JPedal

manipulating PDF documents with the JPedal PdfManipulator class, where the official Manipulate PDF files in Java page, labelled v2026.07, says JPedal provides a PDF Manipulator class for easy manipulation, editing, and creation of PDF files, documents loading a document from a File, byte array, InputStream or URL including password protected files, creating a new empty document, writing the document to a File, byte array or OutputStream, and applying manipulations that include adding text, images, shapes and annotations, adding, copying, removing, moving, swapping, reversing and reordering pages, rescaling pages and page content, cropping and rotating pages, embedding and attaching files, isolating and n-up pages, adding and removing bookmarks, setting document info, getting setting and removing metadata, setting the initial view, generating a table of contents, page and document queries, and sanitising or optimising operations that include flattening layers, redacting text, removing JavaScript, embedded files, hyperlinks, metadata, annotations, initial view and blank pages, rewriting streams, downsampling images and optimising colour palettes, with no operation among the sixty six documented headings that edits or replaces existing text, existing images or existing layout

viewing PDF files with the JPedal Java viewer, where the official documentation says JPedal includes a comprehensive PDF viewer that uses Swing and optionally JavaFX, that the Viewer is customizable and written in Java but can be run from other languages or the command line, that JavaFX is an optional plugin used to enable the page flow mode, and that a viewer is opened through the Viewer class with setupViewer and the OPENFILE command or by running java -jar jpedal.jar with the view option, with the product page listing single page and continuous page display, document navigation, text search, zoom, scale and rotate of pages, a customisable interface and look and feel, and image viewing capabilities, in a 100 percent Java viewer running on Java 17 and later

extracting content from PDF files with the JPedal Java library, where the official extraction documentation says JPedal is a pure Java PDF library for extracting text, images and metadata, and its capability table lists word list extraction returning each word with bounding box coordinates, unstructured text as seen on the page, structured text as a logical hierarchy of headings, paragraphs, tables and lists, text search returning the page coordinates of all matches for a search string, images in JPEG, JPEG2000, JBIG2 and PNG and other embedded formats, and metadata covering page count, dimensions, author, date, XMP and DocInfo fields, with extraction of unstructured text from a specified rectangular area, document outline extraction, and a structured text extractor whose file output modes include EPUB, HTML, JSON, Markdown, XML and YAML, on Java 17 or later with no third party dependencies

converting PDF documents to other formats with the JPedal Java library, where the official Convert PDF to Image documentation says JPedal converts PDF pages to raster images in pure Java, writing output directly to AVIF, BMP, GIF, HEIC, JPEG, JPEG2000, PNG, TIFF or WEBP or returning a Java BufferedImage for in-memory processing, that all conversion methods accept either a float scaling value or a width and height integer array to constrain output dimensions and that the fit to size option preserves aspect ratio, and that the BufferedImage path creates no temporary files, and where the Convert PDF to PDF/A-3 documentation says the PdfA3Converter class converts PDF files into PDF/A-3 files from Java or the command line, that only conformance level B is currently supported, and that the conversion result lists any issues and any lossy changes made to fix them, with a minimum Java version of 17 and a legacy Java 8 build from August 2024 available

digitally signing PDF files with the JPedal Java library, where the official Digitally Sign PDF files documentation, shown at version 2024.11, says JPedal supports PAdES Baseline Level B signatures and requires a PKCS #12 keystore containing the private key and X.509 certificate, a valid certificate, a certificate signature algorithm of SHA256 with RSA and a private key usage that includes digitalSignature, and documents the PdfSigner signPdf static method taking the input and output file locations, the keystore password, the keystore file, a signer name, a location, a reason and a document access permission level, where P1 allows no changes otherwise the signature is invalidated, P2 allows no changes except filling in forms, instantiating page templates and signing, and P3 includes those plus annotation creation, deletion and modification, and where the page contains no wording about timestamps, timestamp authorities, signature verification or a visible signature appearance

protecting PDF files with a password using the JPedal Java library, where the official Encrypt PDF Files in Java documentation, shown at version 2026.05, says PDF encryption restricts access to document content so that only recipients with the correct password can open or read a file, that JPedal provides an API to apply password protection and configure encryption settings programmatically through the PdfManipulator class, that a document is loaded and written with writeDocument taking the output document and a password which sets the password required to open the document, with byte array and OutputStream versions of the method, and that additional encryption behaviour is configured through EncryptionSettings before writing, the documented example being whether document metadata should be encrypted, while the page names no encryption algorithm, key length, owner password or permission flags

merging PDF files with the JPedal Java library, where the official Merge PDF files documentation, shown at version 2025.05, says JPedal merges PDFs into a single new file containing all the pages from the provided files and leaves the original files untouched, that the PdfMerge command line tool accepts input files and options in any order while merging the files in the order they appear in the arguments with the last argument always being the output file, and that the PdfMerge Java API offers static convenience methods for merging two files or an array of files into one, with overloads taking a password for each input and overloads taking a list of merge options such as the interleave option, while the merge page itself states nothing about bookmarks or metadata, and where the manipulation index separately says the merged output preserves fonts, images and page structure from each input file
