Web Tools: Text Utilities, Encoders and Generators

These free web tools help developers, writers, marketers and SEO specialists prepare content, inspect data and handle common encoding tasks in a browser. Use the JSON Formatter to make data easier to read, the URL Encoder and Base64 Decoder to work with encoded strings, or the Password Generator and UUID Generator to create new values. The SHA-256 Hash tool and Unix Timestamp converter help with other routine development tasks.For writing and cleanup, try the Character Counter, Case Converter, Duplicate Lines Remover and Lorem Ipsum generator. You can also convert between ASCII, hexadecimal and binary, extract email addresses or URLs, and sort or randomize lists.

Converter Tools 20

JavaScript Eval Decode

Paste JavaScript beginning with eval(function(...)) to see the string returned by its inner function, formatted as readable code. Do not use untrusted scripts: decoding can execute JavaScript in your browser.

Unix Timestamp

Convert a Unix timestamp (epoch time) into a human-readable date and time in local and UTC, or turn any date and time into a Unix timestamp in seconds or milliseconds.

JavaScript Obfuscator (eval)

Paste JavaScript into the code field to generate an eval-based packed version. Copy the resulting code from the Obfuscated Code field.

URL Decoder

Decode a percent-encoded URL or string into readable text. Paste it into the Encoded URL field to see the decoded result.

URL Encoder

Encode text or a URL with JavaScript-style percent encoding. Enter a value in Text or URL to get an encoded string you can copy.

PPI

This calculator works out the pixel density (PPI) of a screen from its resolution and diagonal, and converts between pixels and print size at any DPI. Enter width, height and diagonal to get PPI, dot pitch, physical dimensions and viewing distance.

Binary Calculator

Calculate with binary numbers: addition, subtraction, multiplication, division with remainder, bitwise AND, OR, XOR, NOT, and left/right bit shifts. Enter two binary values and get exact results in binary, decimal, hexadecimal and octal, with step-by-step working.

Color Converter

Enter a CSS color name or code to see its RGB, HEX, HSL, HWB, CMYK, and NCol values, along with a color preview.

Hex Converter

Convert text to hexadecimal values or turn space-separated hex codes back into text. Enter your content and choose To HEX or To Text.

ASCII Converter

Convert text into space-separated character codes or turn decimal codes back into text. Enter your content and choose To ASCII or To Text.

Base64 Decoder

Decode a Base64 string and view the resulting text. Paste encoded content into the Base64 String field to see the decoded output.

MD5 Hash

Enter any text and instantly get its 128-bit MD5 hash as a 32-character hexadecimal string. Useful for checksums, file verification, and data integrity checks.

Morse Converter

Convert text to Morse code or decode Morse code back to text. Enter your content, then choose To Morse or To Text.

SHA-256 Hash

Enter any text and instantly get its SHA-256 hash — a fixed 256-bit (64 hexadecimal character) digest. Useful for checksums, integrity verification, and data fingerprinting.

HTML Entities

Convert plain text into HTML entities (&, <, ©) or decode entities back into readable characters. Paste your string, choose encode or decode, and copy the result.

JavaScript Compress

Paste JavaScript into the field to remove unnecessary characters. Copy the compressed code and compare the displayed before and after sizes.

Chmod

Convert Linux file permissions between a clickable checkbox grid, octal code (e.g. 755) and symbolic notation (e.g. rwxr-xr-x). Get ready-to-use chmod commands, an ls -l preview and security notes for regular files and directories.

Binary Converter

Convert text to space-separated binary values or turn binary groups back into text. Enter your content and choose To Binary or To Text.

JSON Formatter

Paste raw, minified or messy JSON to instantly validate it and pretty-print it with your preferred indentation. The tool also shows the exact line and column of any syntax error.

Base64 Encoder

Enter text to convert it to a Base64 string. The encoder works with ASCII and other single-byte characters; characters such as emoji may cause an encoding error.

Text Tools 18

List Randomizer

Shuffle names, tasks, or other list items into a random order. Enter your items, choose how they are separated, and view the reordered list.

Text Separator

Convert a list from one separator to another. Paste your text, select its current separator, then choose a new line, space, semicolon, hyphen, pipe, or period for the result.

List Alphabetizer

Alphabetize a list of names, items, or other text. Enter one item per line and choose A-Z or Z-A to see the sorted list.

Reverse Letters

Reverse the characters in each word without changing word order. Enter text to see the reversed result; extra spaces and line breaks are replaced with single spaces.

Character Counter

Paste or type text to count characters with spaces and without whitespace. The results include letters, punctuation, symbols, and line breaks.

Emojis Remover

Remove emoji-matched characters from text. Paste your text into Text Input to see the cleaned result, then copy it if needed.

Reverse Words

Reverse the order of words in any text. Enter a sentence or passage to get the same words in the opposite order.

Case Converter

Convert text to UPPERCASE, lowercase, Title Case, or Sentence case. Enter your text, choose a Case Type, and copy the converted result.

Random Letter

Draw one random letter for games like Scattergories or generate a list of up to 1000 random letters from the full alphabet, vowels, or consonants. Choose case, exclude letters, and allow or forbid repeats.

URL Extractor

Extract http:// and https:// links from pasted text. Enter content in Text Input to get matching URL strings, one per line.

Reverse List

Reverse the order of items in a list. Paste items into List and choose whether they are separated by new lines, spaces, semicolons, dashes, pipes, or commas.

Lorem Ipsum

Generate lorem ipsum placeholder text by paragraphs, sentences or words (1–100), with or without the classic "Lorem ipsum dolor sit amet" opening. The output includes live word and character counts.

Duplicate Lines Remover

Remove repeated lines from a list while keeping the first occurrence of each line. Paste your list into Text Input to get a trimmed, deduplicated result.

Password Generator

Create strong, random passwords from 4 to 128 characters using uppercase, lowercase, numbers and symbols. The generator uses cryptographically secure randomness and shows the password's strength and entropy in bits.

Upside Down Text Generator

Enter text to turn it into upside-down-looking Unicode characters. The generator reverses the text, substitutes supported characters, and provides a result you can copy.

UUID Generator

Generate one or up to 100 random version 4 UUIDs instantly in your browser. Choose how many you need, switch between uppercase or lowercase hex, and copy the results with or without hyphens.

Email Extractor

Paste text into Text Input to find email-like addresses. The Email Extractor lists each exact match once, in the order it first appears.

Network Tools 3

Subnet

Find an IPv4 network address, broadcast address, host range, and address count. Enter an IP address and choose a prefix length or subnet mask; you can also split the subnet.

RAID

Enter your RAID level, drive count and drive size to find the usable capacity, raw capacity, array efficiency, fault tolerance and estimated speed of your RAID array. Covers RAID 0, 1, 5, 6, 10, 50, 60 and JBOD.

CIDR

Convert an IPv4 CIDR block such as 10.0.0.0/22 into its address range, netmask and host count, convert a first–last IP range into the minimal set of CIDR blocks, or aggregate a list of blocks into one summarized list.
