Accurate Conversion Tools

Our conversion tools handle units, colors, images, timestamps, and currencies. Unit conversions follow the International System of Units (SI). Color conversions use mathematically precise algorithms for HEX, RGB, HSL, and HSV. The currency converter fetches live rates from the European Central Bank via Frankfurter API.

Image tools (compressor, HEIC converter, image-to-PDF) process everything client-side using Canvas API and WebAssembly — your photos are never uploaded to any server, ensuring complete privacy.
