Truly free, truly private: tools that run in your browser
austudio gathers the small tools you reach for every day: WhatsApp order links, email and call links, digital business cards that save to contacts, image compression and resizing, PDF merge and split, character counter, unit converter, age and day calculators, wheel and giveaway pickers, color picking from images.
The difference: every tool runs entirely in your browser. The photo, PDF or text you bring never leaves your device — it is not uploaded, stored or processed. That's why there is no account, no watermark and no limit.
The tools are built by Alperen Uçum as a showcase of his web design work, and the collection grows slowly. Want a new tool? Message me on Instagram.
