Encode or decode URLs with percent-encoding. Swaps input/output for quick bidirectional conversion. Code never leaves your device — formatting and validation run locally in your browser.
Convert between plain text and binary in both directions — encode text into its base-2 representation or decode binary strings back to readable text, byte by byte. Files are converted locally in your browser — nothing is uploaded.
Translate text to Morse code and decode Morse back — with timing-accurate playback. Learn SOS (···---···) properly — local processing, free, no signup.
Displaying code or angle brackets inside HTML without the browser parsing them.
Named (&) for readability, numeric (&) for maximum compatibility.
Encoding user input neutralizes injection — a core output-escaping defense.
No — encoding runs locally in your browser, free with no signup.
Random Port Generator
Generate random TCP/UDP port numbers from well-known, registered, or dynamic ranges. Useful for network testing, Docker port mapping, and firewall configuration.
Chmod Calculator
Convert between numeric (755) and symbolic (u=rwx,g=rx,o=rx) chmod permission formats. See detailed breakdown for owner, group, and others.
Docker Run to Compose Converter
Convert docker run commands to docker-compose.yml format. Supports ports, volumes, environment variables, networks, restart policies, and container names.
Email Normalizer
Normalize email addresses by removing dots (Gmail), stripping +tags, and lowercasing. Process multiple emails at once for deduplication and cleaning.
Diff Checker
Compares two input texts side-by-side, highlighting inserted, deleted, and changed lines with distinct background colors. Code never leaves your device — formatting and validation run locally in your browser.
IP Address Lookup
Displays your public IPv4 and IPv6 addresses with geolocation data (city, ISP, ASN, timezone). Network engineers use it to verify VPN connectivity. Uses cloud-based processing.
