Why optimize

Images are your largest payload.

Unoptimized images hurt LCP and bandwidth. Optimizing locally gives you control before you deploy.

What optimizer does

More than compression

Compress

Quality 40–95, engines balanced/fast/maximum. Preview per file.

Resize

Max W×H, downscale only. Ship 1920×1080, not 3840×2160.

Convert

Keep original or output WebP/AVIF — smaller at same quality.

For web

Ship next-gen formats

WebP for compatibility, AVIF for maximum density. Convert the batch where it helps.
