Why we built Tolvix
Tolvix is an independent collection of free online utilities for common digital tasks. The goal is straightforward: help people complete small jobs—such as counting words, calculating a percentage, formatting JSON, resizing an image or organising a PDF—without installing a separate desktop application for every task.
What you can do on the site
The tools are organised into seven areas: text tools, calculators, developer and data tools, image tools, PDF tools, everyday or security utilities, and SEO, writing and productivity tools. The homepage directory lists the available tools and links to their individual pages. Tolvix also publishes practical guides that explain common workflows, examples and mistakes to avoid.
How we design and review tools
We aim to make each tool understandable, quick to use and available without an account for basic features. We work to explain accepted inputs, outputs and limitations. Many tools process information in the browser rather than sending it to a Tolvix file-processing server, but some features rely on third-party services or browser libraries. Check the individual tool page and our Privacy Policy before using a feature with sensitive information.
We improve validation and instructions as issues are found. We review outputs and guidance for clarity, but no online utility is guaranteed to be suitable for every situation. Check important calculations and documents before relying on them—especially for financial, health-related, legal, tax or official purposes.
Editorial approach
Our guides are intended to explain practical tasks in plain language, show examples where useful and identify important limitations. They are general educational material, not professional advice. For decisions that depend on current rules or specialist knowledge, consult an authoritative source or qualified professional.
Corrections and suggestions
If a tool behaves unexpectedly, an explanation is unclear or you have an idea for an improvement, please use the Contact page. Include the relevant page URL and a description of the issue. Do not post passwords, private files or sensitive personal information in a public report.
