Encoders & Decoders
Base64, hex, JSON formatting, port reference — the format-conversion utilities you reach for many times a day.
A cluster of small, format-conversion tools that share a common purpose: take a string in one shape and return it in another. Each is one of the most-used tools in the application, but each is small enough that a single page covers them all.
Base64
| Mode | What it does |
|---|---|
| Encode | Plain text or bytes → base64 |
| Decode | Base64 → plain text or bytes |
| Auto-detect | Detects mode from input shape |
| Variants | Standard / URL-safe / no-padding (try-all-variants tab shows what each produces) |
| Binary detection | Entropy + null-byte rate flags binary content |
| Chained pipe | Pipe the decoded output into hex / JSON-format / JWT detect with one click |
The chained pipe is the unsung-hero feature. Often a base64-decoded string is itself something else (JSON, JWT, encoded UTF-16, another base64) — the pipe handles the next step without manually copying the intermediate result.
Hex Converter
| Mode | What it does |
|---|---|
| Hex → text | 48656c6c6f → Hello |
| Text → hex | Hello → 48656c6c6f |
| ASCII preview | Side-by-side ASCII column alongside hex (catches printable substrings inside binary blobs) |
| Endianness swap | Swap byte order — useful for little-endian / big-endian conversions |
| Width formatter | 8 / 16 / 32-byte rows for readability |
| Sibling outputs | Binary, octal, decimal alongside hex |
Particularly useful for inspecting magic-byte sequences, decoded protocol fields, and small binary blobs without firing up a hex editor.
JSON Formatter
| Mode | What it does |
|---|---|
| Pretty | Format with chosen indent |
| Minify | Strip whitespace |
| Validate | Confirm valid JSON; flag the error location if not |
| JSONPath query | Extract a specific field via JSONPath |
| Stats | Key / value count, max depth |
| Flatten to dot-notation | {a: {b: 1}} → {"a.b": 1} |
| Sort keys | Alphabetical / reverse / preserve |
| JWT auto-detect | If a string-valued field looks like a JWT, offer one-click decode |
Port Reference
| Field | What it shows |
|---|---|
| Port | Standard service port |
| Service name | Canonical name (HTTP, HTTPS, SSH, etc.) |
| Description | What the service does |
| Category | Web / Mail / Database / Remote / DNS / etc. |
| Common nmap script | The default Nmap script for the port |
| Curated CVE / exploit notes | Brief notes on common exploits per service (defensive context) |
Bulk-paste mode lets you paste a list of port numbers and get the full reference table back.
CIDR & IP-range tools
These also live as part of the Network & IP discipline — the calculator, range expander, and mask preview. They are linked here for completeness but documented in the Network section.
The encoders are perfect candidates for the command palette (Ctrl+K). Type "base", "hex", "json" and the right tool surfaces immediately. For frequently-used tools, pin them to the top of the sidebar (right-click → Pin) and they stay one click away.
Bulk paste
Every tool in this group supports bulk paste. Lines in, converted lines out, exported as CSV / clipboard / Markdown.
