JPG to PNG: Complete Conversion Guide

Converting JPG to PNG is a common need when you require lossless image quality or need to work with transparency. This guide explains when and why to convert, and how to do it securely in your browser.

Key Difference: JPG uses lossy compression (smaller files, some quality loss), while PNG is lossless (larger files, perfect quality preservation) and supports transparency.

Why Convert JPG to PNG?

There are several important reasons to convert JPG files to PNG format:

Preserve Quality During Editing

Every time you edit and save a JPG, it gets compressed again, gradually degrading quality. PNG files don't lose quality when saved, making them ideal for images that need multiple rounds of editing.

Prepare for Transparency

If you plan to remove backgrounds or add transparent areas in photo editing software, you need to work with PNG. JPG doesn't support transparency—every pixel must have a color.

Better for Graphics and Text

PNG handles sharp edges, text, and solid colors much better than JPG. Converting screenshots, diagrams, or images with text to PNG prevents the fuzzy artifacts that JPG compression creates.

Important: Converting JPG to PNG won't restore quality that was already lost during JPG compression. The PNG will perfectly preserve the current state of the image, including any existing artifacts.
