About ToolboxMzansi

ToolboxMzansi is a set of small, useful utilities. They are free, fast and have no sign-up, adverts inside the tools or file limits imposed by a server, because there is no server involved.

Why in the browser?

Your text, passwords and files are processed by your own device. We never receive them. That is safer for anything private, and it means the tools keep working even on a slow connection once the page has loaded.

Passwords and randomness

The password, passphrase and UUID generators use your browser’s built-in secure random number generator. Nothing generated is saved, logged or sent.

What is in the toolbox

Text. Count words with the word counter, character counter and sentence counter, change capitals with the case converter, tidy text with the text cleaner and the duplicate line remover, and spot changes with the text compare tool.
PDF and images. Merge, split, extract and rotate PDFs, turn pictures into a PDF with images to PDF, and resize, crop, compress or convert pictures.
Converters. Length, area, volume, weight, temperature, time and storage converters, plus a percentage calculator, an age calculator and a date difference calculator.
Generators. A password generator, a passphrase generator, a QR code generator, a UUID generator and a lorem ipsum generator.

Limits to know

Because everything runs on your device, very large files can be slow, and a phone with little memory may struggle with a big PDF or a stack of photos. If a tool stops, try fewer or smaller files. Your original files are never changed, so you can try again.
