Toolerax is a browser-based toolbox of 169 free online utilities covering PDF, image, text, developer, SEO, security, converter and calculator jobs, each usable without an account or install.
What is Toolerax?
Toolerax is a free online tools website whose 169 utilities run inside the browser rather than as installed desktop software. It accepts uploads such as PDF, .docx, .xlsx, .pptx, HEIC, TIFF, EPS, PSD and AVIF files, plus pasted text, JSON, CSS and HTML, and returns processed documents, converted files, images, formatted code or computed numbers. The tools are grouped into eight collections — Text Tools, Developer Tools, SEO Tools, Security Tools, Converters, Calculators, Image Tools and PDF Tools. The site describes the collection as fast, private and free for everyone.
