Toolsbox – 688+ Free Online Tools

About

Toolsbox is a free browser extension that gives you one-click access to hundreds of online tools without interrupting your workflow.

Click the Toolsbox icon in your toolbar, type what you're looking for, and open any tool instantly. Whether you need to convert a file, format some code, check a colour value, or generate a password, it's right there.

SEARCH ACROSS 688+ TOOLS
Start typing and results appear immediately from a local index — no network requests, no waiting. Find any tool by name or keyword in under a second.

FEATURED TOOLS FROM EVERY CATEGORY
The popup highlights the most popular tool from each category so your most-used tools are always visible. Includes tools for working with PDFs, images, audio, colours, text, code, and more.

RECENT TOOLS HISTORY
Your last five opened tools are saved locally so you can jump back to them with a single click.

ADDRESS BAR SHORTCUT
Type "tb" in Chrome's address bar followed by any search term to find and open a tool without clicking the extension icon.

RIGHT-CLICK SHORTCUTS
Select text on any page, right-click, and choose from shortcuts that open the relevant tool — such as a word counter, JSON formatter, or URL encoder — directly on toolsbox.io.

PRIVATE BY DEFAULT
Nothing is sent to any server. Your recent tools are stored only in your browser's local storage. No account required.
All tools open on toolsbox.io and run entirely in your browser.
