JPG Optimization Guide

How It Works

Re-encodes your JPG with MozJPEG, an optimized encoder that produces smaller files.

Quality 80

The default quality 80 typically reduces file size by 30-50% with no visible difference.

Quality 60-70

For web thumbnails and previews where smaller size matters more than pixel perfection.

Quality 90+

For high-quality photos where visual fidelity is the top priority.

Frequently Asked Questions

Does optimizing JPG reduce quality?

At quality 80+, the difference is invisible to the naked eye. The file size reduction comes from more efficient encoding, not quality removal.

How much can I reduce JPG file size?

Typically 30-50% at quality 80. Results vary based on the original image and how it was initially compressed.

What encoder do you use?

We use MozJPEG, Mozilla's optimized JPEG encoder that produces the smallest files at any given quality level.

Is this different from JPEG compression?

We use the same JPEG format but with a more efficient encoder. Think of it as smarter compression, not more compression.
