It's a Windows desktop app that works entirely offline — no cloud upload required — making it ideal for sensitive documents. It handles text editing, annotation, merging, splitting, compression, OCR, and PDF conversion. The app is lightweight enough for low-spec PCs and completely free with no paid tier.

PDFgear is the most recommended free Adobe Acrobat alternative, offering text editing, annotation, file merging, link embedding, image insertion, and PDF conversion — all completely free.

LibreOffice Draw
LibreOffice Draw (part of the free LibreOffice suite) can open, edit, and export PDFs. It's particularly good for form editing and graphic-heavy PDFs. Text editing is more limited than dedicated PDF editors, but for basic edits it's completely free across Windows, Mac, and Linux.

PDFgear is the best cross-platform choice (Windows and Mac) with an AI summarization feature that helps users quickly understand long documents.
If OCR is a priority (converting scanned documents to searchable/editable text),PDF-XChange Editor has the best free OCR implementation. For organizations that process sensitive documents and can't afford to upload files to cloud services,Stirling PDF as a self-hosted Docker deployment is the privacy-compliant choice.
For occasional use — filling out a form, annotating a contract, or merging a few PDFs —PDFescape requires no installation at all. Just open the browser, upload your PDF, and edit.
