PNG files can become massive due to their lossless nature. Our PNG compressor intelligently reduces the color palette and strips unnecessary metadata, resulting in massive file size savings (often 70% or more) while remaining virtually identical to the naked eye.

よくある質問 (FAQ)

圧縮 画像?
✓ 70-80% quality = 60-80% smaller file size with zero visible artifacts.
Lossy vs Lossless?
Lossy compression (JPG, WebP) permanently removes some image data to achieve smaller files. Lossless compression (PNG) reorganizes data without any quality loss. For photos, lossy is usually fine; for logos with text, use lossless.
Batch 圧縮?
Currently you compress one image at a time to give you full control over quality preview. The entire process takes under 5 seconds per image.
Dimensions change after 圧縮?
✓ 圧縮 only reduces byte weight; pixel dimensions remain identical.
