Best Tips to Reduce Image Size Without Losing Quality
✅ 1. Use JPG instead of PNG
PNG images are heavier. Convert PNG → JPG before compressing.
✅ 2. Resize image dimensions
Reducing resolution from 4000px → 1200px drastically lowers size.
✅ 3. Remove unnecessary background
Plain backgrounds compress better.
✅ 4. Reduce DPI (for documents)
72 DPI is enough for digital uploads.
✅ 5. Use smart compressors (like ToolsOnlineHub)
Ensures high quality even after reducing file size.
