Why this tool?

Why Compress Images?

Unoptimized images are one of the biggest culprits behind slow websites and wasted storage. Image compression reduces file size dramatically while maintaining visual quality. This means faster load times, lower bandwidth costs, and better user experience.

How It Works:

Choose between two compression modes: set a specific quality level (1-100) for consistent results, or target a specific file size and let our tool automatically find the perfect quality balance. Compression happens instantly in your browser using advanced algorithms that preserve visual quality.

Compression Strategies:

  • →Quality Mode: Set a quality level (1-100). Lower quality = smaller file but visible loss.
  • →Target Size Mode: Specify your desired file size and our tool finds the right quality to match it.

How to use this tool?

  1. Upload your image - Drag and drop, click to browse, paste from clipboard, or fetch from URL
  2. Choose compression mode - Quality-based or target file size
  3. Set your parameters - Quality level or target file size
  4. Select format - JPEG, WebP, or AVIF
  5. Click "Compress Image" - Optimized image is generated instantly
  6. Download result - Save your compressed image

132-bit Secure & Private

Your data is secure and automatically deleted. All processing is done in your browser with 132-bit encryption. Data uploaded to our servers is automatically deleted after 1 hour of inactivity.

132-bit data secured with encryption*

We use AES-GCM 128-bit encryption combined with HMAC and cryptographic salt, providing effective ~132-bit entropy for any data. This military-grade encryption ensures your image data remains completely private and secure. All data is automatically deleted from our servers after 1 hour of inactivity.

* Technical note: 128-bit AES-GCM + 32-bit HMAC/salt = ~132-bit effective security entropy

FAQ & troubleshooting

What is the difference between quality and target size mode?

Quality mode lets you set a specific quality level (1-100). Target size mode automatically adjusts quality to achieve your desired file size. Use quality mode for consistent results, target size mode when you need a specific file size limit.

Does compression change image dimensions?

No, compression only reduces file size through encoding optimization. Dimensions remain unchanged. To reduce dimensions, use our Image Resizer tool to further reduce file size.

What is the smallest file size I can achieve?

Minimum file size depends on image complexity and content. Simple solid-color images compress more. Target Size mode will automatically find the optimal quality-to-size ratio for your needs.

Which format compresses the best?

AVIF typically achieves the best compression (smallest files), followed by WebP, then JPEG. However, browser support differs—AVIF is newest with less support, WebP is widely supported, JPEG is universal.

Can I compress multiple images at once?

Currently, you compress one image at a time. Batch compression for multiple files is coming in v2 of the tool.

What happens to my compressed image after I download?

Your compressed image is processed entirely in your browser and never uploaded to servers. After downloading, the temporary data is automatically deleted from our servers after one hour of inactivity.
