How to use JPG ↔ PNG Converter
- Select a JPG or PNG image.
- Choose JPG or PNG as the output format. Adjust quality for JPG.
- Convert and download the new image.
A closer look
Choose the format that fits your next task. JPG is often efficient for photographs, while PNG is lossless and supports transparency, making it useful for screenshots and graphics. Conversion changes the file encoding; changing an extension by hand does not. Converting a compressed JPG to PNG will not restore details lost during earlier compression.
A practical example
Convert a transparent PNG to JPG for an application that accepts photos only. The transparent areas become white; choose PNG when you need to keep transparency.
A useful tip
Choose PNG for sharp text or transparent artwork. Choose JPG for photographs where a smaller file matters more than perfect pixel preservation.
Good questions. Simple answers.
Will PNG restore JPG quality?
No. It preserves the decoded pixels without another lossy compression step, but cannot reconstruct previously discarded detail.
Why did my transparent background turn white?
JPG has no alpha channel. Toolzafi fills transparent pixels with white when exporting JPG.
