Next.js: Adjust Image Quality on the fly
Next.jsDemo summary
The video demonstrates using the quality prop to dynamically change image compression levels, showing the visual difference between 90% and 5% quality.
Step-by-step
- Add the quality prop to the Next.js Image component
- Set the value to a number between 1 and 100 (e.g., 90 for high quality or 5 for high compression)
- Perform a hard refresh in the browser to see the changes
- Inspect the image URL to verify the 'Q-' parameter matches your specified value
Options
- Manually adjust the quality by editing the 'Q-' parameter directly in the ImageKit URL
Watch out for
- The default image optimization quality is 80 if the quality prop is not configured
Tips
- Use a quality of 75 as a good alternative default for a balance of performance and visual fidelity
- Don't always use full quality images; lower quality (even 5%) can be sufficient depending on the use case
Highlights
“the quality prop is quite powerful because you can adjust it on the fly dynamically”
