Image Smaller uses advanced compression algorithms to reduce file sizes while maintaining visual quality. The compression happens entirely in your browser - no images are uploaded to our servers, ensuring complete privacy.

We support multiple compression methods:

• Lossy compression: For JPG, WebP, AVIF formats (adjustable quality)
• Lossless compression: For PNG images (optimizes file structure)
• Smart compression: Automatically chooses the best method based on your settings

Image Smaller supports the following image formats:

• JPG/JPEG: Most common format for photos
• PNG: For images with transparency
• WebP: Modern format with excellent compression
• AVIF: Next-generation format with superior quality
• JPEG XL (JXL): Advanced format with lossless compression

You can also convert between these formats during compression.

There are no strict file size limits since processing happens in your browser. However, performance depends on:

• Your device's memory (RAM)
• Browser capabilities
• Image dimensions (megapixels)

For best results:

• Single images: Up to 50MP (recommended)
• Batch processing: Up to 20 images at once
• Total batch size: Up to 500MB

The quality setting (0-100) controls the balance between file size and image quality:

• 90-100: Nearly lossless, small size reduction
• 80-89: Good quality, noticeable size reduction
• 70-79: Balanced, recommended for web
• 60-69: Smaller files, slight quality loss
• Below 60: Maximum compression, visible artifacts

Tip: Start with 80 and adjust based on your needs. The preview shows the quality difference.

Yes, absolutely! Image Smaller processes all images locally in your web browser:
