為什麼用這個工具
03Shrink image file size with WebP, JPEG, or PNG output, set a quality target, and resize by max width — all client-side.
Image Optimizer compresses and reformats JPEG, PNG, and WebP files locally using the browser Canvas.
Use it before uploading photos, posting marketing assets, or shipping web images where payload size matters.

常見問題
03
Is my image uploaded to a server?
No. The image is read into the current tab and compressed with Canvas. Nothing leaves your browser.
Which format should I pick?
WebP gives the best compression for photos and UI assets. Use JPEG for compatibility and PNG when you need lossless output.
Does quality affect PNG output?
No. PNG is lossless, so the quality slider is ignored. Reduce dimensions with max width instead.
