Large image files slow down websites, consume data, and hurt user experience. Optimized images reduce bounce rates and improve SEO rankings. All Quick Tool provides free image optimization without any backend uploads - everything runs in your browser.
1. Image Compression Basics
Compression reduces file size while maintaining visual quality. Our compression tool uses modern algorithms to achieve 60-80% size reduction on average.
Best for: Photographs, PNG files, photos with gradients
Expected size reduction: 50-70% depending on original quality
2. Image Resizing for Different Platforms
Different platforms need different dimensions:
- Instagram: 1080x1080px (square), 1200x628px (landscape)
- LinkedIn: 1200x628px
- Twitter: 1200x675px
- Web thumbnails: 300x300px or 400x400px
3. Image Format Conversion
Choose the right format for your use case:
