Wancai OfficeBox was once a hugely popular free office toolbox, but on 26 May 2026 the official service was fully retired. Even though the online service is down, the offline version integrates 60+ office mini-tools covering PDF processing, format conversion, OCR, screen recording, image editing and almost every daily office need; it still works forever free offline, and the experience is surprisingly good. Features: the offline build is a green portable version, no install, no network needed; on first launch you follow the official Wancai public account and wait for a verification code; 60+ practical mini-tools in every area; supports PDF to Word/Excel/PPT, merge, split, watermark, encrypt, plus universal conversion among documents, images, audio and video. Completely free; no future maintenance, but basically enough for daily use.
