HTML-2-PDF API Service

Provides a single endpoint to convert raw HTML into a PDF document with an optional page size.

The container starts up a headless Chrome browser instance and creates pages with the HTML content provided to export to a PDF file. Even though JavaScript and service workers are disabled, you should host this in private and only use trusted HTML to avoid any security concerns.

Usage

The container exposes port 5000 so you can bind that to a port number of your choice (8080 in the example below).

docker run -p:8080:5000 deventerprisesoftware/html2pdf

Examples

cURL

curl \
-d '{ "html": "<h1>HTML 2 PDF</h1><p>Sample text</p>", "format": "A4" }' \
-H "Content-Type: application/json" \
--output test_file.pdf \
-XPOST "http://localhost:8080/"

C#

var request = JsonSerializer.Serialize(new { Html = "<h1>HTML 2 PDF</h1><p>Sample text</p>", Format = "A4" });

using var httpClient = new HttpClient();
using var requestContent = new StringContent(request, Encoding.UTF8, "application/json");

var response = await httpClient.PostAsync("http://localhost:8080/", requestContent);
response.EnsureSuccessStatusCode();

var pdfBytes = await response.Content.ReadAsByteArrayAsync();

await File.WriteAllBytesAsync("test_file.pdf", pdfBytes);
