Compress JPEG, PNG, and WebP images in your browser — no upload to any server. Adjust quality level, see before/after file size comparison, and download the compressed result.

80% is a good default — it reduces file size significantly with minimal visible quality loss. Use 90%+ for print-quality output and 60–70% for web thumbnails.
