Wordpress LScache Plugin: Image group increasing site size
Last Updated on: Wed, 15 Apr 2026 00:00:02 The Lightspeed cache plugin creates different dimensions of image groups for a single image. That is significantly increased my site size (single jpeg size 200kb ? optimized webp image group size 3Mb). FTP Screenshot Is there any way to use the single image without creating different resolutions, or reducing the image group size. Removing these different image versions will reduce the loading speed? It will be a great help if someone gives me a solution. This topic was modified 2 weeks ago by samwp1. The Lightspeed cache plugin creates different dimensions of image groups for a single image. That is significantly increased my site size (single jpeg size 200kb ? optimized webp image group size 3Mb). What makes you think that an image group increases in size? Hi, these groups are NOT created by LSCWP it just scans/reads/gathers what you have on your site Best regards, What makes you think that an image group increases in size? The uploading jpeg size is 200kb. When it is optimized to a webp image the group size 3Mb. it looks like you have some misunderstanding and mis-conception how wordpress image works lets say when you upload an image , 200 KB , res 1000 x 1000 at the moment you upload it , your wp will create some resized thumbnails , for how many variety , it depends on your system and plugin/theme , but lets imagine there are 4 of them , small 100 x 100 , middle 300 x 300 , large 800 x 800 and custom size for 500 x 500 so you upload 1 image, but WP will create 4 more of them , so you will have total 5 images like something.jpg -> 200 KB something-100x100.jpg -> 20 KB something-300x300.jpg -> 70KB something-500x500.jpg -> 100KB something-800x800.jpg --> 160 KB so you uploaded a 200 KB image , but WP will take 200 + 20 + 70 + 100 + 160 = 550 KB disk space , this is default WP doing , not related/caused by LSCWP and if you do image optimization , as backup and webp will be created , it will be something like something.jpg -> 150 KB optimized original something.jpg.webp -> 120 KB webp version something.bk.jpg -> 200 KB original backup something-100x100.jpg -> 15 KB optimized original something-100x100.jpg.webp -> 10KB webp version something-100x100.bk.jpg -> 20KB backup something-300x300.jpg -> 50KB optimized original something-300x300.jpg.webp -> 40KB webp version something-300x300.bk.jpg -> 70KB backup something-500x500.jpg -> 80KB optimized original something-500x500.jpb.webp -> 60KB webo version something-500x500.bk.jpg -> 100KB backup something-800x800.jpg --> 120 KB optimized original something-800x800.jpg.webp --> 100 KB webp version something-800x800.bk.jpg --> 160KB backup total of 1295 KB space `Hi, these groups are NOT created by LSCWP it just scans/reads/gathers what you have on your site Best regards,` I have regenerate thumbnail plugin. Do you mean that the lightspeed cache plugin just reads its data and optimizes the images? please check my previous reply if you have 5 thumbnails , LSCWP takes that if you have 10 thumbnails , LSCWP also takes that it just scan the database to get what you have , but it will NOT create what you dont have.
