Question 1

How to convert images to WebP with Gulp using gulp-webp?

Accepted Answer

Install gulp-webp via npm, then in your Gulpfile, pipe image sources through the webp() function and output to a destination folder, as shown in the README example. You can pass options like quality for customization.

Question 2

gulp-webp vs imagemin-webp: which one should I use?

Accepted Answer

gulp-webp is a Gulp-specific plugin that wraps imagemin-webp for seamless integration into Gulp pipelines. Use gulp-webp if you're already using Gulp; otherwise, imagemin-webp is a standalone Node.js module for broader use cases.

Question 3

Does gulp-webp support converting images to AVIF format?

Accepted Answer

No, gulp-webp only converts images to the WebP format. For AVIF conversion, you'll need to look for other plugins like gulp-avif or use alternative tools that support AVIF, as this plugin is focused solely on WebP.

Question 4

How to handle CMYK images when using gulp-webp?

Accepted Answer

CMYK images are passed through unchanged because WebP does not support CMYK color spaces, as mentioned in the README. This prevents data loss but means they won't be converted to WebP, so you might need separate processing for CMYK images.

Question 5

What are the common options for configuring compression in gulp-webp?

Accepted Answer

You can pass options from imagemin-webp, such as quality (for lossy compression) or lossless (for lossless mode). For example, webp({quality: 80}) sets the quality to 80%, allowing you to balance file size and image quality based on your needs.

Question 6

Why are some of my images not being converted by gulp-webp?

Accepted Answer

gulp-webp only supports converting PNG, JPEG, and TIFF to WebP; unsupported formats or CMYK images are passed through without conversion. Check your input files and ensure they are in supported formats to avoid unoptimized output.
