I want to resize and compress images using sharp in node.js
In sharp for jpeg there is separate compression and for webp there is separate and for png there is separate.
WEBP
sharp('a.jpg')
.resize(1000)
.webp({quality: 80})
JPEG
sharp('_4_.jpg')
.resize(1000)
.jpeg({quality: 80})
PNG
sharp('_4_.jpg')
.resize(1000)
.png({compressionLevel: 8})
Basically I want to compress and resize image without checking in which format they.
Is there anything for that in sharp ?

NodeJS – Resize() is an inbuilt function that is used to resize the images to the desired size. We can use resize to set the height and width using a 2-pass bilinear algorithm. It can resize an image into any size as declared by the user. We can take input from the user or resize it into fixed Width*Height size.
sharp is a popular Node. js image processing library that supports various image file formats, such as JPEG, PNG, GIF, WebP, AVIF, SVG and TIFF. In this tutorial, you'll use sharp to read an image and extract its metadata, resize, change an image format, and compress an image.
let binary = Buffer. from(data); //or Buffer. from(data, 'binary') let imgData = new Blob(binary. buffer, { type: 'application/octet-binary' }); let link = URL.
If you want the output format to match the input format, you should look at force option.
sharp(input)
.jpeg({ progressive: true, force: false })
.png({ progressive: true, force: false })
...
GIF output is not supported, so GIF input will become PNG output by default.
