Free, private, browser-based tools and games for everyone — no sign-up, no upload, no limits.
Plix.Tools is a free, independent collection of browser-based utility tools and casual games available at https://plix.tools. It covers six categories: image processing and PDF conversion, everyday calculators, content generators, developer tools, productivity utilities and browser games — 44 tools in total.
Every tool on the site runs entirely within your web browser using modern JavaScript APIs — the Canvas API for image operations, the Web Crypto API for hashing and encryption, the File API for local file access and the Intl API for date, number and currency formatting. Because all computation happens on your device, your files and data are never transmitted to any server. This is not a marketing promise — it is a technical constraint enforced by the site's architecture. The web server only serves static HTML, CSS and JavaScript files; there is no server-side code and no database.
The site is operated by an independent developer and is supported entirely by display advertising (Google AdSense). There are no subscription fees, premium tiers, paywalls, watermarks or account requirements. Every tool is free to use without limit.
Most free online tools fall into one of two traps: they either require you to upload sensitive files to an unknown server, or they push you to create an account and subscribe before you can use the basic features. Plix.Tools was built to solve both problems at once.
Modern browsers are remarkably powerful. A browser can compress a 5 MB JPEG to under 500 KB in milliseconds, generate a SHA-256 hash of any text without any network request, run a 2048 puzzle game or a full Sudoku engine, convert binary to hexadecimal, calculate compound interest amortisation schedules, and generate cryptographically random UUIDs — all without sending a single byte to a remote server. We built Plix.Tools to make these browser capabilities easily accessible through clean, reliable interfaces.
The tools we include are chosen based on real-world utility: tasks that professionals and everyday users regularly need to do but that currently require either paid desktop software, file uploads to third-party services, or complex command-line tools. Our goal is to make each of those tasks faster and more private.
Plix.Tools is a pure static site — no build system, no framework, no server-side rendering. Each tool is a self-contained HTML file that loads a shared stylesheet and a small shared JavaScript utility file. The tool logic itself is written in plain JavaScript, relying on well-supported browser APIs rather than third-party libraries wherever possible.
Image tools use the HTML5 Canvas API to decode, manipulate and re-encode images client-side. The browser's built-in JPEG encoder handles compression; PNG output uses lossless encoding. No files are ever read by our code in any other context.
Cryptographic tools — the hash generator and the AES encryption tool — use the window.crypto.subtle API, which is part of the Web Cryptography standard. This means the same cryptographic primitives used by secure HTTPS connections are used by our tools.
Developer and productivity tools (JSON formatter, regex tester, unit converter, timestamp converter, etc.) are pure JavaScript logic with no external dependencies. Calculators implement standard financial and scientific formulas (compound interest amortisation, BMI classification per WHO standards, age calculation using UTC date arithmetic). All formulas and their sources are documented in each tool's help section.
Privacy is not an afterthought at Plix.Tools — it is the core architectural principle. When you compress an image, convert a file, encrypt some text or run a regex, that data never touches our servers because our servers have no capability to receive it. We serve static files over HTTPS via Cloudflare Pages; that is the extent of our infrastructure.
We use Google Analytics to understand which tools are most useful and how users navigate the site, and Google AdSense to serve advertisements that fund the project. Both are subject to our Privacy Policy and our cookie consent banner, which follows Google Consent Mode v2 — meaning no tracking cookies are set unless you explicitly consent.
The only personal data we ever receive is what you voluntarily submit through the Contact form — your name, email and message. That data is used only to respond to your enquiry.
All processing happens in your browser using standard Web APIs. We have zero server-side access to your files or inputs.
Every tool is free with no hidden tiers. The site is funded by non-intrusive Google AdSense advertising.
No server round-trips, no upload progress bars. Computation runs locally, so results appear in milliseconds.
Tools are tested across Chrome, Firefox, Safari and Edge. New tools are added regularly based on user suggestions.
Every tool works directly in your browser — desktop and mobile. No app download, no browser extension required.
Full light and dark theme support across all 44 tools. Your preference is saved locally and respected on every visit.
All tools are free, instant, and private. No sign-up required.
