Free browser-based tools for image conversion, image-to-PDF documents, text cleanup, percentages, unit conversion, QR codes, passwords and reading time estimates.
SWS Universe is not intended to be an endless directory of disconnected widgets. This version focuses on practical tools for specific tasks: image conversion, image-to-PDF documents, text cleanup, percentage math, unit conversion, QR code generation, password generation and reading-time estimates.
Each visible tool includes usage notes, limits and decision criteria. The goal is to get a quick result while also understanding when a format, formula or setting is the right choice.
Each card summarizes the use case, decision criteria and access link for the tool.
