Utilities & Converters
Developer utilities and format converters that run entirely in your browser. Your JSON, files, and images are processed locally — nothing is uploaded to any server.
JSON to TypeScript
Paste JSON, get typed interfaces — nested objects and arrays handled automatically.
ENCODERBase64 Encoder & Decoder
UTF-8 safe text encoding with a URL-safe option for tokens and query strings.
CONVERTERJSON to YAML
Two-way conversion for Kubernetes, Docker Compose, and CI configs.
CONVERTERJSON to CSV
Flatten nested JSON into Excel-ready CSV with dot-notation columns.
GENERATORFavicon Generator
One image in — favicon.ico, every PNG size, and the HTML snippet out.
SEOURL Redirect Checker
Trace full 301/302 redirect chains and catch equity-leaking hops.
CONVERTERBase64 to Image
Decode Base64 strings to viewable images — and images back to data URIs.
SECURITYFile Hash Checker
Verify downloads with SHA-256, SHA-512, SHA-1, and MD5 — hashed locally.
Why these run in your browser
Every tool in this category processes your data on your own device. That's not just a privacy nicety — the things people paste into converters (API responses, configs, internal file hashes) routinely contain hostnames, tokens, and real user data. Client-side processing means there is no server log anywhere containing what you converted. The only exception is the redirect checker, which necessarily makes one server-side request to follow another site's redirects — and it stores nothing.
