画像圧縮ツール
プライバシーを守るため、サーバーにアップロードせずに画像を圧縮します。
概要
ブラウザ内で安全に画像サイズを縮小します。
Common Use Cases
- Reduce image size before uploading assets into a CMS, blog, or landing page so pages load faster.
- Generate lighter JPEG previews for tickets, email attachments, or content-review workflows.
- Compress images locally in the browser before deciding whether they should enter your final publishing pipeline.
What This Tool Does Not Replace
This tool is useful for fast local compression, but it is not a full image pipeline. Production delivery still benefits from responsive images, correct format selection, caching rules, and build-time optimization.
