How it works
Security & Privacy
Free Online Tools — No Sign-up, No Data Stored
Kaeltripton's tools hub gives you 27+ browser-based utilities for everyday file tasks. Whether you need to convert a PDF to Word, compress an image, or quickly calculate UK VAT — every tool is free, requires no account, and leaves zero trace of your files.
Unlike most online converters, all processing happens inside your browser using WebAssembly. Your files never leave your device, are never uploaded to a server, and are wiped from memory automatically. For sensitive documents — payslips, contracts, bank statements — this matters.
Why browser-based tools are safer
Traditional tools upload your file to a remote server, process it there, then send it back — your file travels the internet twice and may be stored temporarily. Kaeltripton tools process entirely locally. The result goes straight to your download manager. Nothing is transmitted over the network.
UK finance calculators
Alongside file tools, this page includes UK income tax, mortgage repayment and VAT calculators — all updated for 2025/26. These complement Kaeltripton's in-depth savings and ISA guides.
