Frequently Asked Questions
Everything you need to know about image compression, formats and privacy.
Is CompressX completely free to use?
Yes, 100% free with no hidden charges, watermarks, or account registration requirements. You can compress as many files as you need.
Will compression degrade the visible quality of my images?
Our engine uses psycho-visual algorithms that eliminate redundant color data invisible to the human eye. In 99% of cases, your compressed image is visually identical to the original.
What is the difference between JPG, PNG, and WebP?
JPG is ideal for photography, PNG is perfect for transparent logos and graphics, and WebP is the modern standard offering up to 30% smaller file sizes than JPG with superior quality.
Are my uploaded images safe and private?
Absolutely. Uploaded files are processed strictly for compression and automatically purged from our server storage after a short timeframe. Your files are never stored permanently or shared.
Can I compress multiple images at once?
Yes! In Batch mode, you can drop up to 20 images at once and download all optimized results together in a single ZIP archive.
