About Swizztool

Swizztool is a free collection of 77 small tools for everyday jobs: counting words, merging PDFs, compressing images, formatting JSON, converting colors, and making social media mockups.

It is built and maintained in Austin, Texas by Bibesh Kc. The site launched in August 2026, and tools are added and improved based on what people search for and ask for.

Why it exists

Most free online tools ask you to upload your file to someone else's server, sign up for an account, or put up with a watermark. For a task that takes ten seconds, that's a poor trade, especially when the file is a contract, a client draft, or a private photo.

Swizztool takes the other approach. Each tool runs entirely in your browser, so your files and text never leave your device. There's nothing to install and no account to create.

How the tools work

When you open a tool, your browser downloads the code for it and does the work locally. PDF tools use the open-source pdf-lib and PDF.js libraries. Text recognition (OCR) uses Tesseract.js, which runs the recognition engine in your browser. Image tools use the browser's built-in canvas. Because nothing is uploaded, most tools also work on slow connections once the page has loaded.

The site is supported by ads, which is how the tools stay free. Read the privacy policy for exactly what the site does and doesn't collect.
