Convert JPG to PNG Online: Create a PNG Image Copy
A JPG-to-PNG converter can prepare an image for software or a workflow that accepts PNG files. The conversion changes the file format, but it does not recreate detail lost through earlier JPEG compression.
Convert a JPEG image to PNG
- Choose a JPG or JPEG image from your device.
- Check that the correct image is shown in the preview.
- Select Convert and wait for the browser to create the PNG copy.
- Download the PNG and confirm the file opens in the destination application.
- Keep the JPEG source if you may need the original file.
What changes during JPG-to-PNG conversion
The image is decoded and exported in PNG format. This does not restore original quality or add transparency to a JPEG that did not contain transparent pixels.
When PNG is useful
PNG can be useful for graphics, screenshots, interface assets and workflows requiring PNG input. Photographs may produce larger PNG files than JPEG.
What the conversion does and does not do
The tool decodes the JPG and saves the same picture in the PNG format. It does not bring back detail that the JPG compression already removed, it does not make the picture sharper and it does not create transparency, because a JPG has none. The point of the conversion is the format, not the quality.
Why people still need PNG
Some forms, design tools and programs accept only PNG. PNG is also the better format for further editing of graphics and screenshots, because saving a PNG again does not lose detail, while every new JPG save can. If you only want to show a photograph on a page or send it, the JPG is usually the smaller and the better choice.
File size and next steps
A photograph saved as PNG is often several times larger than the JPG it came from. Compare the two sizes, and if the PNG is too large for an upload limit, keep the JPG, or reduce the pixel size first with Image Resizer. If you need a transparent background you must remove the background in an editing program, because this tool cannot do that.
Frequently asked questions
Does converting JPG to PNG improve image quality?
No. It changes the container/encoding format; it cannot recover detail already lost in the JPEG source.
Will the PNG have a transparent background?
Not automatically. A JPEG has no transparency channel to preserve.
Does converting JPG to PNG improve the quality?
No. It only changes the format. It cannot restore detail that is already lost.
Why is the PNG so much bigger?
PNG keeps every pixel without the lossy compression a JPG uses, so photographs take more space.
Can I get a transparent background this way?
No. Use an editing program to remove the background.
