Why Compress to 150KB?
Blog thumbnail images on WordPress, Ghost, and Medium render at dimensions where 150KB captures full detail without slowing down archive and category pages. Amazon and eBay product listing images in grid view display at sizes where 150KB offers excellent quality and fast load times across devices. Social media profile avatars on LinkedIn, Twitter/X, and Discord are stored and served at resolutions where 150KB provides sharp, artifact-free results even after the platform's own re-encoding. Google Business Profile photos also perform well at 150KB — fast loading in Maps results while retaining enough detail to represent storefronts and products clearly.
Tips for Compressing to 150KB
For blog thumbnails, compress after cropping to the exact aspect ratio your theme uses (typically 16:9 or 4:3) to avoid wasting bytes on areas that get cropped by CSS.
Product listing images on white backgrounds compress significantly better than lifestyle shots at 150KB — consider separate background removal before compression.
If uploading to LinkedIn or Twitter, a 150KB source gives the platform's encoder plenty of data to produce a clean result.
