Convert images between PNG, JPEG, and WebP with a quality slider and optional resizing, all inside your browser. WebP typically produces files 25–35% smaller than JPEG at the same visual quality; PNG remains the right choice for transparency and sharp graphics.
Re-encoding happens on your device with the browser's native image engine — fast, private, and no queue. Convert screenshots for documentation, photos for websites, or graphics for upload requirements that demand a specific format.
WebP for web photos (smallest, universally supported in modern browsers); JPEG for maximum compatibility with older software; PNG for anything needing transparency or crisp edges — logos, screenshots, diagrams.
WebP is lossy like JPEG at quality settings below 100 — at 80+ quality, differences are practically invisible while files shrink dramatically. Choose PNG if you need lossless output.
Yes — set target dimensions along with the format to resize and convert in one pass.
