Command-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#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.
Fluent-API PDF generation library for .NET: page layout, headers/footers, tables, columns, sections, watermarks, text/fonts/colors/backgrounds/borders, images, SVG, alignment/padding/scaling/rotation/layering, loops/conditionals/reusable components for data-driven documents, merging, encryption, metadata, page extraction, and PDF/A, PDF/UA, and EN 16931 (e-invoicing) compliance.
GoGo library for generating PDFs: Unicode/CJK subfont text with kerning, alignment, sub/superscript, RGB/CMYK color; vector shapes (lines, ovals, rounded rectangles, polygons, curves); JPG/PNG images with masking; password protection with permissions; headers/footers, links, transparency/blend modes; table layout; page rotation; and importing/reusing existing PDF pages as templates.
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.
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.
JavaFree, cross-platform desktop app (JavaFX, self-contained with bundled JRE since v4) for splitting, merging, mixing, rotating, and extracting pages from PDF files.
JavaScriptDisplays existing PDFs in React apps (built on PDF.js): renders pages via `<Document>`/`<Page>` with canvas, custom, or no rendering; shows outline/table of contents and thumbnails; selectable text and annotation/link layers; form rendering; page rotation and zoom; password-protected PDF handling; JPEG2000 and non-Latin (cMap) support. (Complementary to @react-pdf/renderer, which creates PDFs rather than displaying them.)
JavaScriptNode.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.
JavaScriptVue 2 component for displaying PDFs from URLs, file paths, or binary data: page navigation, 90°-increment rotation, password-protected PDF handling, per-page or range printing, load-progress tracking, text extraction/selection, clickable internal links, and rendering multiple page instances at once.
Perl module for building PDFs by reusing existing pages as templates/backgrounds: adds positioned/rotated text, embeds JPEG images, hyperlinks, and raw PDF operators; supports built-in and embedded TrueType (UTF-8) fonts, hierarchical bookmarks, attached/embedded JavaScript actions, form field value assignment, and content stream compression.
PerlPerl module (built on PDF::Reuse) for generating multi-page PDFs: text with font/size/color control, 14 built-in fonts plus custom TTF embedding (with Unicode), alignment and rotation, regex-based text formatting, JPEG image embedding, importing pages from existing PDFs as templates, horizontal rules, raw content streams, and auto-sized tables with headers, borders, padding, and page-overflow handling.
PerlPure-Perl (PDF 1.0–1.3), dependency-free module for creating PDFs: multi-page documents with standard paper sizes and page rotation/crop/bleed/trim boxes; built-in PostScript fonts with Unicode/international character support; lines, GIF/JPEG image embedding, and clickable URI link annotations; hierarchical outline/table of contents; and document metadata.
Converts XML (or Markdown) documents to PDF or images (JPEG/PNG via GD/Imagick/Gmagick) with HTML-like tags (div, p, table, headings, lists, images, links); supports auto-breakable/fixed pages, multi-column layouts, headers/footers/watermarks, page numbering, metadata, internal/external links, bookmarks, sticky notes, barcodes (via Zend), simple pie charts, borders, backgrounds, rotation/transparency, and stylesheets; usable via web or CLI, with Symfony2 integration.
Small python-gtk application, which helps the user to merge or split PDF documents and rotate, crop and rearrange their pages using an interactive and intuitive graphical interface. A GUI front-end for pikepdf; can also import images into a PDF when img2pdf is installed.
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.
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).
PythonAdds a searchable OCR text layer beneath page images and produces a validated PDF/A file: deskews crooked pages, optionally cleans images pre-OCR, optimizes/compresses images, recognizes 100+ languages via Tesseract, rotates misrotated pages, edits output metadata, parallelizes across CPU cores, and processes multi-thousand-page files in place.
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).
Toolkit for extracting tabular data from OCR'd ('sandwich') PDFs already converted to pdf2xml format: splits scanned double pages, detects lines via image processing, corrects page skew/rotation, clusters lines/text into table columns and rows, and exports to pandas DataFrames (CSV, Excel, etc.). Not an OCR tool itself — requires pre-OCR'd input from Tesseract/ABBYY; the authors recommend trying `pdftotext` first.
