Why we built this tool

We noticed most image compressors upload files to servers. Since privacy is our core principle, we built this tool to process everything locally using Canvas API and WebAssembly.

About 画像 投げる: what you should know

Designers, content creators, and web developers optimizing visual assets for the web. Whether you need to process an image for a blog post, a product listing, or a responsive layout, this browser-based tool gives you instant results without installing desktop software.

Key features

  • One-Click Download — When you are happy with the result, download the processed image in one click. No watermarks, no sign-up walls, no forced account creation.
  • Local Processing Only — Your image never leaves your browser. Even photos with location EXIF data are processed on-device, protecting your privacy.
  • Direct File Upload — Drag and drop or select an image from your device. The tool supports common formats and gives you a live preview before any processing happens.

Common use cases

  • Standardizing a Batch of Photos — When photos come from different cameras and phones, make them consistent — same format, same orientation — before adding them to a gallery or document.
  • Optimizing Assets for Web — Process product photos, blog headers, or icons before uploading to your site. Smaller files load faster and improve page speed scores.
