Command-line PDF manipulation toolkit: split, merge, and extract pages while preserving bookmarks; encrypt/decrypt (AES 128/256); scale, rotate, crop, and flip pages; stamp text, watermarks, and page numbers; manage annotations, metadata, and file attachments; rasterize pages to images; and produce PDF/UA-tagged output.
Android PDF toolkit centered on creating PDFs from camera or gallery images (plus converting plain text files to PDF), alongside managing existing PDFs: merge, split, compress, remove/rearrange/rotate pages, extract images, and encrypt/decrypt. Aimed at the common mobile use case of turning photographed documents or receipts into a shareable PDF, with the page-management tools included as a secondary, more general-purpose capability.
PythonSmall 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.
C#Source code of the well-known PDFCreator from pdfforge, a free virtual-printer application: install it once and any application's own Print dialog can output directly to PDF. Supports merging and reordering pages, password and digital-signature protection, PDF/A archival compliance, custom cover pages, and automated post-processing actions (FTP upload, email delivery, custom scripting) triggered on every conversion. Widely used as a default 'print to PDF' tool on Windows.
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).
Pythonic 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.
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.
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.
UTF-8/RTL text with TrueType/OpenType/Type1/CID-0 font support and subsetting; HTML/CSS and SVG rendering with multi-column layouts, headers/footers, bookmarks, and TOC; JPEG/PNG/SVG images (plus GIF/BMP/TIFF/etc. via GD); RC4/AES-256 encryption; PAdES/PKCS#7 digital signatures with RFC 3161 TSA timestamps and LTV; PDF/A, PDF/X, and PDF/UA compliance modes; page import/reordering; AcroForm fields; and companion-package barcode support.
GoComprehensive Go PDF toolkit for reading, writing, and processing PDFs: text/image/table extraction, merging/splitting/rotating/rearranging pages, form creation and filling, encryption/decryption, digital signing, watermarking, and image-to-PDF conversion.
Go 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.
