JPG to PNG

What Is the JPG to PNG Converter?

The JPG to PNG Converter changes a JPG image into a PNG image in your browser. JPG is a lossy format designed for photographs, while PNG is a lossless format that is better suited to graphics, logos, screenshots, and images that will be edited again. Converting to PNG does not restore detail that JPG compression already discarded, but it avoids adding another round of lossy compression when you save or edit the image further.

How to Use the JPG to PNG Converter

1. Drop a JPG image onto the workspace upload area, or click Choose Image to browse for one. The workspace also lists PNG, WebP, GIF, BMP, and SVG as accepted inputs.
2. Check the Quality slider, which starts at 80.
3. Click the Process button.
4. Review the converted image in the result panel.
5. Download the PNG file to your device.

Worked Example

Choose a JPG photograph, leave the Quality slider at its observed default of 80, and click Process. The tool produces a PNG version of the same image at the same dimensions for download. Because PNG is lossless, the converted file is often larger than the original JPG, especially for photographs. That size increase is expected: the conversion preserves the decoded pixels rather than compressing them the way JPG does. If you need a smaller file rather than a lossless one, a JPG or WebP output is the better choice.

Limitations

• Converting JPG to PNG does not restore detail lost by JPG compression, and it does not add transparency. A JPG has no transparent areas, so the PNG output is fully opaque.
• PNG files are often larger than the equivalent JPG, so this conversion is not a file-size optimisation.
• The workspace converts one image at a time; there is no batch mode.
• The only conversion control in the workspace is the Quality slider. There are no resize, crop, rotation, or background-removal controls in the workspace.
• The Quality slider has limited meaning for a lossless PNG output; it cannot improve on the decoded pixels of the source JPG.
• Very large images can be slow to convert and may be limited by your browser and device memory.

Frequently Asked Questions

Will converting JPG to PNG improve image quality?

No. The conversion preserves the pixels that are decoded from the JPG, including any compression artefacts. Its value is preventing further lossy compression when you edit, annotate, or re-save the image.

Why is the PNG file bigger than my JPG?

PNG uses lossless compression, so it stores the full decoded pixel data instead of discarding detail the way JPG does. For photographs, that usually produces a larger file.

Can this tool make the background of my JPG transparent?

No. A JPG has no transparency information, so the converter cannot know which pixels should become transparent. Background removal is a separate editing task.

Does the tool upload my image to a server?

No. Conversion happens in your browser on this page. Your image is not sent to a server by this tool for conversion.
