Short, practical guides for getting the most out of ToolBench. Pick a category below to find how-to notes for the tools inside it — everything still runs locally in your browser, no sign-up required.
Every tool on ToolBench runs entirely client-side. That means when you open a PDF, image, or piece of text in a tool, it's processed directly in your browser's memory — it's never uploaded to a server, which is what makes the tools fast and keeps your files private. Closing the tab clears everything.
Most tools work the same basic way: choose or drop in your file (or paste your text), adjust any options, and download or copy the result. There's nothing to install and no account to create.
Merge, split, rotate, and extract from PDFs — processed locally in your browser.
