iDownsize 3.1

This application has been recognized as a top 10 paid Photo & Video app in the iPad category in Germany. It offers a straightforward solution for managing photo storage without intrusive advertisements or additional charges.

Key Features:

• Enables compression of selected photos or entire albums, facilitating easier storage and sharing.
• Allows users to carry their complete photo collections conveniently, promoting mobility and accessibility.
• Supports downsizing photos from external cameras or existing photo libraries for optimized sharing and uploading.

Operational Workflow:

1. Select individual photos or entire albums for processing.
2. Choose the preferred level of compression.
3. Preview the image quality with a sample check prior to finalizing the compression.
4. Specify a name for the new album where compressed images will be stored.
5. Initiate the downsizing process; compressed files will be saved within the specified album.
6. Optionally, permit automatic deletion of original files, moving them to the 'Recently Deleted' folder in the Photos app. Users should subsequently empty this folder to free storage space.

Important Notes:

• The app saves all compressed images in the device's camera roll. The created album contains only links to these files, which are stored in the camera roll itself, conforming to Apple’s restrictions.

Image Quality Considerations:

IPhone: The device's camera captures images at resolutions significantly higher than the display size, allowing substantial compression without perceptible quality loss. For example, compressing an iPhone 5S photo by 80% can reclaim over 2.5 GB of storage across approximately 1,000 images, with no noticeable display degradation.

Camera Resolutions and Display Sizes:

• iPhone 6 Plus: 3264x2448 pixels (3.3 MB); display: 1920x1080
• iPhone 6, 5, 5S: 3264x2448 pixels (3.3 MB); display: 1136x640
• iPhone 4S: 3264x2448 pixels (3.3 MB); display: 960x640
• iPhone 4: 2569x1908 pixels (2.0 MB); display: 960x640

Ipad: Larger screens enable more effective photo collection and viewing. Different models support resolutions such as:

• Ipad Pro: 2732x2048 pixels
• Ipad Air 2, 4th, 3rd Gen: 2048x1536 pixels
• Ipad 2 and earlier: 1024x768 pixels

Using an iPad Air, photos can be reduced to resolutions up to 2048x1536 pixels with minimal visual impact on image quality.

Digitally sourced images from external cameras benefit significantly from compression. High-resolution photos up to 15 MB per image can be reduced below 1 MB without noticeable loss of display quality—for instance, compressing a 5 MB image (5184x3460 pixels) down to approximately 1024x700 pixels results in more than four gigabytes of storage savings across a thousand images.

If there are concerns about image quality loss during compression, users can preview a sample image before proceeding. Our tests indicate that reducing resolution to around 1024x768 pixels on devices such as the iPad 2 does not compromise visual clarity, even on HD-ready televisions (which typically display at this resolution). For viewing on Full HD screens, downsizing up to approximately 1920x1080 pixels maintains excellent fidelity.
