Compression Tips & Formats
- Quality Mode: 70–80% quality offers significant file-size reduction with virtually zero noticeable loss for web photos.
- Target File Size Mode: Automatically searches the optimal quality and dimension scale to fit your requested KB/MB budget.
- WebP Format: Modern browsers achieve 25–35% smaller file sizes than traditional JPEG at equivalent visual fidelity.
- PNG Files: Standard canvas PNG encoding is lossless; for smaller file size, consider WebP or dimension scaling.
100% Privacy & Local Processing
- All image decoding, resizing, and compression runs locally in your browser using native Canvas APIs.
- Your photographs and documents never leave your computer or mobile device and are never sent to external servers.
- Works reliably offline and with VS Code Live Server or static hosting.
- Temporary browser memory is safely released immediately when an image is replaced or cleared.
