Nifty Utilities
100+ everyday tools that never upload your files
Nifty Utilities とは？
Nifty Utilities is a toolbox of 100+ free utilities that all run entirely in your browser — no upload, no sign-up, no watermarks, nothing stored. Convert HEIC to JPG, compress a photo to 100KB, merge PDFs, clean a messy CSV, generate a receipt, or take a quick IQ test. Because there's no server behind it, your files and data physically can't leave your device.
