About HandyBench
HandyBench is a collection of small, single-purpose tools for jobs that come up constantly and shouldn't need an app install or an account: counting the words in a cover letter, working out a loan EMI, turning an iPhone HEIC photo into a JPG, merging two PDFs, or checking a page's meta tags before it goes live.
Your files stay on your device. The PDF, image, text, calculator and developer tools run as JavaScript in your browser. When you merge a PDF or compress a photo, the file is read and rewritten locally and never uploaded. Only the tools that have to reach the internet, such as the website checkers, DNS and WHOIS lookups, the currency rates and "What is my IP", go through our own server, and those only receive what the lookup needs, such as the URL or domain you enter.
Every tool comes with step-by-step instructions and answers to common questions. The most-used tools also explain how they work: the formula behind a calculator, the format rules behind a converter, worked examples and the limits worth knowing. For topics that need more room, the guides go deeper, for example how EMI is calculated, compressing images for the web and gross vs net pay.
