WEBP is a modern image format developed for the web. It supports transparency like PNG, but produces files that are typically 25 to 35 percent smaller. Switching PNG assets to WEBP is one of the most effective ways to improve page load speed.
The conversion uses the browser Canvas API at 90% quality, which gives you files that look the same as the original while taking up less space. Transparency is preserved. The output file keeps the same filename with a .webp extension.
Your file never leaves your device. This makes it safe to convert private screenshots, design work, or internal assets.
