About One Man Army

One Man Army (OMA) is a growing collection of small, free online tools. Each tool lives at its own URL and solves exactly one problem — no bloat, no sign-up required.

The philosophy is simple: one arsenal, all missions. Instead of bloated apps that do everything poorly, OMA ships focused utilities — a word counter, a JSON formatter, an image compressor — each built to do its job well.

The site is built and maintained as a personal project to create useful utilities and practice web design and development. All tools run in your browser whenever possible, so your data stays on your device.

Popular tools to start with:

• Word Counter — Count words, characters, sentences, and reading time instantly.
• JSON Formatter — Format, validate, and minify JSON in your browser.
• Image Compressor — Resize and compress images without uploading to a server.
• PDF Merge & Split — Merge multiple PDFs or extract pages — all in your browser.
