About Toolsnest

Toolsnest is a growing collection of fast, private, browser-based tools — a single home where all your everyday file, image, document and developer needs live. Merge and sign PDFs, convert and compress images, format code and data, generate passwords and QR codes, crunch numbers, and more.

The idea is simple: the tools you reach for every day, gathered in one tidy nest — and built so your files never leave your device. Everything runs locally in your browser, which keeps Toolsnest instant, private and free.

Private by design

Most online tools upload your file to a server to process it. Toolsnest does the opposite: the work happens on your own computer using the browser you already have. That means a contract, a bank statement, a family photo or a snippet of source code never leaves your machine. There is no account to create, no file stored in the cloud, and nothing for us to leak. It is also why the tools feel instant — there is no upload wait and no server round-trip.

What’s inside

Toolsnest spans six main areas: PDF tools for merging, splitting, compressing, converting and signing documents; image tools for converting, resizing, cropping and compressing pictures; developer tools for formatting and validating JSON, XML, YAML, SQL and more; text tools for cleaning, counting and transforming text; colour tools for picking, converting and generating palettes; and a large set of calculators covering finance, health, maths, dates and unit conversions. New tools are added regularly.

Free, for everyone

Every tool is free to use for any purpose, personal or commercial, with no trial limits and no watermarks. If a tool is missing or could work better, we would love to hear from you on the contact page — Toolsnest grows around what people actually need.
