About CamTtuk Tool

CamTtuk Tool is short for “Campus Ttukttak Tool” (캠퍼스 뚝딱툴 in Korean): campus tasks, done in a snap, with nothing to install.

CamTtuk Tool is a free website that gathers the small tools you keep needing for school and everyday work. Counting characters in a personal statement, turning iPhone photos into JPG, bundling a stack of photos into one PDF: simple jobs you would otherwise search for every single time, now all in one place.

What we stand by

• Files are processed only on your device. Every conversion and calculation happens inside your browser. Your photos, documents and typed text are never sent to a server.
• No sign-up, no install. Open the page and start right away.
• No file limits, no watermarks. Use it as much as you like.
• Works on your phone too. Every tool works the same on desktop and mobile.

How the site is run

The site is funded by the ads shown on its pages, which is what lets us keep every tool free. You can read how advertising cookies are used in our Privacy Policy.

Korean-only tools

The Korean version of this site also offers a Korean tone converter (switching between formal and casual speech) and an AI-writing self-check tool. Both work with Korean text only, so you will find them on the Korean home page.
