## What is TestBox?

Ten tools for the things you build and convert every day in testing and development.
Whatever you type stays on your device. Every generator and converter runs entirely on-device.

■ Ten tools

・QR code / barcode scanner
  Hand the scanned result straight to another tool. The last 20 scans stay on your device.

・QR code generator
  Choose the error correction level (L / M / Q / H) and the size.

・Barcode generator
  CODE128 and JAN / EAN, with the check digit calculated for you.

・Random strings
  Up to 65,535 characters. Pick the character sets, and optionally drop look-alike
  characters such as 0 and O, or 1 and l.

・UUID generator
  v1 / v3 / v4 / v5 / v7. v3 and v5 take a namespace and an input string.

・URL encode / decode
  Both RFC 3986 and form-urlencoded. Failed decodes tell you exactly what went wrong.

・Base64 encode / decode
  Standard, unpadded, URL-safe and MIME variants. File input up to 50 MB.

・Hash generator
  MD5 / SHA-1 / SHA-256 / SHA-384 / SHA-512.

・Time zone converter
  Time zone conversion, UNIX timestamps, Japanese era dates and ISO 8601 on one screen.

・Dummy image generator
  PNG / JPEG / GIF / BMP / TIFF / HEIC / SVG / WebP / AVIF, up to 4096 x 4096 px.
  Set the background colour, one of nine patterns, transparency, a border, and text
  with six typefaces, nine positions and effects.

■ Generate in batches

Random strings, UUIDs, hashes and the encoders all take many items at once.
Copy the whole result, or export it as CSV.

■ Pass a result to the next tool

Scan a QR code and URL-encode it. Hash the number from a barcode.
Results move from tool to tool without a round trip through the clipboard.

■ Nothing leaves your device

Pasting a production token or customer data into a web-based converter is against
the rules at most workplaces. Everything in TestBox runs on-device, so what you type
is never sent over the network.
