mPDF VS gotenberg-php

Generating PDF documents out of your app's HTML output is a very common requirement and there are several open source libraries to accomplish this. I came across this need for my project recently and I evaluated many popular ones such as TCPDF, mpdf, FPDF, etc. But the one that truly stood up to my evaluation in terms of efficiency (minimal footprint) and ease of implementation was DOMPDF.

Not sure if it has all the things you need but we use https://mpdf.github.io/

I'm currently using mPDF for large reports including tables, graphs, and complex formatting.

mPDF (very similar to TCPDF)

Writing a piece of code for a problem that has already being solved, tested and approved by other developers slows down the development of an application by a huge amount of time. For instance, trying to create a functionality that enables PDF files to be downloadable on a website is a waste of time when you have a package like mPDF that does that.

About mPDF https://mpdf.github.io/ "mPDF is a PHP library which generates PDF files from UTF-8 encoded HTML."

For PHP-based applications I've used mPDF[0], which generates PDFs from HTML without using a browser. I'm sure it can't handle all the CSS bells/whistles that a "modern" website uses, but it's worked well for me.

There is also a PHP client to ease the interactions with the API: https://github.com/gotenberg/gotenberg-php

Async requests seem to work really well with Gotenberg. Out of curiosity, did you use Gotenberg PHP?

TL;DR: Gotenberg PHP is a PHP client for interacting with Gotenberg, a developer-friendly API to interact with powerful tools like Chromium and LibreOffice to convert many documents (HTML, Markdown, Word, Excel, etc.) to PDF.
