About Nceptia
Nceptia is a collection of free calculators and browser utilities for students, writers, developers, sellers, and anyone who needs a quick answer without installing software or creating an account.
Why browser-local tools?
Many online converters upload your files or text to remote servers. Nceptia tools are built to run in your tab with JavaScript, WebAssembly, or Canvas APIs where possible. That keeps drafts, salary figures, product photos, SQL practice databases, and JWT tokens on your device instead of transiting through our infrastructure.
What we offer
- Finance — currency conversion, mortgage amortization, salary estimates, tips, and compound growth illustrations.
- Writing & text — word counts, text cleanup, Markdown preview, diffs, and case conversion.
- Developers — JSON formatting, regex testing, JWT decoding, Base64, UUIDs, CSV viewing, and an SQLite playground.
- Images & files — batch resizing for marketplaces, OCR, duplicate detection, PDF merge, and checksum verification.
- Scheduling & health — time zones, meeting overlap, countdowns, BMI estimates, and fitness helpers.
Accuracy and disclaimers
Finance and health tools show illustrative results, not professional advice. Tax models are simplified. Mortgage schedules exclude escrow and insurance. Always confirm important numbers with qualified professionals or your institution.
