Base64

Turn images into Base64 text and back again, without uploading anything.

Text to Base64 Encode text as Base64 in UTF-8 or a legacy Windows code page.
Base64 to Text Decode Base64 back to text, switching character sets until it reads right.

Base64 to Image Paste Base64 text or a data URI, see the image and download it as a file.
File to Base64 Encode any file, with the type read from its bytes rather than its name.
Base64 to File Decode Base64 into a file and find out what it turned out to be.
Base64URL and Base64 The same bytes in both alphabets, with the padding accounted for.
Gzip and Base64 Compress text and encode it, or take a compressed blob back to text.

Text

Reshape, count and tidy up text without leaving the page.

Case Converter Convert text into nine cases at once — upper, lower, title, camel, snake and more — with correct Turkish i handling.
Line Tools Sort, de-duplicate, trim, number and reorder a list of lines in one pass — with Turkish-correct sorting.
Broken Character Repair Turn "é", "ü" and "—" back into é, ü and — : text that was saved as UTF-8 and read as something else.
Text file encoding converter Rewrites a text file from one character encoding into another — the old Windows-1254 file that needs to be UTF-8, and back. Characters, not media.
Text Counter Characters, words, sentences, reading time and byte size, counted the way a reader would count them.
Find and Replace Replace text across a whole block, literally or with a regular expression.
Text Compare Put two blocks of text side by side and see which lines were added and which were removed.
Slug and ASCII Folding Turn a title into a URL-safe slug, or just strip the accents and keep the writing.
Placeholder Text Generate filler paragraphs, sentences or words in Latin or Turkish.

Lists

Compare two lists, count what repeats, add up a column, and turn the result into something you can paste.

Compare two lists Union, intersection, subtract: what is only in A, what is in both, what is only in B.
Duplicates and counts Every line with how many times it appears, or only the ones that repeat.
Numeric list Sum, mean, median and spread for a pasted column of numbers, sorted as numbers rather than as text.
Columns and lists Join two lists side by side, or take one column out of a table pasted from a spreadsheet.
List to code A JSON array, an SQL IN list or a comma-separated line — with a sample, a slice or fixed-size chunks.

Hash

SHA digests of text and of files, worked out on your own machine.

Text Hash SHA-1, SHA-256, SHA-384 and SHA-512 of a piece of text, with the character encoding as a visible choice.
File Checksum Drop a file to get its SHA digests, and paste a published checksum to see straight away whether it matches.
HMAC A keyed hash: proves a message came from someone holding the same secret.

Encoding

Escape and unescape text for URLs, HTML, JSON and source code.

URL Encode / Decode Percent-encode text for a URL and read it back, with the choice between a whole address and a single value.
HTML Encode / Decode Turn text into safe HTML and entities back into text, without ever building markup.
JSON String Escape Turn text into a JSON string literal and read an escaped literal back.
Unicode Escape Write non-ASCII characters as \uXXXX, U+XXXX or numeric references, and read all of those back.
Hex and Text Text to hex bytes and back, in whichever charset the bytes were written in.
Binary and Text The same conversion in ones and zeroes, eight bits to the byte.
Punycode and IDN türkiye.com and xn--trkiye-3ya.com are the same address written two ways.
Quoted-Printable The mail encoding that turns günaydın into g=C3=BCnayd=C4=B1n, both ways.

Data

Read, tidy and convert JSON, CSV, XML and query strings.

JSON Formatter Indent, minify and check JSON, with the line and column of whatever stopped it.
JSON ↔ CSV Turn a list of records into a spreadsheet and back, quoting and all.
CSV Viewer Paste a CSV and read it as a table, with the delimiter worked out for you.
JSON Compare Compare two JSON documents by structure, so key order never counts as a change.
YAML and JSON Convert between YAML and JSON in either direction, with anything the reader does not fully implement refused by name rather than guessed at.
XML Formatter Indent and validate XML using the browser's own parser.
Query String ↔ JSON Read a query string as JSON and build one back from an object.

Time and Numbers

Timestamps, time zones, cron schedules, number bases and byte sizes.

