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. ■ TestBox Pro ・No ads ・Batches of up to 500 at a time (free: 15 per run after a rewarded ad, twice a day) ・No ad before saving a dummy image ■ About the subscription ・TestBox Pro, monthly or yearly ・250 JPY per month / 1,800 JPY per year (prices vary by region) ・Payment is charged to your Apple ID account at confirmation of purchase. ・The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. ・The renewal is charged within 24 hours before the end of the current period. ・You can manage or cancel the subscription in your App Store account settings. ・Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ・Privacy Policy: https://twilight-gambler-281.notion.site/Privacy-Policy-3d58126a5b98807993aaf9b417257639
