Free Online Tools & Calculators

Every FaridiaTech tool on one page, mortgages, taxes, BMI, PDFs and all. Each one runs in your browser, needs no account, and answers while you type.

Last updated: October 30, 2026

Every FaridiaTech tool, organised

This page is the whole FaridiaTech catalogue on one screen: all 154 tools, in all 17 categories, with nothing held back behind an account or a premium tier. It is the page to bookmark if you use the site more than once, because it answers the question every regular eventually asks: what else can this place do? The answer ranges from mortgage maths and tax estimates to PDF converters, photo tools, pet calculators and generators you did not know you needed until the day you did. New tools join the page as they launch, so the catalogue you bookmarked last spring is quietly larger by the time you come back.

The organisation follows the shelves the tools live on. Money comes first, with Mortgage and Housing up front, then Everyday Money and Tax, because those are the questions people arrive with most often. Around them sit Home Improvement, Health, Travel, Math and Education, Family and Pets, Cars, Cooking and the rest, each category grouping tools that share a job rather than a keyword. Every card on this page leads to a tool page with the formula behind it and a worked example you can check before trusting it with real numbers. Guides sit alongside the shelves too, longer reads explaining the decisions behind the numbers in plain language.

If you already know the job, skip the browsing and use the filter box at the top of the page. Start typing what you need, a payment, a conversion, a file type, and the grid narrows to the tools that match, so the full catalogue behaves like a shortlist. It is the fastest route when you half remember a tool you used months ago, or when the task is specific: compress this PDF, resize this photo, split this bill. One or two words usually gets you there. The filter understands plain words as well as tool names, so everyday language for the job usually finds the right shelf without site vocabulary.

A few promises hold across every tool listed here. Each one runs in your browser, which means the PDF and image tools never upload your files and the calculators never send your figures anywhere; what you type stays on your device. Each one is free, with no signup, no credits and no daily cap. And each one shows its working: the formula it uses and a worked example you can recompute yourself, with estimates and projections labelled as exactly what they are. If a tool falls short of that standard, its page is the wrong page, and it gets fixed or it does not stay listed here.
