Dagochim (다고침, roughly "fix it all" in Korean) is a collection of free tools and plain-language guides for everyday computer problems. Merge a PDF, convert a photo, shrink a video, or follow a step-by-step guide to recover deleted files or reinstall Windows, with no sign-up and nothing to install.
Our principles
- Free to use. Every tool and guide is free. No account required.
- Your files stay on your device. Our tools process photos, PDFs and videos locally in your browser. They aren't uploaded to our servers.
- No scare tactics. We don't invent urgency or push paid "fix-it" software. We start with official, built-in solutions and say clearly when something is uncertain.
- Ad-supported. The site is paid for by ads shown on the page. Ads are kept separate from the content, and advertisers don't influence what we write.
About our guides
Guides are based on official documentation from companies like Microsoft, and we re-check menu names and steps when we write or update them. Software changes often, though, so what you see on screen may differ slightly. Always back up important data before making system changes.
Product and company names mentioned in our guides belong to their respective owners. Dagochim isn't affiliated with them.
