From "deleting videos" to "slimming videos". VidDiet is an app that dramatically reduces file sizes while minimizing quality loss, maximizing your phone's free storage space. Is your phone storage full of videos, preventing you from taking new photos or updating your OS? "I don't want to delete any of my precious memories..." VidDiet solves this exact problem. 【Core Values & Features】 ◆ High-Quality Compression Minimizes visible quality loss, shrinking the file size while keeping your videos looking beautiful. ◆ Full Metadata Preservation (Highly Practical) Unlike other compression tools, VidDiet preserves metadata such as video creation date/time, location (GPS), and camera settings. ◆ Custom Target Size Calculation Specify a target size (e.g., "under 10MB" or "easy to share via email/SNS"), and VidDiet automatically calculates the optimal compression rate. ◆ 100% On-Device Processing (Secure & Private) All compression happens entirely on your device. Since videos are never sent to external servers, your private videos remain secure, and the app works lightning-fast offline. 【Key Features】 • Simple video compression in just a few taps • Custom compression targeting a specific file size • Side-by-side preview to compare quality and size before/after • Securely delete the original video after compression to free up space instantly 【Recommended For Anyone Who:】 • Constantly sees the "Storage Almost Full" warning • Has too many videos of family, kids, or pets, and refuses to delete them • Wants to keep travel or event videos at high quality • Wants to save on cloud storage fees (iCloud, Google Drive, etc.) • Has lost location or timestamp metadata after compressing videos elsewhere 【About Diet Pass (Premium Plan)】 VidDiet offers an optional "Diet Pass" to make your experience even better. (*Basic compression features are available for free.) • Batch Compression (process multiple videos at once) • Faster processing speeds • 100% Ad-Free experience *About Auto-Renewable Subscriptions: You can disable auto-renewal by managing your subscription at least 24 hours before the end of the current period. *Manage & Cancel: Go to App Store -> Account Icon (top right of Today tab) -> Subscriptions. 【Privacy Policy & Terms】 Your video data is never sent to external servers.

If you have any feedback or feature requests, please let me know! I hope VidDiet helps keep your storage clean and supports your digital life.
