About tinyimg
What Is This?
tinyimg is a free, privacy-first batch image compression tool that runs entirely in your browser. We convert and compress JPEG, PNG, WebP, AVIF and JXL images, and accept MotionPhoto input — without ever uploading them to any server.
Why tinyimg?
Most online image compressors upload your images to their servers, process them, and send them back. This means:
- Your images travel over the internet (slow and insecure)
- The server has a copy of your images (privacy concern)
- You're limited by server capacity and upload speed
tinyimg does everything on your device using WebAssembly — the same battle-tested compression libraries compiled to run in your browser at near-native speed.
Features
- Batch processing — compress up to 50 images at once (20 on phones)
- Multi-format output — convert to JPEG, PNG, WebP, AVIF, and JXL simultaneously
- Zero-server architecture — everything happens in your browser
- Multi-language — available in 8 languages
- ZIP download — batch download all results at once
- Privacy safe — images never leave your device
- MotionPhoto input — only the still image is compressed; the embedded video is copied through unchanged, byte for byte, and the output stays a MotionPhoto
