Frequently Asked Questions
How much can images be compressed?
Compression ratios vary by image content and format. JPEG images can often be reduced 50-80% with minimal visible quality loss. WebP typically achieves even better compression than JPEG at the same quality level.
Is any quality lost during compression?
JPEG and WebP use lossy compression, so some quality is lost (controlled by the quality slider). PNG compression is lossless — file size reduction comes from optimizing the encoding, not removing data.
Which output format should I choose?
WebP offers the best compression-to-quality ratio and is supported by all modern browsers. JPEG is universally compatible. PNG is best when you need lossless quality or transparency.
