Compress JPG images before uploading to your CMS. Smaller images mean faster page loads, better Core Web Vitals, and improved SEO rankings.
Compress photos before emailing to stay under attachment limits. A batch of 20 vacation photos can go from 80MB to under 20MB.
A photo library of 10,000 JPG files at 5MB each takes 50GB. Compressing to 80% quality reduces that to ~15GB with no visible difference.
Social platforms re-compress uploads anyway. Pre-compressing with Picmal gives you control over quality and avoids double compression artifacts.
