Files

These tools handle the small, awkward jobs that usually mean opening a heavy application or trusting an unfamiliar upload form. The CSV viewer turns a wall of commas into a readable table and works out whether the file is comma, semicolon or tab separated. The file name cleaner takes a list of messy names and returns safe ones, with spaces replaced, accents stripped and the characters that break uploads and command lines removed. The MP3 converter extracts the audio from a video or re-encodes an audio file.

What they share is where the work happens. Each one processes your file inside the browser rather than sending it to a server, which matters most for exactly the files people hesitate over: a customer export, an unreleased recording, a folder of scanned documents. Nothing is uploaded, nothing is stored, and closing the tab ends it. The MP3 converter downloads its conversion engine once on first use, and even then your file itself never leaves the device.
