✨ Features

  • Extreme Compression – Transform 80 MB images down to ~200 KB using intelligent resizing and modern codecs (WebP, JPEG, PNG).
  • 100% Private – No files ever leave your device. Everything is processed locally using the HTML5 Canvas API.
  • Batch Processing – Drag‑and‑drop dozens of files at once, then compress them all with a single click.
  • Instant Preview – See side‑by‑side size comparisons before downloading.
  • ZIP Export – Download all compressed images in one convenient .zip archive.
  • Responsive & Modern UI – Clean, industry‑standard interface that works on desktop and mobile.
  • Customisable Presets – Choose between Maximum, High, Medium, Low or tweak quality, dimensions and format manually.
  • Keyboard Shortcuts – Ctrl+Enter to compress all, Ctrl+D to download ZIP.

🚀 How It Works

  1. Drop or select images – they’re listed as cards with original file size.
  2. Adjust settings – use the built‑in presets (like High for razor‑thin results) or go custom.
  3. Compress All – the tool resizes each image to your max‑dimension limit and re‑encodes it at the chosen quality.
  4. Download – grab individual images or the whole batch as a ZIP.

Because everything runs client‑side, your images are never uploaded to any server. Privacy is absolute.

📦 Usage

Run locally

Simply clone the repository and open index.html in any modern browser – no server required.

git clone https://github.com/TutorialsAndroid/image-squash-pro.git
cd image-squash-pro
open index.html   # or double-click it

Deploy to GitHub Pages

  1. Push the repository to your GitHub account.
  2. Go to Settings → Pages and select the branch (usually main) and root folder.
  3. Your app will be live at https://tutorialsandroid.github.io/image-squash-pro/.

⚙️ Configuration

All compression settings are exposed in the UI. The default High preset uses:

  • Quality: 35%
  • Max dimension: 1920 px
  • Output format: WebP

These values strike a balance between tiny file size and acceptable visual quality. For even smaller files, switch to Maximum (20% quality, 1280 px).
