About frevo.tools
Last updated: July 26, 2026Who we are
frevo.tools is a free collection of everyday utilities and file converters operated by ROXIUS CONSULTORIA LTDA. (trade name Roxius Software), a Brazilian company. We build practical tools for people who need a quick answer or conversion without installing software or creating an account.
What you can do here
The site covers Brazilian document and payroll helpers (for example CPF/CNPJ, CEP, severance and vacation estimates), hardware checks (dead pixels, keyboard), generators (email signature, PIX QR), image and PDF converters in the browser, cloud conversions that need LibreOffice or Calibre, OCR, and downloaders for public Instagram and TikTok videos. Each tool page includes a short explanation and FAQs so you know what the tool does and what it does not do.
How the tools work
Many tools run entirely in your browser: your numbers and files stay on your device for that work. Some converters and media tools need our servers for a short time (for example DOCX to PDF or resolving a public video link). Cloud jobs and video tunnels expire quickly; we are not a file host and we do not require signup for ordinary use. Details are in the Privacy Policy.
