Bloomlight Free tool
Image Optimizer
Quickly and privately convert your images to web-performant ones right in your browser. Drop an image and download a dramatically smaller file for faster page load times.
High-density screens (Apple Retina, most phones) pack 2× or 3× the physical pixels into each CSS pixel. An image shown in a 720px-wide slot on a 2× screen is actually drawn across 1440 pixels — so to look sharp it needs roughly twice the width you'd expect.
Pick a width around 2× the largest size the image will be displayed at on your site.
With a fallback — only for pre-2020 browsers
Upload the downloaded .webp and point the src at where it actually lives — the snippet only fills in the file name.
Your whole site, automatically.
Bloomlight finds every oversized image across every page, compresses them, and tells you exactly what to replace — without you having to check manually.
Stop fixing images one at a time.
Bloomlight scans every page on your site and surfaces every oversized image — with fix instructions ready.
