📋 How to Use This Tool

1. Drag & drop your image or click the upload area to select any file (JPG, PNG, WebP, HEIC, ARW, SVG, PSD, etc.)
2. Adjust the Quality slider (lower = smaller file size, higher = better visual quality)
3. Toggle Lossless Mode if you want perfect pixel-for-pixel quality
4. Click Convert to HEIC — everything happens instantly in your browser
5. Check the live size comparison and compression savings
6. Click Download .heic to save your converted file

*Note: HEIC encoding works best in Safari (iOS & macOS). Chrome, Edge & Firefox may show “encoding not supported” because they lack native HEIC export.
