Performance Tips

Group similar images - Process photos and graphics separately with appropriate settings
Use WebP format for modern web applications - it offers superior compression
Enable resizing if images are larger than needed for their intended use
Start with 20-30 images to test settings before processing large batches
Monitor browser memory when processing very large batches (50+ images)
Use balanced compression for the best trade-off between speed and file size

Frequently Asked Questions

How many images can I process at once?

You can process up to 20 images simultaneously. For larger collections, we recommend processing in batches of 10-15 images for optimal performance.

Will the original image quality be preserved?

Our compression maintains visual quality while reducing file size. At 80-90% quality settings, differences are virtually indistinguishable while achieving 60-80% size reduction.

Can I compress different image formats together?

Yes! You can mix JPG, PNG, and WebP files in the same batch. The compressor will handle each format appropriately based on your settings.

How long does batch processing take?

Processing time depends on image sizes and quantity. Typically, 10 images (2-5MB each) take 10-30 seconds. The progress indicator shows real-time status.

Do you keep my images after processing?

No. All image processing happens directly in your browser. Your images are never uploaded to our servers, ensuring complete privacy and security.
