Does not replace every AI feature, mobile app or existing-paragraph reflow editor.
Windows 10/11 desktop. No claim of full Acrobat text editing or hosted signature parity. For UPDF: create, merge, split, reorder, compress and OCR PDFs locally on Windows. Free for private and business use without a usage quota. This replaces document-processing tasks, not full editing/reflow of existing paragraphs, the UPDF AI assistant, mobile apps or cloud synchronisation. For PDF Candy: Merge, split, reorder, compress and OCR PDFs offline on Windows without hourly software quotas; free for private and business use. Your hardware limits capacity. Not the complete PDF Candy web conversion catalogue, existing-paragraph reflow editor or AI suite.
