Who Is Behind This Site

My name is ASSOGANE Pouarassane. I have been working as a software developer since 1994 — more than 30 years of building applications, tools, and systems across a wide range of technologies and platforms.

Over the decades, I have worked with low-level C and C++, server-side Java and PHP, and now modern TypeScript and JavaScript frameworks. I started FreeUtilityTools as a personal project to apply modern browser APIs — Canvas, WebAssembly, File API — to practical everyday problems that millions of people face: compressing a photo for a visa application, merging a few PDF documents, or converting an image for a website.

Every tool on this site is designed, coded, and maintained by me. When I say files never leave your device, that is not marketing copy — it is the architecture. There is no backend file-processing server because I chose not to build one. Processing happens entirely in your browser, using the same Web APIs that power the modern web.

Why I Built This

The frustration was simple: every tool I found for compressing an image or merging PDFs either required creating an account, uploaded files to a server (often without being transparent about it), added watermarks, or limited free usage to a handful of files per day.

As a developer, I knew these tasks could be done entirely in the browser. The HTML5 Canvas API has supported image manipulation since 2011. PDF.js and WebAssembly have made PDF processing in the browser viable since 2017. The technology was there — someone just needed to package it into clean, fast, free tools without the usual limitations.

So I built FreeUtilityTools. The goal is straightforward: give everyone access to the same file-processing capabilities that used to require expensive desktop software or cloud subscriptions, for free, with complete privacy, and without friction.

What We Offer

Image Compression

Compress images to exact sizes — 20 KB, 50 KB, 100 KB, 200 KB — for forms, passports, email, WhatsApp, Instagram, and more.

Image Conversion

Convert PNG to JPG, resize images to exact dimensions, or export to WebP for faster web pages.

PDF Compression

Reduce PDF file sizes with Screen, eBook, and Print quality presets while keeping files fully readable.

PDF Manipulation

Merge PDFs, split pages, convert PDF to Word / Excel / PowerPoint, or turn images into a PDF — all in the browser.

Privacy Guarantees

Privacy is not an afterthought on this site — it is the architecture. When you open a file in any tool on FreeUtilityTools, the file is read into your browser's memory using the browser's built-in File API. All processing (compression, conversion, merging, splitting) is performed locally using JavaScript running in your browser tab. The result is written back to browser memory and offered to you as a download.

At no point is any data transmitted over the network to our servers or any third-party service. You can verify this by opening your browser's Network tab (DevTools → Network) and confirming that no upload requests are made when you process a file.

We do not set tracking cookies, we do not run analytics that identify individual users, and we do not sell or share any data. The only external service present on the site is Google AdSense, which serves display advertisements to cover hosting costs.

Our Principles

  • Privacy first. Your files are processed locally in your browser. We have no access to them — ever.
  • Always free. Every tool on this site is free to use with no limits, no watermarks, and no paywalls.
  • No signup required. Open a tool, use it, download your file. No account, no email address needed.
  • No software to install. Everything runs in your browser using modern Web APIs — on desktop and mobile.
  • Transparent about limitations. If a tool cannot do something (e.g., password-protected PDFs), we say so clearly.

Technical Foundation

FreeUtilityTools is built with Next.js 14 and deployed as a fully static site. There is no server-side rendering at request time — every page is pre-rendered at build time, which means fast load times globally without any per-request compute cost.

The image tools use the HTML5 Canvas API with a binary-search quality algorithm to hit exact target file sizes. The PDF tools use PDF.js (Mozilla's open-source PDF renderer) and pdf-lib for creation and manipulation — both running entirely in the browser via WebAssembly and JavaScript.
