What is Convert Image Format?
An image converter changes the file type of a picture without changing what it looks like. JPG is best for photographs, PNG keeps sharp graphics and transparency, and WebP gives very small files for websites. Some portals only accept JPG or PNG, and some websites prefer WebP, so converting is a daily task for students, bloggers and designers.
