Photo Compressor & Converter

Compress & convert photos. HEIC support. Private, offline, no watermark.

Running out of storage? Photos too large for WhatsApp, email, or web uploads? NanoPic compresses, converts, and cleans your photos — entirely on your device, no cloud, no account.

Share directly from any app, open photos from your home screen widget, and full HEIC/HEIF support for iPhone photos.

📦 Compress photos without visible quality loss
Reduce photo file sizes from MB to KB in seconds. Adjust quality with a slider, see the estimated output size before you compress, and let NanoPic's safety net ensure you never end up with a larger file than you started with.

🔄 Convert between JPG, PNG, and WEBP
Switch formats in seconds — whether you need JPEG for email, PNG for transparency, or WEBP for web. Batch convert multiple photos at once.

🛡️ Remove hidden EXIF metadata
Your photos silently carry GPS coordinates, device model, timestamps, and camera details. Privacy Mode strips that data before you share — originals stay untouched on your device.

⚡ Smart presets for every platform
Research-backed presets optimized for real-world targets:

Messaging — WhatsApp, Telegram
Email — Gmail, Outlook
Social — Instagram, Facebook
Web — blogs, uploads
Archive — quality-preserving shrink with no resize

Pick a preset, compress, share. No guesswork.
🖼️ Batch compress up to 20 photos
Select, compress, and save an entire batch at once. The custom gallery picker lets you pick multiple photos quickly without fighting the system picker.

📤 Share sheet integration
NanoPic now appears in your system share sheet. Select photos in any app — Gallery, Files, Chrome — and send them straight to NanoPic to compress or clean before forwarding.

📱 HEIC/HEIF support
iPhone photos work natively. Open HEIC files directly and convert or compress them like any other image.

🏠 Home screen widget
One tap from your home screen to start compressing. No need to open the app first.

📊 Track your total space saved
See before/after file sizes for every batch, and watch your lifetime space-saved counter grow with each compression. Achievement tiers keep it satisfying.

🔒 100% offline and private
No internet connection required. No uploads. No account. Your photos never leave your device.

Perfect for:
Shrinking photos for WhatsApp · converting PNG to JPG or WEBP · removing GPS before sharing · batch compressing for email · preparing images for websites and forms · processing iPhone HEIC photos on Android
