Compress images online for free. Reduce file size while maintaining quality. No upload to server — everything runs in your browser.
Upload any JPEG, PNG, or WebP image and adjust the quality slider. Lower quality means smaller file size. The compressor uses your browser's built-in Canvas API — your images never leave your device, ensuring complete privacy.
The before-and-after preview lets you visually compare quality at different compression levels. Most images can be compressed 50-80% without visible quality loss, especially photographs where minor detail reduction is imperceptible.
Page load speed directly impacts user experience and SEO rankings. Google uses Core Web Vitals as a ranking factor, and large uncompressed images are the number one cause of slow pages. A 5 MB hero image that could be 200 KB costs you visitors and search rankings.
Email providers limit attachment sizes (typically 25 MB for Gmail). Social media platforms re-compress uploaded images, often with poor results. Compressing before upload gives you control over quality and ensures your images look their best everywhere.
