Useful should be simple.
Nepocore brings everyday tools together in one calm, convenient place. Convert a photo, work out a percentage, calculate an IELTS practice score, or tidy up some text — without creating another account.
Built around small, real tasks
Every tool in this collection performs a real operation. Calculators explain their assumptions, image tools produce downloadable files, and text utilities keep your input on your device. There are no paid tiers or locked downloads.
Privacy by design
Processing happens in your browser. We do not run a file-upload server. AI background removal downloads its model when requested, then processes the image locally.
Free and open
The website source is available under AGPL-3.0. Third-party packages keep their own license notices. Download the source code or explore all 227 tools.
Who is behind Nepocore?
Nepocore is Nabin Kunwar’s independent toolkit project. Its purpose is to make common image, document, study and planning tasks easier to complete in a browser. The project is not a bank, healthcare provider, school, government service or Google product.
Tools and field notes
The toolkit includes 227 tools and 35 original practical guides. Guides explain actual settings, worked examples and limitations. They were prepared with AI assistance and linked references; no professional or independent editorial review is claimed. Read the editorial and corrections policy for the method and how to report an issue.
