Top calculators
A short starting set for the most common computing & data science calculators workflows.
JSON Formatter Tool ā Online JSON Beautifier, Pretty Printer & Vali...
Online JSON formatter and validator. Pretty-print, minify, and copy JSON instantly in your browser with no data sent to a server.
IBAN Validator & Generator (MOD 97) | International Bank Account Number Tool
Validate or generate an IBAN (International Bank Account Number) using the official ISO 13616 MOD 97-10 checksum algorithm. Runs fully in your browser.
Blockchain Node Storage Growth Calculator (Full Node Disk Space Estimator)
Estimate blockchain node disk space growth over time from average block size, block interval, pruning percentage, and replication copies. Includes a year-by-year storage table, formulas, assumptions, and planning guidance.
Deepfake Detection Failure Risk Calculator
Estimate how likely a deepfake video is to bypass automated screening using detector accuracy, compression quality, attacker skill, frame rate, and duration.
Gibbs Free Energy Reaction Simulator
Explore how enthalpy, entropy, and temperature shape reaction spontaneity. An HTML5 canvas animates progress while energy bars reveal ĪH, TĪS, and ĪG contributions.
Mouse DPI Sensitivity Converter - Convert Sensitivity While Keeping eDPI Consistent
Convert mouse sensitivity when changing DPI so your effective DPI stays consistent across profiles, mice, and many games.
Dataset Re-identification Risk Calculator
Estimate the probability that individuals in an anonymized dataset could be re-identified using k-anonymity, dataset coverage, external data availability and attribute sensitivity.
Image Resizer
Resize pictures directly in your browser by drawing them to an HTML canvas.
