How they differ
RaptorPDF — the broadest all-in-one
RaptorPDF bundles the widest set of tools — text editing, annotation, signing, form filling, merge, split, compress, convert and password protection — into one browser editor, all processed locally so files never leave your device. It needs no signup to start, never adds a watermark, and its Pro plan is just $4.99/month. It's the best fit when you want one tool for everything without uploading or paying business prices.
LocalPDF — best for OCR
LocalPDF runs entirely on WebAssembly with zero bytes sent to servers, and covers edit, merge, split, compress, sign and convert. Its standout feature is built-in OCR for turning scanned pages into searchable text. If OCR is your priority, LocalPDF is an excellent local-first choice.
SimplePDF — simplest for forms & signing
SimplePDF has a very clean interface focused on filling forms, adding text and signing, with no watermark and no signup on its free individual tier. Its limitation is breadth and price: it doesn't focus on merge, split, compress or conversion, and its paid plans start at $99/month aimed at businesses and embedding.
CIB pdf standalone — privacy-focused utilities
CIB pdf standalone is a WebAssembly tool from German software company CIB with a strong privacy guarantee. Its free browser edition is a solid utility kit — merge, split, compress, convert images to PDF, rotate pages and password protect — though it's lighter on rich text editing and annotation than RaptorPDF.
