Byte Drop — Remove a Byte Range
Delete a range of bytes from text, hex, or Base64 by start offset and length, and view the remainder in any format. Free, private, runs in your browser.
Byte Take — Extract a Byte Range
Extract a byte range from text, hex, or Base64 by start offset and length, output as text, hex, or Base64 — free byte slice tool, runs in your browser.
Mojibake Fixer / Charset Transcoder
Fix mojibake and re-decode legacy charsets (Windows-1252, Latin-1, Shift_JIS, GBK, Big5, KOI8-R) into clean UTF-8 — free, private, in your browser.
Data URI Decoder
Decode a data: URI into its MIME type, charset and payload — text decoded inline, binaries with detected type and hex preview, all in your browser.
Data URI Encoder
Turn text into a self-contained data: URI with a chosen MIME type and Base64 or percent encoding. No sign-up, runs offline in your browser.
Find & Decode Base64
Scan any text for embedded Base64 blobs and decode them — showing decoded text, or a file-type + hex preview for binaries. Runs in your browser, nothing uploaded.
Hex Encoder / Decoder
Encode text to hex and decode hex back to text in your browser. Delimiters, uppercase, and 0x prefixes; tolerant decoding accepts any format. Free and private.

LZ-String Compress / Decompress
Compress and decompress text with LZ-String in your browser — Base64, URL-safe, or UTF-16 output, byte-compatible with the lz-string JS library. Free, private.
Morse Code Translator
Translate text to International Morse code and decode Morse back to text in your browser — A-Z, 0-9, punctuation, custom separators. Free and private.
Multi Encoder
Encode or decode text across Base64, hex, binary, URL-encoding, ROT13, and Morse — one tool, both directions. Runs in your browser, nothing uploaded, free.
String Escaper
Escape (or unescape) any string for JSON, JavaScript, HTML, URL, shell, SQL, or regex. Spec-aware escaping that runs in your browser; nothing is uploaded.
Text to Unicode
List each character's Unicode code point (U+XXXX), name, \u escape sequence and UTF-8 bytes for any text.
Unicode to Text
Decode Unicode escape sequences back into readable text. Auto-detects \uXXXX, \u{X}, \xXX, \U00XXXXXX, U+XXXX and HTML &#nn; / &#xnn; in one pass.
URL Encoder / Decoder
Percent-encode or decode text and URLs in your browser — component, whole-URL, or form mode, batch per-line, and recursive decode. Free, private, no sign-up.
Compress a Video to a Target File Size
Set an MB budget and it computes the H.264 bitrate from your clip's length to fit under it — for Discord, email or WhatsApp. Runs in your browser, nothing uploaded.
