# Image Encoding Tuning for Weight, Loading, and Delivery

Tune PNG bit depth, palette, and transparency, choose progressive or baseline JPEG loading, dial WebP quality modes, and compress TIFF for archives until every image fits its destination.

## Frequently asked questions

### Progressive or baseline JPEG, which one should I ship?

Progressive renders earlier on slow connections and is often slightly smaller, but some older editors and processing pipelines mishandle progressive scans. Ship progressive for web delivery, and convert back to baseline when a downstream tool visibly breaks.

### What is the difference between palette PNG and 8-bit PNG?

Both are the low-weight road for flat art. Palette PNG stores an explicit indexed color table and excels on UI screenshots and icons, while photographic content bands at low depth and belongs in 24-bit RGB instead.

### When does 16-bit PNG actually earn its size?

High-precision grayscale such as scientific, medical, or depth data, and edits that need headroom before final export. Ordinary web delivery gains nothing from it and pays in bytes.

### Which WebP mode should I choose?

Icons and line art belong in lossless or near-lossless so edges stay crisp, photographs tolerate lossy with a quality step far better than PNG-with-photograph ever did, and the alpha choice follows the layout, not habit.
