Tool shelf/4 live

Little tools,
kept close.

Fast utilities that run on TLBX hardware. No uploads to someone else’s cloud, no upsells. Everything works without an account except the QR generator, the stock downloader and the short linker, which each need one so a thing has an owner.

Media Converter

Images, video & audio

Convert and resize images and videos, turn MP3, FLAC, WAV, OGG, Opus and M4A into each other, or pull a video's audio track out on its own. Simple stills run on this device; heavier work, including video and audio, goes to the processing server.

Transcription

Audio & video to text

Turn a recording into timestamped text, with or without speaker turns. Words appear while they are still being recognized, and the finished transcript downloads as text, subtitles or structured JSON.

PDF Toolkit

Merge, split, compress & edit

One workspace for eight PDF jobs: merge, split, rearrange, compress, edit, rotate, images to PDF and PDF to images. Everything runs in the tab, and files never leave the device.

QR Generator

Dynamic codes you can change

Make a QR code around a permanent short link: change the destination later without reprinting, protect it with a visitor password, set an expiry, or recover it within 30 days.

Link Shortener

Short links you control

Turn a long address into a short one you can change later: pick the code or let it choose, set an expiry, add a visitor password, attach your own domain, and see how many people opened it.

Temporary Shares

One link for a pile of files

Drop any mix of files and get one short link. Browse them, preview images and video, download everything as one ready-made ZIP, and let the whole thing delete itself.

New utilities get their own subdomain and a card on this shelf.

Downloads, conversion, transcription, PDF work and temporary shares stay open to everyone. The QR generator, the stock downloader and the short linker ask you to sign in; a QR code stays public to scan, stock never stores your media, and a short link stays public to open.
