About Wivrix

Wivrix is an independent personal project: a collection of free in-browser tools — calculators, converters, and editors. It is not a company, not a registered business, and not a bank, clinic, or tax office. The site exists so everyday tasks — converting units, checking a loan payment, formatting JSON, merging a PDF — can be done quickly without signing up, without watermarks, and without shipping your files to an unknown server.

Why it exists

Most similar sites gate basic utilities behind accounts, file-size upsells, or uploads you cannot audit. Wivrix takes the opposite approach: open a page, do the job, leave. Speed and privacy matter more than collecting profiles.

Private by default

For most tools, processing happens in JavaScript on your device. Your PDF pages, photos, and spreadsheet numbers are not sent to Wivrix for conversion. That is what we mean by private by default — the default path keeps data local. A handful of tools must reach the network (currency rates, WHOIS, proxy browsing). Those pages say so plainly, and the privacy policy lists them.

Privacy model in practice

Wivrix does not require an account to use the tools. Theme, favourites, and recent-tool shortcuts are stored in your browser only — not on a Wivrix profile server. When analytics or ads are turned on, a Google-certified consent tool may ask for a choice in regions that require it; see the privacy policy and cookie policy. Ads, when shown, appear outside tool canvases so they never block a convert or download button. If a tool can work offline after the first load, it is built that way on purpose so spotty connections do not block the job.

What you will find here

Tools are grouped by topic: Everyday, Finance, Health & Fitness, Images & PDF, Text & Writing, Security, and more. Each page includes short instructions, examples, and links to guides where a longer explanation helps.

How the site stays online

Advertising through Google AdSense is intended to support hosting and development. Ads stay out of tool canvases and never replace download or convert buttons. Details on cookies and partners are in the privacy policy.

What Wivrix is not

Calculators and health tools give estimates, not professional advice. See the disclaimer before making financial or medical decisions. Wivrix does not provide customer support by phone or post — email is the channel.
