Free compression for JPG, PNG, WebP, AVIF, JXL images. Smart quality-size balance with real-time preview
All image processing is done locally in your browser via WebAssembly, ensuring privacy. Smart compression balances quality and size, supports batch processing, before/after comparison, and one-click download. Optimizes image loading and transfer efficiency for SEO, social media, email, and more.
Why compress images?
Large images slow down page loading, consume storage and mobile data. Proper compression boosts site speed, improves SEO rankings, and meets platform upload limits. Makes sharing, marketing, and content management more efficient.
JPG Compression?
Oversized images slow page loading and consume storage and data. Proper compression improves load speeds, boosts SEO, and meets platform upload limits for smoother sharing and usage.
PNG Compression?
PNG files are often large, slowing page loading and consuming storage and data. Proper compression significantly reduces file size while preserving transparency and clarity, improving load speeds and meeting platform upload limits.
WebP Compression?
Some original WebP files are still large, consuming storage and data, slowing page loads, and hitting platform upload limits. Moderate compression reduces file size significantly with no visible quality change, enabling faster uploads and smoother loading.
AVIF Compression?
Native AVIF images have high quality but large file sizes, consuming storage and data, and slowing page and mini-program loading. Moderate compression produces nearly invisible differences while significantly reducing file size for faster opening and smoother uploads.
GIF Compression?
GIF animations are often large by default, significantly increasing load times and consuming data and storage. Compressed GIFs are smaller and load faster, effectively improving performance and user experience on web pages, mini-programs, and apps.
JXL Compression?
JXL already has high compression efficiency, but further optimization can make images even smaller, significantly boosting load speeds for web pages, mini-programs, and apps, saving storage and data while maintaining visually lossless quality.
Privacy & Security?
No registration required. All processing is done locally in your browser via WebAssembly. Images are never uploaded to the cloud, collected, or stored. Your privacy is fully protected.
