Data & Conversion

The Data & Conversion universe brings together 49 free tools for transforming, checking and understanding data. You can encode text, convert units, generate QR codes and work with numbers. Tools such as Text and binary, Caesar Cipher or Length Converter cover common tasks. Everything runs in your browser, with no sign-up.

To choose, start with the kind of data: text and characters, numbers and calculations, measurements, or QR codes. The subcategories Character Encoding, Classic Ciphers, Strings & Alphabets, Number Formats, Integer Arithmetic, Fractions & Stats, Unit Conversion, QR Contact & Messaging, QR Places & Events, QR Payments & Crypto, QR Web & Network and Barcodes & Batches organise the tools. Pick the closest subcategory, then compare tools by input and output format.

How to use

Start by naming the transformation you need: text to bytes, character to code, number to format or measurement to another unit. This keeps you inside Data & Conversion and avoids the wrong tool.
For text, begin with Text and binary, Unicode Code Points or Character codes, then move to Base32 encoder, Punycode or Quoted-printable when that format is required.
For numbers, pick Number formatting, Numbers in words or Roman numerals according to the display you want, then check the value before copying it.
For QR codes, choose by the action after scanning: contact, message, place, payment, network or campaign, then test the content on a phone before sharing.

Frequently asked questions

Do these tools keep my data?

The tools state that processing happens in your browser. You can use them for quick tests, one-off conversions or checks without creating an account. Always review the result before relying on it for something important.

Where should I start if I do not know the subcategories?

First decide whether your need involves text, numbers, units or a QR code. The matching subcategory lists the available tools. For a simple exchange, start with the tool whose title exactly describes the input and output you expect.

How do I choose between a conversion tool and a simple cipher tool?

If you only need a different representation, use a conversion tool such as Text and binary or Number formatting. If you want text to be less readable at a glance, use ROT13 Encoder, Caesar Cipher or Morse code. These ciphers are not serious protection.

What should I check before sharing a result from this universe?

Review the input, the selected unit or format, and compare the output with what you expect. For a QR code, scan it with the target device. For a number or measurement, check decimals and separators.
