Command LineLightweight C library, viewer, and CLI toolset for PDF, XPS, and e-book formats: renders and extracts text/images/metadata/structured content; creates, splits, merges, and compresses PDFs; adds annotations (highlights, stamps, shapes); permanently redacts content; digitally signs documents; converts between PDF, SVG, PNG, HTML, and PostScript; and embeds into web pages/apps.
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.
GoGo PDF library (pure Go): generates reports/invoices with styled text and tables; creates and fills forms; merges, splits, reorders, and rotates pages (incl. N-up layouts); extracts text (with position/formatting), images, and tabular data to CSV; adds/converts images to PDF; removes or adds password protection; validates and applies digital signatures; compresses/optimizes files; adds watermarks; and supports CCITTFax/JBIG2 image decoding.
GoGo 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.
GoSelf-hostable 'knowledge converter' that extracts highlighted text, formulas, and images from PDFs (plus Word/Excel/images, WeChat Reading notes, and mind maps) to generate Anki flashcards, using an LLM (Gemini, GPT-4, Claude, etc.) to identify key concepts automatically; also batch-exports Anki decks back to PDF.
JavaAndroid PDF toolkit centered on creating PDFs from camera/gallery images (and converting text files to PDF), plus managing existing PDFs: merge, split, compress, remove/rearrange/rotate pages, extract images, and encrypt/decrypt.
JavaAndroid port of Apache PDFBox for reading and manipulating PDF documents on-device, with image handling (including optional JPX/JPEG2000 support via JP2Android).
Node.js wrapper around PDFtk, Ghostscript, and ImageMagick for PDF manipulation: split/select/reorder/reverse pages, filter even/odd pages, join multiple PDFs, rotate (90/180/270/360°), crop (noted as unreliable), extract text and embedded images, extract metadata/properties, and render pages to PNG at a given DPI.
PythonPythonic wrapper around qpdf for reading, writing, and manipulating PDFs: merge, split, rotate, rearrange, and delete pages; read/write XMP and DocumentInfo metadata (auto-synced); losslessly extract or replace embedded images (preserving original JPEG compression); open password-protected files and save with RC4, AES-128, or AES-256 encryption (or remove it); linearize for 'fast web view'; direct object-level/content-stream access; automatic repair on open; access to qpdf's Job API; and Jupyter notebook preview rendering.
PythonConverts scanned-book PDFs to Markdown or EPUB using OCR (DeepSeek OCR locally, or DeepSeek/Baidu vendor backends), recognizing complex structure including tables and formulas; extracts body text while filtering headers/footers, preserves footnotes/images/assets, auto-generates an EPUB table of contents (optionally LLM-enhanced), and offers configurable table (HTML/image) and formula (MathML/SVG/image) rendering. Runs fully offline as of v1.0.0.
PythonPure-Python CLI (companion to pypdf) with commands including 2-up/booklet page layout, cat (extract/merge pages), check-sign (verify signatures), compress/uncompress, extract-annotated-pages, extract-images, extract-links, extract-text, meta/pagemeta, rm (delete pages), rotate, sign, update-offsets (repair simple PDFs), and x2pdf (convert other formats to PDF pages).
PythonExtracts text (with layout preservation, tolerance settings, regex search, and word bounding boxes), detects and extracts tables (via ruling-line or text-alignment strategies), and provides low-level access to characters, lines, rectangles, curves, images, annotations, hyperlinks, and form fields, with page cropping/filtering, password-protected PDF support, and visual debugging (page-to-image rendering with overlay annotations, incl. Jupyter display). Does not generate, modify, or OCR PDFs.
PythonConverts PDFs, images, PPTX, DOCX, XLSX, HTML, and EPUB to Markdown, JSON, HTML, or chunks, preserving reading order: reconstructs tables (heuristics with VLM fallback for complex cases), recognizes math/equations as LaTeX, extracts and saves images, performs multilingual OCR via the Surya VLM, strips headers/footers/artifacts, and can optionally use an LLM to improve accuracy.
PythonReads and writes PDFs: subset/merge/rotate pages, modify metadata, build reusable Form XObjects, N-up and booklet layouts, watermarking (overlay/underlay), image and Form-XObject extraction, poster-sized output, and splitting 2-up PDFs; integrates with ReportLab (embedding existing PDF content into newly generated documents) and rst2pdf. No encryption/decryption support, and limited compression-filter support (external tools like pdftk needed for full decompression).
Pure-Python PDF-1.7 parser/extraction library: text, images, HTML, or hOCR output with exact text location/font/color data; AcroForm and tagged-content extraction; outline/TOC extraction; embedded image extraction (JPG, PNG, TIFF, JBIG2, bitmaps); CJK and vertical-writing support; Type1/TrueType/Type3/CID fonts; RC4/AES decryption; and decoding of ASCIIHex/ASCII85/LZW/Flate/RunLength/CCITTFax compression filters.
PythonPython bindings for MuPDF covering text extraction (plain, rich dictionary with font/size/color/bbox, HTML/XML, raw blocks, table-to-Markdown); embedded image extraction and high-DPI page rendering to Pixmaps; Tesseract-based OCR (100+ languages); reading/writing annotations (highlights, notes, stamps, ink) and redactions (with permanent apply); AcroForm reading and filling; page insert/delete/reorder, merge/split, and metadata editing; PDF creation and Markdown-to-PDF conversion; password protection/RC4/AES encryption; hyperlink and cross-reference handling; and outline/bookmark read-write.
PythonConverts PDF, DOCX, PPTX, XLSX, images, and web pages into Markdown or JSON: strips headers/footers/page numbers while preserving structure, converts formulas to LaTeX and tables to HTML, OCRs scanned/garbled PDFs in 109 languages, handles single/multi-column and complex layouts (incl. cross-page table merging), and extracts images with captions. Offers CLI, FastAPI, and Gradio WebUI, plus Python/Go/TypeScript SDKs; builds on PDF-Extract-Kit's models.
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.
RubyRuby-GNOME project's binding of poppler-glib, exposing Poppler's PDF rendering/parsing capabilities (text/image extraction, rendering, metadata) to Ruby. Requires the system poppler-glib library.
ScalaExtracts figures, tables, captions, figure names/numbers, section titles, and in-figure text from scholarly (computer science) PDFs, with page location and bounding boxes; renders extracted figures as raster (PNG/JPEG) or vector (SVG/PS/EPS, via pdftocairo) images; supports multi-threaded batch processing and includes debugging visualization tools.
