HEIC Compressor
Shrink HEIC files by up to 80%. Optimized local processing, no uploads.
Shrink HEIC files by 20-40% (up to 80% on large photos) without visible quality loss — free, private, and in-browser. Batch-compress up to 500 files while keeping EXIF and portrait data. No uploads.
Shrink & Optimize HEIC File Size Without Quality Loss
Modern iPhones take stunning 48MP photos, but high-resolution HEIC files can easily reach 5MB to 10MB each. When you need to send photos by email, upload galleries, or save phone storage, HEIC Compressor allows you to reduce file size by up to 80% without losing visual clarity.
📉 Smart Compression
Intelligent lossy compression removes redundant color data while keeping sharpness pixel-perfect.
📁 Batch Compression
Compress up to 500 HEIC photos simultaneously using multi-threaded Web Workers on your PC or phone.
🔒 Private & Offline
Your photos stay on your device throughout the compression process. No cloud uploads, ever.
Why Compress HEIC Photos?
While HEIC uses the efficient HEVC codec (H.265), camera sensors store massive amounts of high-dynamic-range detail that isn't always necessary for daily sharing or web publishing. Compressing your HEIC images gives you several advantages:
- Email Attachment Compliance: Keep your photo bundles under the strict 25MB email size limit.
- Accelerate Web Loading: Optimize product photos and portfolio galleries for better Google Core Web Vitals and lower bounce rates.
- Free Up iPhone & Cloud Storage: Reclaim gigabytes of space on iCloud or local hard drives without deleting precious memories.
- Keep Portrait & EXIF Metadata: Preserve camera settings, creation dates, and GPS coordinates while shrinking file dimensions.
How Our Browser-Based HEIC Compressor Works
Cloud compression services require uploading your sensitive personal photos to external servers. HEIC.dev processes selected image files locally in your browser tab. Using WebAssembly (WASM), your CPU compresses the image data locally in browser memory. This makes compression faster (no upload latency) without transmitting photo binaries to a conversion backend.
