JPG vs PNG: What's the Difference?

JPG (also written as JPEG) is a lossy format optimized for photographs — it achieves small file sizes by discarding some image data. PNG is a lossless format that preserves every pixel, supports transparent backgrounds, and is better suited for graphics, logos, and screenshots.

The main reasons to convert JPG to PNG:

You need a transparent background (JPG doesn't support it)

You want to edit the image without quality loss on repeated saves

The image contains text or sharp edges that look better in PNG

You need an exact pixel-perfect copy without compression artifacts

Tips for JPG to PNG Conversion

File size will increase: PNG files are larger than equivalent JPGs because PNG is lossless. Don't be surprised when your 200KB JPG becomes a 1MB PNG.

Quality won't improve: Converting JPG → PNG doesn't restore quality lost during the original JPG compression. The PNG simply stores the same pixels without further loss.

Use for editing: If you plan to edit an image multiple times, convert it to PNG first. Each save of a JPG degrades quality; PNG doesn't have this problem.

Screenshots: Screenshots are naturally PNG or can be converted to PNG for the sharpest text rendering.

Frequently Asked Questions

Will converting JPG to PNG make the image look better? No. The conversion stores the existing pixel data without further loss, but it can't recover detail that JPG compression already removed. Why is the PNG file so much larger than the JPG? PNG stores every pixel exactly as-is, while JPG discards some data to achieve smaller sizes. This is expected and normal. Can I convert PNG back to JPG? Yes. Use the Convert Image tool to convert in the other direction.
