Convert HTML to PDF in Android

HTML to PDF conversion is available for Android API 19 and above.

Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.

The HTML to PDF conversion API accepts different sources, such as HTTP/HTTPS URLs, HTML strings, and everything that can be loaded in a WebView.

From link

To convert a link URL to PDF, simply:

Java

public void convertFromUrl(Context context, String url, Uri folder, String outputFileName) {
    HTML2PDF.fromUrl(context, url, folder, outputFileName, new HTML2PDF.HTML2PDFListener() {
        @Override
        public void onConversionFinished(String pdfOutput, boolean isLocal) {
            // Handle callback when conversion finished
        }

        @Override
        public void onConversionFailed(String error) {
            // Handle callback if conversion failed
        }
    });
}

Kotlin

fun convertFromUrl(context: Context, url: String, folder: Uri, outputFileName: String) {
    HTML2PDF.fromUrl(context, url, folder, outputFileName, object : HTML2PDF.HTML2PDFListener {
        override fun onConversionFinished(pdfOutput: String, isLocal: Boolean) {
            // Handle callback when conversion finished
        }

        override fun onConversionFailed(error: String?) {
            // Handle callback if conversion failed
        }
    })
}

From HTML string

To convert an HTML string to PDF, simply:

Java

public void convertFromHtml(Context context, String baseUrl, String htmlSting) {
    HTML2PDF.fromHTMLDocument(context, baseUrl, htmlSting, new HTML2PDF.HTML2PDFListener() {
        @Override
        public void onConversionFinished(String pdfOutput, boolean isLocal) {
            // Handle callback when conversion finished
        }

        @Override
        public void onConversionFailed(String error) {
            // Handle callback if conversion failed
        }
    });
}

Kotlin

fun convertFromHtml(context: Context, baseUrl: String, htmlSting: String) {
    HTML2PDF.fromHTMLDocument(context, baseUrl, htmlSting, object : HTML2PDF.HTML2PDFListener {
        override fun onConversionFinished(pdfOutput: String, isLocal: Boolean) {
            // Handle callback when conversion finished
        }

        override fun onConversionFailed(error: String?) {
            // Handle callback if conversion failed
        }
    })
}

where myBaseUrl is the URL to use as the page's base URL. If null defaults to about:blank and myHtmlData is a String of data in the UTF-8 encoding.

From other sources

If none of the above fit your needs, you can also pass in a WebView directly for conversion:

Java

public void convertFromWebView(WebView myWebview) {
    HTML2PDF.fromWebView(myWebview, new HTML2PDF.HTML2PDFListener() {
        @Override
        public void onConversionFinished(String pdfOutput, boolean isLocal) {
            // do something with the PDF output
        }

        @Override
        public void onConversionFailed(String error) {
            // handle error
        }
    });
}

Kotlin

fun convertFromWebView(myWebview: WebView) {
    HTML2PDF.fromWebView(myWebview, object : HTML2PDF.HTML2PDFListener {
        override fun onConversionFinished(pdfOutput: String, isLocal: Boolean) {
            // do something with the PDF output
        }

        override fun onConversionFailed(error: String?) {
            // handle error
        }
    })
}
