What is Toools.cloud?
Toools.cloud is a free collection of online utilities designed to handle everyday tasks — from editing images and managing PDFs to formatting text, generating barcodes, and working with developer tools. The site currently offers over 39 tools organized across 8 categories.
Privacy-First Design
Every tool on Toools.cloud runs entirely in your browser. Your files, images, text, and data are processed locally on your device using client-side JavaScript. Nothing is uploaded to a server. Nothing is stored. This means your data stays completely private — always.
This architecture was a deliberate choice from the very beginning. There are plenty of online tools that process your files on their servers, but that requires trusting a third party with potentially sensitive content. Toools.cloud eliminates that concern entirely.
How It Works
The site is built with Next.js and React, using static site generation for fast page loads. Each tool is a self-contained component that uses browser APIs and JavaScript libraries to do its work:
- Image tools use the Canvas API and specialized compression libraries for resizing, cropping, filtering, and compressing photos.
- PDF tools use pdf-lib and pdfjs-dist to split, merge, encrypt, and convert PDF files without server-side processing.
- Coding tools leverage Monaco Editor (the engine behind VS Code) for diff checking, and built-in browser APIs for Base64 encoding and URL manipulation.
- Text tools use Unicode transformations and text-processing algorithms for word counting, ASCII art generation, and punctuation correction.
Design Philosophy
Toools.cloud follows the Unix philosophy: each tool does one thing and does it well. The interface is kept simple and focused — no accounts, no sign-ups, no paywalls, no usage limits. Open the tool, use it, and move on.
Who Built This?
Toools.cloud is built and maintained by Arnon Eilat, a software developer focused on creating useful, accessible web tools. The project started as a way to build tools that respect user privacy while remaining genuinely useful for everyday tasks.
