About Oson Studio

Oson Studio started in 2026 from one simple idea: learning, and everyday digital chores too, should be free and free of fuss for everyone. Today it gathers courses on artificial intelligence, Excel, accounting and web development, an IQ test, typing practice, and dozens of tools for working with PDFs, images and documents, all in one place.

Why this site exists

Most useful services come in a foreign language, behind a paywall, or with a «sign up first» barrier. I wanted to do these same things in Uzbek, for free, and with no strings attached. You open the site and get straight to work. No subscription, no ads, no account to create.

What you'll find here

There are two big directions. One is courses you pick and learn from scratch; the other is tools that get a single job done fast.

• Courses, interactive and with a certificate: Prompt Engineering, AI agents, AI images and video, Pro Excel, Accounting (NSBU), digital safety, Loop Engineering, HTML and CSS, intro to programming.
• IQ test, questions on logic, math, words and equations, with an analysis of your result at the end.
• Typing, lessons that teach you to type fast on the keyboard, a speed test and a few typing games.
• Programming, CSS Battle, Flexbox and Grid games, and an online code editor for many languages.
• Documents, merge and split PDFs, convert between PDF and JPG, rotate, compress, Latin and Cyrillic.
• Other tools, password generator, QR code, screen recording, background removal, online whiteboard, temporary email.

Your files stay with you

Most of the tools never touch a server at all; everything runs directly in your browser. That means your images, videos and PDFs don't go anywhere, they are processed only on your own device. There's a nice side effect too: the work finishes almost at once, because you aren't waiting for a file to travel out to the internet and back.

Only a handful of tools, such as AI image quality or temporary email, rely on an outside service. I've written that out plainly, without hiding it, in the Privacy Policy.

Is it really free?

Yes, free from start to finish. No payment, subscription or registration is asked for, and you won't see any ads on the pages. If the site has been handy and you'd like to help me keep it going, you can support it through Tirikchilik or Rahmat. But that is entirely up to you.

Who is behind it

I, Eldor Ergashov, started this project as an independent developer, and I run it myself. There is no big team behind it, so every course and every tool is built by hand, one at a time, and improved little by little.
