EasyOdt2Pdf - ODT to PDF converter with 5 backends for Dolibarr

EasyOdt2Pdf for Dolibarr — Universal ODT to PDF conversion

EasyOdt2Pdf solves a long-standing pain point in Dolibarr: native ODT-to-PDF conversion requires LibreOffice installed on the server, which is impossible on shared hosting and forces your customers to rent a VPS. This module ships five pluggable backends covering every scenario and picks the best available automatically.

The 5 conversion backends

Only the Remote Gotenberg backend requires outbound network. EasySoft Tech S.L. publishes a free public endpoint at https://odt2pdf.microservices.easysoft.es with no registration or API key required. You can also self-host Gotenberg on localhost with the bundled docker-compose.yml.

📦 Common use cases

• Invoices, quotes and delivery notes generated as ODT that need to reach the customer as PDF.
• Shared hosting where LibreOffice or any binary cannot be installed.
• Multiple Dolibarr installations sharing a central conversion service.
• Progressive migration from Dolibarr's native conversion to a more stable microservice.
• Optional post-processors: PAdES digital signature, watermarks, page numbering, Bates stamping, encryption — all in pure PHP.

✨ Features

• 🔌 Five conversion backends: pure PHP (mPDF), local LibreOffice, unoconv, Dolibarr native, remote Gotenberg.
• 🎯 Automatic selection with configurable fallback chain.
• 📑 Per-document-type override (invoices to Gotenberg, quotes to PHP, etc.).
• 🛠️ Interactive installer with OS detection and step-by-step guidance.
• 🔍 Exhaustive environment check: all 9 PHP execution functions probed individually.
• 📝 Immutable audit trail per conversion.
• 🔐 Ready for watermark, PAdES signature, encryption.

📋 How it works

1. Install the module under custom/easyodt2pdf/ and activate it.
2. The Status tab automatically scans your server and shows which backends are available.
3. Configure the mode in the Configuration tab: auto, a forced backend, or a per-doc-type override.
4. Every time Dolibarr generates an ODT (invoice, quote, delivery note…), the module converts it to PDF automatically.
5. The Log tab keeps an immutable trail of every conversion.
