You can reduce photo size using our online compressor — it compresses JPG and PNG images by 25-70% without visible quality loss. Just upload a file, select the compression level, and download the result. All processing happens in your browser, files are never uploaded to a server.
Image compression is essential for faster website loading, saving disk space, and reducing bandwidth usage. Even at maximum compression, the quality remains acceptable for web use. For photos, low or medium level is recommended; for graphics and icons, go with high compression.
Image optimization directly affects SEO and user experience: Google considers page load speed as a ranking factor. Compressed photos load faster on mobile devices and slow internet connections, improving Core Web Vitals and user retention.
Which compression level to choose?
| Level | Compression | Quality | Best For |
|---|---|---|---|
| Low | 10-25% | Maximum | Photos, quality critical |
| Medium | 30-50% | Good | General purpose |
| High | 50-70% | Average | Web, fast loading |
