Compress Images for the Web Without Losing Quality (Free)
Shrink JPEG/PNG files in your browser to speed up your site. Free, private, no upload.
Large images slow down pages and waste bandwidth. FreeToolBox compresses JPEG and PNG right in your browser using the Canvas API — you pick a quality slider (10–100%), see the before/after size, and download. Nothing is uploaded. Great for bloggers, indie hackers, and anyone optimizing a GitHub Pages site or portfolio.
FreeToolBox — free forever, private by design. Support with a tip.
