Batch Compress Technical Support

Compressed files are saved to the "Compressed" album in your iOS Photos library by default. You can view them in the Photos app. Original files remain unchanged and are never deleted from your device.

Open the app > Go to "Settings" > Tap "Restore Purchases" > Sign in with the Apple ID used for purchase > Wait for verification to complete.

Note: Please ensure you are signed in with the same Apple ID used for the original purchase, and your device is connected to the internet.

Light Compression: Reduces file size by 30-40% with virtually no visible quality difference.

Deep Compression: Reduces file size by 50-60%, suitable for scenarios where quality requirements are not critical.

Extreme Compression: Reduces file size by 70-80%, suitable for scenarios where quality requirements are not critical.

Custom Mode (Premium): Manually adjust compression quality parameters to find the optimal balance between file size and quality.

Input: HEIC, JPEG, PNG, TIFF, GIF, MOV, MP4, M4V, etc.

Output: JPEG, HEIC, PNG (photos), MP4 (H.264/HEVC encoded videos).

Speed depends on file size, device performance, compression mode, and device temperature. We recommend keeping your device charged during batch compression and avoiding use in extreme temperature environments.
