Hi everyone! I’m currently building my ecommerce website using Wix Studio, and I’ve run into a bit of a challenge that I’d love some guidance on.
I’ve already uploaded around 450 product listings, and each product has 5 to 9 high-resolution images (uploaded as JPGs). Unfortunately, I just realized that each image is around 5MB to 9.3MB 
Now I’m worried this might drastically affect my website’s loading speed, especially on mobile. I want to know:
Is there any way to compress or replace these images in bulk inside Wix without deleting every product manually?
Does Wix offer any internal tools or media manager features to optimize uploaded images after publishing?
Or should I download everything, compress it externally (like with WebP or tools like XnConvert), and re-upload them again product by product?
Would really appreciate help or suggestions from anyone who has faced a similar issue 
It’s not currently possible - although Wix does some compression, and conversion when serving media to live sites (e.g. to AVIF), but it’s likely not as far as you’ll get with external tools.
It’s recommended to upload images as AVIF, which is a newer type of image file, better than JPEG and approximately 50% smaller than WebP.

Thank you so much for the clarification and the helpful insight on how Wix handles image compression! I really appreciate the tip about using AVIF. I’ll definitely explore that format for better optimization. This helps a lot as I work on keeping my site sleek and fast. Appreciate your support!
Hii @Sioral_Jewellery , Large images can certainly impact loading speeds, especially on mobile, so it’s great that you’re focusing on optimizing them. Image compression can be done by the online tools available in the market. However, first not going for the tool rather you can try using the WebP format for the images so convert all your images.
WebP uses both lossless and lossy compression techniques, providing high-quality images at a smaller file size. Lossy WebP compression offers similar quality to JPEG but at a smaller size, while lossless WebP compression offers superior quality to PNG.
Doing both these above steps can enhance the performance and can solve website images loading delays.
Alternatively, if your website speed still is not performing well I would recommend Website Speedy- best optimization tool that automates the process of image compression, Font optimization and Handling HTTP Request, etc. This tool can generate the results for you at ease and in less time. It comes with a 14 day money back offer.
