About
Standard browser compression often accidentally increases file size, especially when re-saving highly optimized assets. This Smart Compressor solves that problem by analyzing the input and the output. If the compressed version is larger than the original, the tool automatically discards the changes and keeps the original file (Lossless fallback). It also features a Queue System, allowing you to review selected files before processing. Ideally suited for developers, it converts heavy PNGs to modern WebP format by default, often reducing size by 70% to 90% without visible quality loss.
Formulas
The tool uses a Safety Check Algorithm to prevent file bloating:
Visual Comparison alignment uses strict coordinate synchronization:
Reference Data
| Input Format | Recommended Output | Typical Reduction | Notes |
|---|---|---|---|
| PNG (Transparent) | WebP | 60% − 90% | Maintains transparency, drastic size drop. |
| PNG (Opaque) | JPEG | 70% − 95% | Loses transparency, best for screenshots/photos. |
| JPEG (Camera) | JPEG (Low Q) | 30% − 60% | Removes sensor noise and invisible high-freq data. |
| Already Optimized | Keep Original | 0% | Prevents re-compression artifacts and size bloating. |
