Quality: 80%

Lower quality = smaller file. 80% is a good balance. All processing is local — no upload.

Image Compression Guide

Unoptimized images are the #1 cause of slow websites — images account for an average of 50-65% of a webpage's total weight. Google's Core Web Vitals penalizes sites with large images, directly impacting SEO rankings. Compressing a 2MB photo to 200KB reduces load time by 90% with barely perceptible quality loss.

The key is choosing the right format: JPEG for photos (lossy but 10:1 compression ratio), PNG for graphics with transparency, WebP for everything (25-35% smaller than JPEG/PNG at same quality), and AVIF for the cutting edge (50% smaller than JPEG).

Resize before compressing — a 4000px-wide photo displayed at 800px is wasted bandwidth
JPEG quality 80% is the sweet spot: large file size reduction with minimal visible difference
Compress client-side when possible — keeps sensitive images off third-party servers
