How to Use JPG to PNG Converter

To convert JPG images to PNG, drag and drop your JPG or JPEG files onto the upload area or click to browse. Multiple files can be added for batch conversion. The conversion runs entirely in your browser — no server upload is required.

Each image is converted and the file sizes before and after are displayed. PNG files are larger than JPG but use lossless compression, preserving every pixel exactly. Download individual PNG files or all at once. This is useful when you need images with transparent backgrounds or lossless quality for editing.

Frequently Asked Questions

Why would I convert JPG to PNG? expand_more

PNG uses lossless compression, making it better for images that will be edited further, need transparent areas, or contain text and sharp edges that JPG compression would blur.

Does converting JPG to PNG improve quality? expand_more

No. Converting a JPG to PNG does not recover quality lost during JPG compression. The existing quality is preserved without further loss, but the conversion cannot add detail that was already removed.

Will the PNG file be larger than the original JPG? expand_more

Yes. PNG files are typically larger than JPG for the same image content because PNG stores pixel data without lossy compression. This is expected and is the trade-off for lossless storage.

Can I add transparency to the image during conversion? expand_more

This converter preserves the image as-is in PNG format. To add transparency, you would need an image editor after conversion.

Are my JPG files sent to a server? expand_more

No. All processing happens locally in your browser. Your image files are never uploaded anywhere.
