What is PDF SDK for PHP?

PDF SDKs (Software Development Kits) provide developers with the tools and libraries needed to integrate PDF functionality into their applications or websites. These SDKs offer features like viewing, editing, creating, converting, and annotating PDFs, allowing developers to build custom PDF solutions tailored to their needs. PDF SDKs often include APIs for manipulating text, images, and form data, as well as for handling document security, such as encryption and password protection. By using PDF SDKs, developers can add robust PDF capabilities to their software without having to build these features from scratch, saving time and resources.

    pdfRest API Toolkit

    pdfRest API Toolkit

    Datalogics Inc.

    pdfRest is a REST API for high-volume PDF processing, built on the Adobe PDF Library. Call it from any language to convert, generate, extract, secure, and prepare PDFs in production pipelines, chaining calls by passing a resource ID between steps. Convert Office, HTML, images, email, and Markdown to PDF, and PDF to Word, Excel, PowerPoint, images, Markdown, PDF/A, PDF/X, and PostScript. Generate PDFs from scratch with text, images, shapes, and attachments, with accessibility tagging. Extract via OCR, text/image extraction, form data, metadata, AI summarization, translation. Secure with signing, encryption, restrictions, watermarking, two-step redaction, and TDM Reserve to opt out of AI training. Handle prepress: color conversion, transparency flattening, page boxes, rasterization. Manage forms: import/export, flatten, XFA-to-AcroForm. Deploy on pdfRest Cloud (US or EU) or self-host via Docker, Kubernetes, or AWS Marketplace (BYOL) — same API, same code, just change the base URL.

    FPDF

    FPDF

    FPDF

    FPDF is a solution written in PHP that allows you to generate PDF documents directly from PHP, so you can use the PDFlib library. The F of FPDF means free, so you can use it for any purpose and modify it to your liking to satisfy your needs. FPDF does not need any extension for PHP (except Zlib to enable compression and GD for GIF support) and works with PHP5 (≥ 5.1), PHP7 and PHP8. The tutorials will allow you to quickly access FPDF. FPDF generates documents in many other languages apart from the Western European ones, like Central, Cyrillic, Greek and Baltic, if they have TrueType or Type1 sources with the set of appropriate characters. UTF-8 is also available. The speed of generation of a document is less than that of PDFlib. Without the resentment, however, is very reasonable and is adequate for the majority of cases, unless its documents are specifically compiled or extended.
