JPG to PNG Converter

Convert JPG and JPEG images to PNG in one step. The PNG keeps every pixel of your JPG exactly, with no further compression loss. Conversion happens in your browser, so your image is never uploaded.

When to convert JPG to PNG

  • Editing in several rounds: each JPG re-save loses a little more detail. Working in PNG stops that generational loss.
  • Software or forms that require PNG: some design tools, app stores and upload forms only accept PNG.
  • Preparing for transparency: if you plan to remove the background later, PNG can store the transparent areas; JPG can't.
  • Graphics saved as JPG by mistake: converting keeps them from getting worse with further edits.

Transparency

Converting doesn't make any part of the image transparent. A JPG always has a solid background, and the PNG will look exactly the same. PNG simply makes transparency possible for later edits.

Quality and file size

The PNG is a pixel-perfect copy of the decoded JPG. It won't look sharper, and any JPG artefacts (blockiness or halos around edges) stay as they are. Because PNG stores every pixel without lossy compression, expect the file to be larger, often much larger for photos. If file size matters more than lossless editing, keep the JPG or compress the image instead.

Going the other way? Convert PNG to JPG to get a smaller file from a PNG. Only need a .jpeg file renamed to .jpg? Use JPEG to JPG; to put JPGs in a document, JPG to PDF.

Privacy: your image stays on your device

The JPG is decoded and saved as PNG by your own browser. No copy of your image is sent to a server, and the converted file is created on your device.

Frequently asked questions

Does converting JPG to PNG improve image quality?

No. JPG compression permanently removes some detail when the JPG is saved. Converting to PNG keeps the image exactly as it is now and prevents any further loss when you edit and re-save it, but it can't bring back detail that's already gone.

Will the PNG have a transparent background?

No. JPG images have no transparency, so the converted PNG has the same solid background as the original. Removing a background is a separate editing step; once removed, PNG can store the transparency.

Why is the PNG file bigger than the JPG?

PNG uses lossless compression, which stores every pixel exactly. Photos contain lots of subtle variation that lossless compression can't shrink much, so a photo as PNG is often several times larger than the same photo as JPG. That's normal.

What's the difference between JPG and JPEG?

None. They are the same format; .jpg became common because older versions of Windows only allowed three-letter file extensions. This converter accepts both.

Can I convert several JPGs at once?

This converter handles one image at a time: select the next image after downloading and it converts immediately. To convert a whole batch, the bulk image resizer can save many images as PNG in one go and download them as a ZIP.

Is my image uploaded during conversion?

No. Your browser decodes the JPG and encodes the PNG locally on your device. The image is not uploaded or stored anywhere.
