About ToolHub
ToolHub is a collection of browser-based utilities created and maintained by independent developer Hikmat Zirak. The platform features practical tools such as an Image Compressor, Image Resizer, PDF Merger, and Gregorian-to-Jalali Date Converter. Built around client-side technology, ToolHub processes files locally in the web browser using JavaScript and the Canvas API. Because processing happens entirely on the user's device, the service operates without file uploads, stored data, activity tracking, advertisements, or sign-up requirements.
