Tool usage guide
Optimize your JPEG images for faster web loading and reduced file sizes without sacrificing visual quality. This tool provides advanced compression controls, including MozJPEG support, progressive rendering, and custom quantization tables to help you achieve the perfect balance between file size and image clarity.
Background
A high-resolution hero image was causing slow page load times on a landing page.
Problem
The original 5MB JPEG file was too large for efficient web delivery.
How to use
Upload the image, set quality to 80, enable 'Progressive JPEG' and 'MozJPEG', then process.
quality: 80, progressive: true, mozjpeg: trueOutcome
The image size was reduced to 450KB while maintaining visual quality, significantly improving page load speed.
Background
Newsletter images need to be small to avoid hitting email size limits and to ensure quick loading for subscribers.
Problem
Standard exported JPEGs were too heavy for high-volume email distribution.
How to use
Upload the image, select 'Table 3 (Better compression)' from the quantization table, and enable 'Overshoot Deringing'.
quantTable: 3, overshootDeringing: trueProgressive JPEG loads in stages, showing a low-quality version of the image immediately before sharpening it, which improves perceived performance for users.
Yes, higher compression levels reduce file size but may introduce artifacts. You can use the quality slider to find the optimal balance for your specific needs.
MozJPEG is an advanced encoder that provides better compression ratios than standard JPEG encoders, resulting in smaller files with better visual quality.
This tool is designed to process one JPEG image file at a time.
Trellis Quantisation is an advanced technique that optimizes the compression process to achieve smaller file sizes while maintaining higher visual fidelity.
Outcome
The file size was optimized for email delivery without visible loss of detail, ensuring a smooth experience for subscribers.