Unix Timestamp Read an epoch number as a date, or a date as an epoch number, in seconds or milliseconds.
Time Zone Converter See one moment as the clock shows it in as many zones as you like.
Date Difference How long between two dates, as calendar units and as a plain total.
Cron Explainer Read a cron expression back field by field, and see when it will actually run.
Number Base Converter Binary, octal, decimal, hexadecimal and any base up to 36, at any size.
Byte Size Converter The same size in every unit, decimal and binary side by side.
Roman Numerals Numbers to Roman numerals and back, with the malformed ones rejected.

Colour

Convert between colour formats, check contrast, build scales and gradients.

Colour Converter One colour in every notation — HEX, RGB, HSL and OKLCH, with alpha carried through.
Contrast Checker The contrast ratio between two colours and whether it passes WCAG, seen on a live sample.
Shade Scale A full light-to-dark scale from one colour, stepped so it looks even rather than measured even.
Gradient Builder Build a linear, radial or conic gradient and copy the CSS.

Image

Resize, convert, crop and read what a picture carries — decoded and written back in the browser.

Resize and convert Change the size, the format and the quality of one image or a batch of them, and see what each change costs.
Crop Drag a region, or type the exact pixels, and export just that part.
Favicon set One picture into every icon size a browser asks for, plus favicon.ico and the markup to reference them.
Placeholder image A plain image at the size you need, labelled with that size, for a layout that is not finished yet.
Image metadata The camera, the settings, the date and the coordinates a photo carries — and a copy with all of it removed.

Web Development

Regex, tokens, status codes, media types and the markup a page needs.

Regex Tester Try a pattern against text and see every match, group and capture as you type.
JWT Decoder Read a token's header and payload, check when it expires, verify an HMAC signature.
HTTP Status Codes Every status code with what it actually means, searchable.
MIME Types The media type for a file extension, and the extensions for a type.
Screen and viewport What size this page is actually being shown at, on this device, right now — and how many real pixels that is.
What your browser reveals Your address, your agent, your browser and everything else a page learns about you without asking.
User-Agent Parser Break a user-agent string into browser, engine, operating system and device.
Meta Tag Generator Open Graph and Twitter card tags, with a preview of the card they produce.
srcset Generator Build a responsive image tag with width or density descriptors.
.env and JSON Turn a .env file into JSON and back, quoting and escaping included.

Türkiye

Checks for the numbers used in Türkiye — identity, tax, IBAN and plate codes — none of which leave your browser.

T.C. Kimlik No Check the checksum of a Turkish identity number, without sending it anywhere.
Tax Number (VKN) Check the checksum of a ten-digit Turkish tax number.
IBAN Validate and format an IBAN from any country, with the Turkish layout broken out.
Plate Codes Plate code to province and back, all 81, searchable.

Generators

Identifiers, passwords and key material, drawn from the browser's cryptographic randomness.

UUID Version 4 or version 7, one at a time or a thousand at once.
Password Passwords with the character classes you need, and the entropy stated in bits.
Random Key Random bytes as hex or Base64, for a secret a program will read.
QR Code Text or a link as a QR code, drawn in your browser and downloadable.

Draw and Pick

Draws that can be checked afterwards: a seed you can publish, and the same result every time it is re-run.

Raffle Draw Paste the entrants, draw winners and reserves, and keep the seed so anyone can re-run the same draw.
Spinner Wheel The same seeded draw as a wheel: the winner is decided first and the wheel is steered to it.
Elimination Draw A list into a single-elimination bracket, round by round, with the byes drawn and shown.
Group Draw A list dealt into groups, optionally from pots so the strong entrants are spread.
Running Order A pasted list shuffled into a numbered turn order, reproducible from its seed.
Random Numbers Numbers from a range you choose, with or without repeats, reproducible from a seed.
Dice and Coin Roll dice in 3d6+2 notation or flip coins, with the seed shown for every throw.
Gift Draw Secret Santa pairing: everyone gives to somebody, nobody draws themselves, and couples can be kept apart.
