Tips for Best Results

Format Selection

Choose your output format before optimization. Select from WebP, JPG, JPEG, PNG, or AVIF based on your needs and browser compatibility.

Batch Processing

Process up to 10 images simultaneously for faster workflow.

Privacy

All processing happens in your browser. Your images never leave your device.

File Size Reduction

Achieve 30-90% size reduction depending on format. Cross-format conversions (e.g., JPG to WebP) typically achieve 75-90% reduction, while same-format optimization achieves 30-40% reduction.

Custom Resizing

Enter custom width or height dimensions to scale down your images while optimizing, maintaining perfect aspect ratios automatically.

Forced Format Conversion

If target output format differs from input format, the converter forces format conversion even if no size reduction is possible.
