What this WebP converter does

Format-focused entry into the same luminosity pipeline.

WebP is a common photo format. This landing targets that intent while using the same private Rec. 709 conversion as the main tool.

When to use the WebP converter

Use it when your source file is a WebP.

Phone and camera exports

Many devices still default to WebP for everyday shots.
Quick social mono

Convert and download PNG for feeds that prefer non-proprietary formats.
Batch of files

Use the batch converter when you have many images at once.

Tips for WebP mono

Keep the plate clean unless style is the goal.

Leave grain and vignette at zero for documentation plates. Switch to vintage or noir when atmosphere matters.
