About Us

Who we are

adigitools.com is a collection of free online tools made for freelancers, small business owners, online sellers and anyone who needs a quick, reliable answer without learning complicated software. We started with a simple observation: many everyday tasks, like compressing a picture, making an invoice or working out the return on an advertisement, should take minutes, but people often waste hours searching, signing up for trials and fighting with settings. Our goal is to make those tasks short, clear and free.

What we do

We design, build and maintain tools in seven areas: image preparation, business administration, contracts, marketing calculation, web security, Etsy selling and Amazon KDP publishing. Each tool is paired with a plain-language guide that explains what the result means, which mistakes to avoid and what to do next. We want you to leave with a finished task and a better understanding, not just a number on a screen.

Our principles

• Useful first: a tool must solve a real problem completely before we publish it.
• Private by design: wherever possible, processing happens in your browser. Your files, passwords and figures are not uploaded.
• Clear and honest: we explain formulas, state limits and say when a result is an estimate.
• Mobile friendly: most visitors use a phone, so every page is built for small screens first.
• Accessible to everyone: the site supports multiple languages, readable text and keyboard navigation.
• No clutter: advertising is limited and clearly separated from content.

How the tools are made

Every tool goes through the same steps. We define the user's goal, build the simplest interface that reaches it, test the maths and the edge cases and write a guide with instructions, examples and answers to common questions. We check the tools on current phones and desktop browsers. When rules, prices or platform policies change, we update the pages. We do not claim that our tools are perfect, and we welcome corrections.

Who we serve

Freelancers use our invoice, rate and project tools to run their practice. Small businesses use the payroll, contract and marketing calculators to decide with real numbers. Sellers on Etsy and Amazon KDP use the listing, mockup and book helpers to prepare products faster. Website owners use the security tools to find simple problems early. Students and creators use the image tools every day.

How we earn

The tools are free. To cover hosting and development, some pages show advertising from third parties. Ads are labelled, kept away from interactive controls and never change what the tools calculate. Read the privacy policy to learn how advertising and cookies work.

Independence and trust

We are an independent publisher. We are not affiliated with the marketplaces, internet providers or software companies named on our pages, and their names are used only to describe compatibility or purpose. Results from our tools are information, not professional advice. Please read the disclaimer and the terms of service.

Get in touch

We read every message. If you have a question, found an error or want to suggest a tool, use the contact page. Browse all tools in the tools directory or start with the blog for guides.

Our story and where we are going

The first tools on this site were built to answer questions we kept hearing from freelancers and sellers: how do I make my product photo look clean, what should I charge, is this campaign worth it? Each tool grew from a real task. Over time we added guides, a multilingual interface and more categories. In the future we plan to add more languages, more tools for sellers and creators and more tutorials that combine several tools into complete workflows.

Quality and updates

We review tool pages when platforms, prices or rules change and test the main tools after each update. Feedback from visitors drives many improvements, so thank you to everyone who writes in.
