Your All-in-One Online Toolbox
MamaTool brings together thirty practical utilities in one clean, fast website. Instead of searching for a different site every time you need to count words, check a loan payment or shrink a photo, you can find the right tool here in seconds. The collection is organized into six categories so you can browse by task.
Text tools help writers, students and marketers work with words. Count words and characters, change text case, compare two versions of a document, remove duplicate lines, generate placeholder text or turn a headline into a clean URL slug. Converters and calculators cover everyday math: convert units, calculate age, work out BMI, find percentages, estimate a loan EMI, measure the difference between two dates, spell out numbers as words and split a restaurant bill.
Developer tools save time when you are coding. Format and validate JSON, encode or decode Base64 and URLs, minify HTML, CSS and JavaScript, test regular expressions, convert HEX, RGB and HSL colors and create SHA hashes. Generators create strong passwords, QR codes, random numbers, dice rolls, coin flips and UUIDs. Image tools compress pictures, convert between JPG, PNG and WebP and turn an image into a Base64 string. For productivity, there is a Pomodoro timer with a stopwatch and a simple to-do list with notes.
Every tool page includes a short guide explaining how the tool works, how to use it step by step, helpful tips and answers to common questions, so you understand the result as well as get it. Because the tools run locally in your browser, they are quick and your content stays private. Choose a category above, use the search box to find a specific tool, or visit our Articles section for practical guides on passwords, images and focus. Learn more about the project on the About page.
