A Chinese-language collection of free utilities for PDFs, images, audio, video, files, text, calculations, security, and developer workflows.

Landing page captured for the 2026-09-04 issue.

Field notes

Chaos Lab groups document, media, coding, security, and household utilities behind a category-based directory rather than a single-purpose workflow. Its index includes concrete operations such as extracting PDF pages, reading image EXIF data, hiding text in pixels with LSB steganography, generating 20-plus barcode formats, and converting CSV to JSON. The homepage also exposes a ranked list with usage counts, while repeatedly stating that file handling occurs locally in the browser.
