Compression of images before upload to Squarespace 7.1

Recommended Posts

Hello!

I know it is "best practice" to always upload compressed images to web reduce load-time etc.

But I wonder if Squarespace anyway will compress the uploaded files, so there will be no need to do it beforehand?

I'm adding a link to a page where I have made an image gallery (slide-show), built in Squarespace 7.1, Fluid Engine:

https://www.hoyden.no/universitetsgata-7

(The images in this slideshow is not compressed before uploading)

Squarespace recommend that you save the images at a high "quality" setting (95+ in most image tools) and then upload them without additional compression. 

To quote what I said in another thread, when you upload an image to Squarespace, the platform does some resizing which necessitates re-encoding and re-compressing. If you compress an image before uploading it, the mandatory re-compressing will usually result in a larger file size because the algorithm won't know the difference between "actual image content" and "artifacts of the previous compression run".

I hope this helps.

Checked out your gallery, and it looks fantastic! About the image compression, it's a common concern. Squarespace does apply some compression, but it's a good idea to compress before uploading for optimal performance. JPEG Optimizer is a solid tool for that. Personally, I think a little compress image beforehand helps maintain a good balance between quality and load time. It's like finding that sweet spot! Your slideshow is super smooth though, kudos! If you ever want to share tips or experiences, I'm all ears.
