PDF rendering library and command-line suite (pdftotext, pdfimages, pdftoppm, pdftocairo, pdftohtml, pdftops, pdfinfo, pdffonts, pdfdetach, pdfattach, pdfseparate, pdfunite, pdfsig) covering text/image extraction, page rendering, format conversion, metadata, attachments, and signature verification.
Command LinePDF viewer plus command-line tools (pdftotext, pdftops, pdftoppm, pdftopng, pdftohtml, pdfinfo, pdfimages, pdffonts, pdfdetach) for viewing PDFs and converting them to text, PostScript, image, or HTML, plus metadata, image, font, and attachment extraction.
Command LineCommand-line tool to merge, split, and rotate PDFs; fill forms with FDF/XFDF data and flatten them (or generate an FDF stencil); encrypt/decrypt with passwords; add watermarks/stamps; manage bookmarks, metadata, and attachments; repair damaged PDFs; and recompress page streams.
C#Reads and extracts text, words, letters (with position/font data), images, annotations, hyperlinks, embedded files, and bookmarks from PDFs (port of PDFBox); performs layout/reading-order analysis; supports basic PDF creation, merging, read-only AcroForm inspection, and opening password-protected documents.
C#Free GUI front-end for the PDFtk command-line tool on Windows: split, merge, stamp, add page numbers, rotate, edit metadata, bookmarks, and attachments — all via a graphical interface over PDFtk.
Generates PDFs from Clojure data structures: text/typography with custom TTF fonts, CSS-like stylesheets, lists, tables, multi-column layouts, SVG and image embedding, bar/line/pie charts, headers/footers, page numbering, document metadata, file attachments, and watermarks.
GoGo library for generating PDFs: text with UTF-8/RTL support, standard/TrueType/Type1 fonts, JPEG/PNG/GIF/TIFF images and basic SVG, vector graphics (lines, Bézier curves, arcs, gradients, transparency), barcodes, charts, outline bookmarks, internal/external links, page templates and importing existing PDFs as templates, layers, document protection/encryption, and file attachments/annotations.
Go PDF processor (CLI + library) supporting PDF up to 2.0 (ISO 32000-2): validate, optimize, split, trim, and merge PDFs; encrypt/decrypt; resize, rotate, and crop pages; extract/manipulate images, fonts, and metadata; manage attachments and portfolios; validate, report, and remove digital signatures; add/remove stamps and watermarks; process forms, bookmarks, and annotations; and generate booklets, N-up/N-down layouts, grids, and posters.
JavaContent-analysis toolkit that detects file types and extracts text and metadata from over a thousand file formats (including PDF, DOCX, PPTX, XLSX) through a single parsing interface; supports OCR (via Tesseract), language detection, named-entity recognition, and parsing of embedded documents/attachments. Available as a Java library, CLI (tika-app), or REST server (tika-server).
JavaRenders a practical subset of XML/XHTML/HTML5 with CSS 2.1+ (incl. CSS3 transforms, gradients, multiple backgrounds) to PDF or images, with SVG and MathML plugin support, accessible/tagged PDF output (Section 508, PDF/UA, WCAG 2.0), PDF/A compliance, font fallback and embedding, RTL/bidi text, footnotes, and file embedding via link download attributes.
Dependency-free JavaScript library (works in browsers, Node, Deno, React Native) to create PDFs from scratch or modify existing ones: add/insert/remove/copy pages, draw text (with embedded custom fonts), images (PNG/JPEG), vector graphics and SVG paths; create and fill AcroForm fields (text, checkbox, radio, dropdown) and read/flatten them; embed pages from other PDFs, split and merge documents, add file attachments, and read/set document metadata.
Laravel wrapper around Dompdf: converts HTML strings, files, or Blade views to PDF with paper size/orientation, DPI, fonts, CSS page breaks, and UTF-8 support; generates PDF/A-3b compliant output with embedded files and XMP metadata (for Zugferd/Factur-X e-invoicing); toggles JS/remote-content/PHP execution; outputs to disk, browser stream, download, or string.
PythonUnicode TrueType font subset embedding, cell/multi-cell/plaintext writing with automatic page breaks, optional Markdown-like text styling, image embedding with transparency, SVG import, arbitrary path drawing, table generation, internal/external links, barcodes/charts/emoji, document encryption and digital signing, annotations (highlights, file attachments), HTML-to-PDF conversion, basic math rendering, and TOC/outline generation.
RR bindings for extracting content from PDFs: `pdf_text()` for per-page text, `pdf_info()` for metadata (author, creation date, tags), `pdf_toc()` for table of contents/section headers, `pdf_fonts()` for font info, embedded-attachment access, and `pdf_render_page()` to rasterize pages to bitmap (e.g. PNG/WEBP). Does not handle table extraction (recommends the `tabulizer`/`tabulapdf` package) or OCR of scanned text (recommends the `tesseract` package).
RubyPDF library and CLI (positioned as a pdftk/Poppler-utils alternative): creates PDFs from scratch with vector drawing, JPEG/PNG/PDF image embedding, and TrueType text with subsetting; a high-level document composition engine (automatic layout, text flow, page breaks, lists, multi-column, reusable styles); modifies and merges existing PDFs; creates AcroForms with Adobe-like appearances; adds annotations, outlines, and file attachments; extracts metadata/text/images/files; encrypts (incl. PDF 2.0 AES-256) and digitally signs; and optimizes file size with object validation.
RubyPure-Ruby framework for parsing, modifying, and creating PDF files, with lazy on-demand parsing: compression filters with predictors, RC4/AES encryption (including Revision 6), digital signatures and usage rights, file attachments, AcroForm/XFA forms, and object streams. Ships CLI tools including `pdfcop` for detecting dangerous PDF content (not a full malware-analysis/forensics suite by the author's own description) plus decompression, decryption, encryption, resource-extraction, and metadata-inspection utilities.
