Top calculators
A short starting set for the most common computing & data science calculators workflows.
JSON Formatter Tool – Pretty Print, Minify, and Validate JSON Online
Format JSON in your browser by pretty-printing, minifying, and checking syntax before you copy it. No server upload is needed.
IBAN Validator & Generator (MOD 97 / ISO 13616)
Validate or generate an IBAN (International Bank Account Number) using the official ISO 13616 MOD 97-10 checksum algorithm. Runs fully in your browser.
Browser Image Resizer and Base64 Export
Resize an image to exact pixel dimensions in your browser, preserve its aspect ratio when needed, preview the result, and copy its PNG Base64 data URI.
Deepfake Detection Failure Risk Calculator | Frame-Level Evasion Risk
Estimate how likely a deepfake video is to evade automated screening in this frame-level model using detector accuracy, compression quality, attacker skill, frame rate, and duration.
Gibbs Free Energy Calculator | ΔG from Enthalpy, Entropy & Temperature
Calculate Gibbs free-energy change (ΔG) from reaction enthalpy, entropy, and temperature, then animate the model reaction extent and download its energy trajectory as CSV.
