File PDF is a browser-based toolkit for PDF tasks including converting, merging, compressing, splitting, editing, signing and protecting files. The site states that processing happens client-side, so documents remain on the user's device and are not uploaded to a server. It also describes no signup requirement, unlimited use and batch processing.
BreezePDF is a PDF editor that runs in the browser or locally on a desktop. It provides functions for adding text, signatures, form fields and images, and for merging, splitting, reordering and password-protecting PDFs. It also supports export to DOCX and CSV. Files are processed locally and are not uploaded to servers.
PDFEncrypt is a free, open-source native Windows app that encrypts PDF files using standard PDF encryption algorithms. Users specify a password required to open the document along with options and permissions for the PDF. Encryption runs locally on the Windows PC rather than uploading files to a third-party server. The app uses the iTextPDF library and is released under the AGPL license.
iLovePDF is an online service for working with PDF files that offers tools for merging, splitting, compressing, converting, rotating, unlocking and watermarking PDFs, among other tasks. The service has been available since 2010, and mobile and desktop applications are also offered.
Rare2PDF is a free online converter that turns specialized files into PDF, including Jupyter Notebooks, LaTeX documents, Markdown files and academic citations such as RIS and EndNote files. It lists over 20 converters, requires no registration or installation, and states that uploads are deleted within two hours.
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. Documentation covers several document and image APIs and client libraries.
