When to use Image Compressor
Your portfolio site is loading slowly because the hero images are 4 MB JPGs straight from Lightroom. Drop them here, nudge the quality slider to 75, and get back files that are typically 60–80% smaller — sharp enough on screen that nobody notices the difference at normal viewing size. Compression runs locally via Canvas: the browser draws each image and calls .toBlob() with your chosen quality setting, so your originals never leave this tab. Batch mode handles an entire folder at once, which matters if you're prepping 50 product photos before uploading to an e-commerce platform. The result is a download-ready file your CMS, email client, or ad platform will accept without hitting a size cap, a slow attachment warning, or a PageSpeed penalty for oversized images.
- Shrink a Lightroom export to fit a 2 MB portfolio site upload limit
- Compress product photos before bulk-uploading to an Etsy or Amazon listing
- Cut image weight before including screenshots in a client-facing PDF report
