About Toolstack

Toolstack is a free online toolbox: 100+ tools covering JSON and encoding, text, images and PDF, dates and time, units, and everyday calculations. No account is required.

How Toolstack is built

• Process tool input in the browser whenever possible, without sending it to a server.
• Give every tool a stable URL for bookmarks, sharing, and search indexing.
• Keep the site fast, lightweight, and usable on desktop and mobile.

Current scope

Almost every tool runs locally in your browser and your files never leave your device. Two exceptions: comments (you sign in with GitHub and comments are stored on the server) and Image to Text / OCR (the image is uploaded and forwarded to an OCR provider; the server does not store it). Toolstack does not provide cloud workspaces or online code execution.
