Free, no-signup utilities for documents, media, SEO, education & everyday tasks.
Zokilos is a collection of small, focused, free utilities — PDF and document builders, image and audio/video converters, SEO and site-analysis tools, classroom tools, and a long tail of everyday utilities like unit converters, generators, and text formatters. Each one does one job and does it without asking you to sign up first.
Most tools run entirely in your browser: type into the word counter, drag a crop box, convert a color — nothing leaves your machine. A smaller set of tools need server-side processing (compressing a PDF, running OCR, removing an image background) — those files are processed for the single request and then discarded. We don't keep a library of what anyone has uploaded.
There's nothing to create an account for. If a tool is listed, it's usable right now, for free. Some tools call out to a third-party service to do their job (live exchange rates, search data) — those are documented on the privacy policy page.
