Stirling PDF is an innovative and powerful web-based application developed to cater to all your PDF manipulation needs. Originally created as a ChatGPT-made application, it has since evolved, offering a broad array of features for handling PDF files. It can carry out functions like splitting, merging, converting, reorganizing, adding images, rotating, compressing among others all from a locally hosted interface.
Its list of key features includes an interactive GUI that makes it user-friendly when merging, splitting or rotating PDFs. Users can effortlessly split large PDF files into multiple smaller ones based on specified page numbers or extract all pages as individual files. You can also merge various PDFs into one file and convert these files into images or vice versa. Stirling PDF allows you to reorganize pages in whatever order you prefer and add or generate signatures as well.
Further enhancing its versatility are capabilities such as repairing damaged PDFs and detecting blank pages for removal. You can compare two documents and highlight textual differences. Other features include adding watermarks to your documents for ownership purposes, setting up passwords for added security and adjusting permissions on the file level. For further convenience, the software supports the extraction of images from a PDF and executing OCR on it using OCRMyPDF.
To round up its impressive set of features is an API for integration with external scripts, dark mode support for eye comfort during long hours of operation and custom download options alongside parallel file processing which makes dealing with multiple files more efficient.
