Key Features
100% Offline & Private
Unlike apps that upload your photos to remote servers, every byte of processing happens locally on your device. No internet connection required, no data collected, your photos stay strictly on your phone.
Up to 90% Size Reduction
Watch multi-megabyte photos shrink into tiny kilobytes in seconds. Instantly see the before and after file sizes and the exact percentage of storage you saved on each image.
Format Converter
Apple’s HEIC format is great but doesn’t work everywhere. Easily convert between HEIC, JPEG, and PNG — in either direction — to make your photos compatible with any platform or service.
Pixel Resizer
Reduce the physical dimensions of your images alongside file size compression. Perfect for social media uploads, email attachments, and web publishing where specific pixel dimensions are required.
In-Depth Settings
Fine-tune compression quality, target output dimensions, and output format to match your exact requirements — whether you need maximum compression or a careful balance of size and quality.
Compression History
A quick history log keeps track of your recently compressed images and shows exactly how much space you saved — so you always know the impact of your storage cleanup efforts.
Batch Compression Bulk
Select up to 30 images at once and compress them all simultaneously with the same settings — the ultimate time-saver for cleaning up your Camera Roll or processing entire photo sessions.
Auto-Save to Photos Bulk
Batch compress entire albums and automatically save every compressed result directly back to your Photos library in one tap — no manual export required for each image.

Frequently Asked Questions
Are my photos uploaded anywhere?
Never. The developer has confirmed that no data is collected. Unlike cloud-based compression tools, every operation runs entirely on your iPhone or iPad. Your photos never leave your device.
Does compressing an image reduce its quality?
The app uses smart JPEG quality reduction to shrink file sizes while keeping the visual quality acceptable for most uses. The before and after file size display lets you see exactly what you’re trading — full control is always in your hands via the quality slider in Settings.
What is the difference between the free plan and Bulk Premium?
The free plan lets you compress, resize, and convert individual images with no daily limit. Bulk Premium ($3.99/month or $19.99/year) unlocks batch mode — select up to 30 images at once and process them all simultaneously — plus Auto-Save for saving batch results directly back to your Photos library.
Why should I convert from HEIC to JPEG?
HEIC is Apple’s space-efficient default format, but it is not universally supported — many websites, Windows PCs, and older software cannot open HEIC files. Converting to JPEG ensures maximum compatibility for sharing, uploading, and printing.
Can I cancel my Bulk Premium subscription?
Yes. Subscriptions are managed through your Apple Account in the App Store and can be cancelled at any time. You retain Bulk Premium access until the end of your current billing period, then revert to the free single-image plan.
