FAQ
No. This tool only reduces file size by adjusting quality/compression settings. Dimensions remain unchanged.
Lossy compression (JPEG) does reduce visual quality slightly. PNG compression is lossless - No quality loss. WebP supports both lossless and lossy modes.
Typical JPEGs at quality 75 are 40–70% smaller than the original. Results vary depending on image content.
