Batch compression tips
For website images, WebP often gives smaller files. JPG is useful for broad compatibility. Keep PNG for graphics that need transparency, but remember that PNG quality settings may not reduce size as much as JPG or WebP.
常見問題
Does batch compression upload images?
No. Your images stay in your browser and compression runs locally.
Which format is smallest?
WebP is often smallest for photos, while JPG is a compatible fallback.
Can I limit image width?
Yes. Set max width to downscale large photos during compression.
