Examples

1. Optimizing Website Hero Images

Web Developer
Background
A high-resolution hero image was causing slow page load times, negatively impacting SEO rankings.
Problem
The original 12MB file was too large for efficient web delivery.
How to Use
Upload the image, set the quality to 75, and enable 'Progressive JPEG' for faster rendering.
Example Config
quality: 75, progressive: true
Outcome
The file size was reduced to under 500KB while maintaining high visual fidelity, significantly improving page load speed.

2. Preparing Email Attachments

Freelance Photographer
Background
The photographer needed to send a preview gallery to a client via email, but the files exceeded the attachment limit.
Problem
Individual images were too large to send as a single batch.
How to Use
Upload the images and set the quality to 60 to reduce file size without sacrificing too much detail.
Example Config
quality: 60, keepMetadata: false
Outcome
The images were successfully compressed to a size suitable for email, allowing the client to view the previews without downloading massive files.

FAQ

What is the best quality setting for web images?

A quality setting between 70 and 85 is generally recommended as it provides a significant reduction in file size with minimal visible loss in quality.

Does changing the quality affect the image resolution?

No, this tool only adjusts the compression level (quality) of the JPEG data; the pixel dimensions (width and height) remain unchanged.

What does the 'Progressive JPEG' option do?

It creates an image that loads in stages, showing a blurry version first that sharpens as the file downloads, which is ideal for web performance.

Will I lose my EXIF data?

By default, metadata is removed to save space. If you need to keep camera settings or location data, ensure you check the 'Keep Metadata' option.

Is there a limit to the file size I can upload?

The tool supports individual JPEG files up to 50MB.
