiles/static/` directory. An example of customizing the app logo is placing `/customFiles/static/favicon.svg` to override the current SVG. This can be used to change any `images/icons/css/fonts/js`, etc. in Stirling-PDF.
For those wanting to use Stirling-PDF's 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/Stirling-Tools/Stirling-PDF/), or navigate to `/swagger-ui/index.html` of your Stirling-PDF instance for your version's documentation (or by following the API button in the settings of Stirling-PDF).
- User must have the folder `./configs` volumed within Docker so that it is retained during updates.
- Docker users must download the security jar version by setting `DOCKER_ENABLE_SECURITY` to `true` in environment variables.
- Then either enable login via the `settings.yml` file or set `SECURITY_ENABLE_LOGIN` to `true`.
- Now the initial user will be generated with username `admin` and password `stirling`. On login, you will be forced to change the password to a new one. You can also use the environment variables `SECURITY_INITIALLOGIN_USERNAME` and `SECURITY_INITIALLOGIN_PASSWORD` to set your own credentials straight away (recommended to remove them after user creation).
When you log in to Stirling-PDF, you will be redirected to the `/login` page to log in with those default 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 the navbar). This Account Settings menu is also where you find your API key.
To add new users, go to the 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 and will be expanded on more in the future.
This is an issue commonly caused by your NGINX configuration. The default file upload size for NGINX is 1MB. You need to add the following in your Nginx sites-available file: `client_max_body_size SIZE;` (where "SIZE" is 50M for example for 50MB files).
NGINX has timeout values by default, so if you are running Stirling-PDF behind NGINX, you may need to set a timeout value, such as adding the config `proxy_read_timeout 3600;`.
