MAZANOKE is a simple, privacy-focused image optimizer that runs entirely in your browser. It compresses and converts images locally on your device, can work offline, and is designed as a safer alternative to online “free” image tools.
Key Features
- In-browser image optimization with adjustable quality
- Target file size compression option
- Resize controls with max width/height limits
- Clipboard paste support for quick imports
- Format conversion to and between JPG, PNG, WebP, and ICO
- Import support for HEIC, AVIF, TIFF, GIF, and SVG (with configurable output defaults)
- EXIF metadata removal to reduce privacy leaks (e.g., location/date)
- Installable as a web app (PWA-style) for offline use
Use Cases
- Compress photos before sending via email or chat without uploading to third parties
- Convert mixed image formats (e.g., HEIC/AVIF) into more compatible formats
- Remove EXIF metadata before publishing images online
MAZANOKE is well-suited for individuals, families, and small teams who want fast, private image optimization with a lightweight, shareable self-hosted setup.
