## Overview

Optimize your website's loading speed and user experience by converting standard JPEG images into progressive JPEGs, which render in stages rather than all at once.

## Inputs

- **JPEG Image File** (file): Select JPEG image to convert to progressive
- **Quality (0-100)** (range): Quality of the final progressive JPEG image
- **Scan Count (1-15)** (number): More scans = smoother loading but larger file size
- **Optimize Scans** (checkbox): Optimize scan ordering for better loading performance
- **Use MozJPEG** (checkbox): MozJPEG provides better progressive JPEG compression

## When to use

- When you want images to appear gradually on slow network connections.
- When optimizing website assets to improve Core Web Vitals and page load performance.
- When you need to balance high image quality with efficient file compression.

## How it works

- Upload your standard JPEG image file to the tool.
- Adjust the quality, scan count, and optimization settings as needed.
- Process the file to convert it into a progressive JPEG format.
- Download your optimized image ready for web deployment.

## Use cases

- Improving perceived page load speed for high-resolution hero images.
- Optimizing large product galleries for e-commerce websites.
- Reducing bandwidth usage for mobile users on limited data plans.

## Frequently asked questions

### What is a progressive JPEG?

A progressive JPEG displays a low-quality version of the image immediately, gradually sharpening it as the file finishes downloading.

### Does this tool reduce image quality?

You can control the quality level from 0 to 100; higher values maintain more detail, while lower values reduce file size.

### What is the benefit of using MozJPEG?

MozJPEG is an advanced encoder that provides superior compression efficiency compared to standard JPEG encoders.

### How does scan count affect the image?

A higher scan count results in a smoother transition during loading but may slightly increase the total file size.

### Is there a file size limit?

Yes, the tool supports individual image files up to 50MB.
