About 1001Ferramentas

1001Ferramentas is a free hub of online tools — calculators, generators, converters and validators, plus utilities for text, dates, SEO and security — organized into 11 categories and served in Portuguese (our primary language) and English. Our mission is simple: make everyday digital tasks fast, free and available without sign-up.

What we offer, and who it's for

Whether you're a student, a developer, a marketer or just getting something done, there's probably a tool here for it. A few examples by category:

  • Calculators — BMI, compound interest, net salary, loan simulations.
  • Converters — units, number bases, colors, timestamps.
  • Generators — strong passwords, QR codes, test documents.
  • Validators — CPF, CNPJ, credit cards, Pix keys.
  • Text — word and character counts, case conversion, slugify.
  • Dates — difference between dates, business days, exact age.
  • SEO — meta tags, robots.txt, sitemap and canonical helpers.
  • Security — hashes, password strength, two-factor codes.
  • Plus games, dev utilities and general utilities.

How the tools work

For most tools, the computation runs entirely in your browser using JavaScript — so the data you type never leaves your device or reaches our servers. A small number of tools query public third-party APIs (such as postal-code lookup, currency rates or a leaked-password check); those requests go directly to the providers. We explain this in detail in our Privacy Policy.

Who runs the site

1001Ferramentas is built and maintained by a small, independent team based in Brazil. The catalog is large, and we are steadily reviewing it: for the tools we feature, we test the calculation and write the explanation by hand, and we welcome corrections from readers. If something looks wrong, telling us helps everyone.

How the site is funded

The site is free to use and supported by advertising, including Google AdSense. Ads are what let us keep the tools open and free, without paywalls. Advertising involves cookies — see the Privacy Policy for the full disclosure and your opt-out options.
