The odds and ends: QR codes, colour tools, file inspection. Every tool lists the inputs it accepts, what it produces, its capacity and what happens to your file before you upload anything.
Generate a high-resolution QR code from text, a URL, contact data or any short payload and download it as PNG.
Read QR codes from uploaded images using OpenCV and export the decoded value as plain text.
Convert Unix seconds or milliseconds to ISO dates and convert ISO date-time strings back to Unix timestamps.
Chain compatible file operations so one upload can be converted, optimized and transformed through several steps without re-uploading between tools.
