FAQ

What's the difference between lossy and lossless compression?

Lossy compression reduces file size by removing some image data, which may slightly reduce quality. Lossless compression reduces file size without any quality loss. Our tool uses smart lossy compression that maintains visual quality while achieving significant size reduction.

What quality setting should I use?

For web images, 80-90% quality is ideal. It provides excellent visual quality with good file size reduction. For photos where quality is critical, use 90-95%. For thumbnails or background images, 70-80% works well.

Which format compresses best?

AVIF offers the best compression, followed by WebP, then JPG. However, AVIF and WebP have limited browser support. JPG is universally supported and still provides excellent compression.

Can I compress PNG files?

Yes! PNG files can be compressed by reducing color depth or converting to more efficient formats like WebP or AVIF. For photos, converting PNG to JPG often provides better compression.

Will compression affect print quality?

For print, use minimal compression (95%+ quality). Web compression settings (80-90%) are optimized for screen viewing and may show artifacts when printed at large sizes.
