TatraTools is a free online toolkit for converting and optimizing images without signup. I built it after getting tired of simple file converters overloaded with ads, pop-ups, confusing limits and bloated interfaces. Convert HEIC, JPG, PNG, WebP, AVIF, SVG, PDF and ICO files directly in the browser. Useful for HEIC to JPG, WebP/AVIF images, PDF to image, SVG to PNG and favicon generation.
