Choose a topic below. The library separates parsing from formatting, encoding from encryption, identifiers from authentication, syntax validity from schema validity, and checksums from trusted signatures. Those distinctions prevent tools from making claims the underlying format cannot support.
JSON and API data
Start with how JSON text becomes values, then diagnose syntax failures and compare structured API payloads without confusing whitespace with data.
Work with the JSON Parser, JSON Repair, JSON Compare, JSON to CSV, or CSV to JSON tools.
Unix time and Discord timestamps
Timestamp bugs often come from mixing units, zones, presentation syntax, or an approximate encoded time with an authoritative business event.
Convert values with the Unix Timestamp Converter or build markup with the Discord Timestamp Generator.
Calendar dates, ages, and durations
Calendar arithmetic is not the same as subtracting timestamps. Month lengths vary, leap years add February 29, daylight-saving changes can make a local day shorter or longer than 24 hours, and ISO week-years can differ from calendar years near January 1.
Use the Age Calculator, Age on a Specific Date, Date Calculator, Days Between Dates, Business Days Calculator, Time Duration Calculator, Week Number Calculator, or Birthday Countdown. Their date-only calculations use exact Gregorian calendar values rather than timezone-dependent midnight timestamps.
Base64 and binary-to-text encoding
Transform bytes locally with the Base64 Encoder and Base64 Decoder. Encoding changes representation; it does not encrypt or authenticate the data.
Number bases, binary bytes, and ASCII
A binary integer, a fixed-width signed bit pattern, and the UTF-8 bytes for a text character can contain the same zeroes and ones while representing different things. Keep the interpretation explicit before converting.
Convert exact integer values with the Binary Converter or Hex Converter, translate text bytes with the Binary Translator, and inspect all 128 standard entries in the ASCII Table.
International Morse code
Morse code represents supported characters as timed dot-and-dash signals. A text display still needs explicit boundaries between letters and words, because spacing carries meaning that a run of punctuation alone cannot preserve.
Use the Morse Code Translator to encode supported text or decode explicit dot-and-dash tokens locally.
Image compression, resizing, and formats
Image file size depends on pixel dimensions, codec, quality, transparency, animation, and metadata. A smaller byte count can require a format change, a lower quality setting, fewer pixels, or more than one of those choices.
Process supported static images with the Image Compressor, Image Resizer, PNG to JPG Converter, WebP to JPG Converter, or WebP to PNG Converter.
Word counts and Unicode characters
Text length depends on the unit being measured. Locale-aware word boundaries, user-perceived grapheme clusters, Unicode code points, UTF-16 storage units, and UTF-8 bytes answer different questions.
Measure prose with the Word Counter or inspect exact Unicode and encoding units with the Character Counter. The English interface supports Unicode text in any language.
URLs, percent-encoding, and query strings
URL components, complete URIs, and form query fields use related but different escaping rules. Decode only at an intentional boundary and keep ordered duplicate query parameters when they carry meaning.
Work locally with the URL Encoder, URL Decoder, URL Parser, and Query String Parser.
UUIDs and GUIDs
UUID text always has 128 bits, but versions assign those bits to random data, names, clocks, nodes, or application-defined layouts.
Generate and inspect identifiers with the UUID Generator, UUID v4 Generator, UUID v7 Generator, UUID Validator, and UUID Decoder.
JSON Web Tokens
Inspect untrusted token text with the JWT Decoder and examine time claims with the JWT Expiration Checker.
SQL dialects
Choose the matching parser mode in the SQL Formatter, including dedicated MySQL, PostgreSQL, BigQuery, and SQL Server pages.
XML structure and validation
Use the XML Formatter, XML Validator, or XML Viewer while keeping well-formedness separate from schema validity.
YAML parsing and conversion
YAML has version-dependent scalar resolution, graph features that JSON cannot preserve directly, and failure modes beyond indentation alone.
Inspect or transform documents with the YAML Formatter, YAML Validator, YAML Viewer, YAML to JSON, and JSON to YAML.
Hashes and file checksums
Hash results depend on exact bytes. Algorithm choice, UTF-8 encoding, line endings, file integrity, and authenticity are separate decisions.
Calculate locally with the Hash Generator, SHA-256 Generator, MD5 Generator, or File Checksum Tool.
