What is ShrinkFox?
ShrinkFox by Chovexa is a privacy-first, client-side web utility engineered to compress JPG, PNG, WebP, and PDF documents down to exact target file sizes (such as <50KB, <100KB, or custom thresholds) with zero server uploads.
Whether submitting documents to strict government portals, academic application forms, or optimizing web assets, ShrinkFox runs entirely inside the user's browser memory without transmitting a single byte of data across the network.
**100% client-side privacy guarantee:
- Zero Server Uploads: Files are never sent to external servers or cloud storage buckets.
- In-Memory Processing: Compression executes strictly in local browser memory via HTML5 Canvas, WebAssembly (WASM), and client-side rendering engines.
- Instant Memory Purge: All temporary blobs and buffer pointers are destroyed when you clear your queue or close the browser tab.
- Zero Telemetry / Tracking: No user file metrics, image contents, or document metadata are logged or tracked.
Key features:
- Target File Size Optimization: Uses an adaptive binary search algorithm to hit strict file size limits (e.g., exactly = 50KB or = 100KB) while preserving maximum visual fidelity.
- Multi-Format Image Compression: High-performance quantization and compression for JPG, JPEG, PNG, and WebP files.
- In-Browser PDF Compression: PDF page re-rendering, stream decimation, and canvas rasterization directly in the client.
- Batch Processing & ZIP Download: Compress multiple images and documents simultaneously and package the optimized outputs into a single ZIP archive.
- Mobile & Desktop Responsive: Warm-minimalist UI crafted with Tailwind CSS and accessible typography.
