K4Converter in One Paragraph
K4Converter (k4converter.com) is a free set of online file tools created by Prakhar Singh, a software engineer from India, and launched in 2026. Every tool runs inside the browser, so files are processed on the visitor's own device and are never uploaded to a server. It covers PDF tools (merge, sign, PDF to JPG, images to PDF), image converters (HEIC, PNG, JPG, WebP, SVG, JFIF, ICO), an image resizer that can hit an exact file size such as 20 KB, and everyday calculators. There's no signup, no watermark and no file limit.
