BentoPDF is a free, open-source online PDF toolkit that processes files locally in the browser using WebAssembly, so files are not uploaded. It offers over 100 tools for merging, splitting, compressing, converting, editing, annotating, signing and filling PDFs, and is described as self-hostable with offline OCR.
pdfgrep is a free command-line tool that searches for patterns in PDF files and prints matching lines. It aims to be mostly compatible with GNU grep, supporting options such as -r, -i, -n, and -c, with extended regular expressions by default and page rather than line numbering for -n.
A web tool for editing PDF bookmarks. Users select a PDF, add or edit chapter, section and subsection bookmarks, and import bookmarks via keyboard shortcuts. It also includes a merge feature where files are dragged to reorder them before merging.
Free online document converter that converts Word, Excel, PowerPoint and image files such as TIF, JPG and HEIC to PDF, PDF/A or image formats. Files are uploaded through the browser with no installation required. A separate desktop tool, docuPrinter Pro, is offered for creating PDF or image files from Windows applications with a print menu.
wkhtmltopdf and wkhtmltoimage are open source command line tools that render HTML into PDF and image formats using the Qt WebKit rendering engine. They run headless without a display or display service. A C library, libwkhtmltox, offers bindings for PDF and image conversion.
PDFCrowd provides APIs and integrations for converting HTML, URLs, and web pages to PDF. It offers an HTML to PDF API, WordPress plugin, WebSave as PDF, and automation integrations including Zapier and Make, along with free online tools.
