Shrink videos, images, PDFs, and archives to the exact size you need. 100% offline, private, and precise. Now with batch compression and text-preserving PDFs!
Local File Diet is a professional, local-first utility designed to solve one specific problem: shrinking files that are too large for email, WhatsApp, forms, or public portals, without compromising quality more than necessary.
Unlike generic tools, Local File Diet gives you precise control over the final file size and processes everything strictly on your device. No cloud uploads, no accounts, and no subscriptions.
**KEY FEATURES:**
• **Precise Video Compression:** Target an exact file size, and the app will hit it (usually within 4% in a single pass) using a smart resolution ladder and bitrate calculation.
• **Smart PDF Compression:** Reduce PDF sizes while keeping your text fully selectable. Image-dominant pages are optimized, while text layers are preserved perfectly.
• **Batch Processing:** Select multiple files at once and compress them all in a single batch flow. Save them individually or pack them instantly into a ZIP archive.
• **Image Optimization:** Strip metadata, preserve alpha channels (transparency), and downsample smartly to hit your target sizes.
• **Universal File Support:** Works with videos, images, PDFs, and ZIP archives.
• **Share Extension:** Compress files directly from any app using the iOS Share Sheet.
**PRIVACY FIRST:**
• **100% Local Processing:** Your files never leave your device.
• **No Analytics or Tracking:** What you do on your device stays on your device.
• **No Subscriptions:** Pay once, use forever.
