Private browser tools for repetitive file work

- supporters
FileNest Worktools is a privacy-first browser toolkit for repetitive file tasks.
It combines batch file renaming and ordering, local image OCR, JPG/PNG/WebP conversion and resizing, PDF merge and split workflows, CSV/TSV/JSON conversion, document creation, and duplicate-file detection in one browser-based workspace.
For the current browser-local tools, file contents are processed on the user's device rather than uploaded to a remote conversion server. Many workflows also provide previews, conflict checks, or output details before download, while original files remain unchanged.
FileNest is aimed at office workers, students, teachers, freelancers, creators, and anyone who regularly needs quick file utilities without installing separate software for every small task. The interface is available in English and Chinese.
