About Omnipus

Omnipus is a catalog of 280 free browser tools — converters, generators, calculators, and a few downloaders — built so everyday file jobs do not require an account or a mystery upload farm.

Operated by Ruben Rocha (Portugal / EU). There is no separate company registration page and no street address published here; contact is by email at hello@omnipus.co.

Most PDF, image, audio, and text tools run entirely in your browser with open libraries (pdf-lib, PDF.js, FFmpeg.wasm, Tesseract.js, Mammoth, and others). Your files are not stored on Omnipus servers for those tools. Each page shows a privacy badge so you can see the mode before you start.

A smaller set of tools needs the network on purpose: downloaders fetch a public URL you paste (and do not keep a media archive), the currency converter reads public ECB reference rates, and the RuneScape signature can look up a player’s public hiscores. Those cases are labeled in the tool header. Heavy tools like background removal, OCR, and video download their engine or model the first time — that is a download to your browser, not an upload of your file.

Alongside everyday converters we keep niche utilities — Discord timestamps, resistor codes, chmod, CIDR, Secret Santa — so those searches land on a page that works.

Labeled Adsterra ads fund hosting and development — no popunders or redirects. Slots sit away from primary actions to avoid accidental ad clicks.
