Steps to use JPG to PNG Converter

Transparency & Color Handling

JPEG is a lossy RGB format with no alpha channel. Converting JPG to PNG does not invent missing transparency—edges remain opaque. Use this path when you need a lossless intermediate for further editing or a packaging pipeline that only accepts PNG, not because you expect “instant cutouts.”

Color banding from prior JPEG compression can become more visible in PNG; regenerate from the original camera or source file when print quality matters.

When JPG→PNG Helps (and When It Doesn’t)

Typical wins and non-wins:

• Helpful: preparing assets for tools that reject JPEG, or building sprites that may gain alpha later
• Helpful: avoiding further JPEG generational loss during multi-step edits
• Not helpful: shrinking file size (PNG of a photo is usually larger than the JPEG)
• Not helpful: creating transparent logos from JPEGs without a separate mask/background removal step

Practical Limits

Very large multi-megapixel photos increase memory during decode. Prefer reasonable web dimensions before conversion when you hit timeouts. Keep EXIF privacy needs in mind—downstream tools may strip or preserve metadata differently.
