About This Tool

Description

This is a secure, client-side image compression tool powered entirely by your browser's capabilities (HTML5 Canvas). It provides "advanced" control over the three primary vectors of image size reduction: **Lossy Compression Quality** (percentage), **Resizing** (pixel dimensions), and now **Target File Size** (iteratively adjusting quality until a target KB is met). You can see the file size savings in real-time, allowing you to find the perfect balance between image quality and file size for web optimization. All processing is done locally, ensuring privacy.

How to Use

• Upload Image: Select a JPG or PNG file. Initial file information will be displayed.
• Select Mode: Choose between **Quality Slider** (manual control) and **Target File Size** (automatic control).
• Quality Mode: Use the **Compression Quality** slider and optionally specify **Max Width/Height** for maximum control.
• Target Mode: Enter the desired **Target Size (KB)**. The tool will automatically find the lowest quality setting needed to reach that size while trying to preserve as much quality as possible.
• Review Results: Check the **Compressed Image Preview** and the size comparison statistics. The compression automatically runs with every change. The **Applied Quality** field confirms the final quality setting used.
• Download: Click the **Download Compressed Image** button to save the optimized file.

Useful For

• Web Developers & SEO: Meeting specific file size budget limits (e.g., below 100 KB) for optimal page speed.
• Bloggers & Content Creators: Reducing image file sizes for articles and social media without sacrificing too much visual quality.
• Email Users: Compressing large photos before attaching them to emails to avoid size limits.
