Format, validate, convert, generate, inspect, test, and document development data with 1,102 focused utilities powered by Zactra Technologies.
Clear inputs, one obvious primary action, copy and download controls, and readable errors.
See every tool →JSON Formatter & Beautifier helps you format and normalize JSON with readable indentation, syntax-aware spacing, validation feedback, and copy-ready output directly in the browser where supported.
JWT Decoder & Token Inspector helps you decode JWT tokens into readable output with strict input checks, Unicode handling, and clear errors for invalid sequences directly in the browser where supported.
SQL Formatter & Beautifier helps you format and normalize SQL with readable indentation, syntax-aware spacing, validation feedback, and copy-ready output directly in the browser where supported.
UUID v4 & v7 Generator helps you generate UUIDs from labeled options and deterministic templates, with copy, download, reset, and production-review guidance directly in the browser where supported.
Image Compressor & Optimizer helps you compress images with visible quality or size controls, before-and-after measurements, safe limits, and downloadable output directly in the browser where supported.
Base64 Encoder & Decoder helps you encode Base64 data into the selected transport or storage representation while preserving Unicode and exposing malformed-input errors directly in the browser where supported.
URL Encoder & Decoder helps you encode URLs into the selected transport or storage representation while preserving Unicode and exposing malformed-input errors directly in the browser where supported.
Unix Timestamp & Epoch Converter helps you convert Unix timestamps and dates between the documented source and target formats, keeping important values, ordering, and normalization choices visible directly in the browser where supported.
Text Diff Checker & Compare Tool helps you validate text against its documented syntax, structure, required fields, and common edge cases, with precise issues instead of a generic pass/fail directly in the browser where supported.
Hash Generator for MD5 & SHA helps you generate MD5 and SHA hashes from labeled options and deterministic templates, with copy, download, reset, and production-review guidance directly in the browser where supported.
YAML to JSON & JSON to YAML Converter helps you convert YAML and JSON between the documented source and target formats, keeping important values, ordering, and normalization choices visible directly in the browser where supported.
XML Formatter & Beautifier helps you format and normalize XML with readable indentation, syntax-aware spacing, validation feedback, and copy-ready output directly in the browser where supported.
The master catalog covers 37 categories. Only functional utilities are published as tool pages.
See build status →Most transformations use browser APIs and browser memory. Protected live-data operations, account actions, deliberate sharing, search, and contact forms are separate and clearly labeled.
Text, code, tokens, files, and generated values stay in browser memory whenever the web platform supports the operation.
Primary actions are easy to find; advanced options are shown only when they help.
Decoding is not verification, formatting is not execution, and generated output still needs target-system testing.
