About the JPG to PNG

Some editors, slide templates and print services ask for PNG, and PNG is a safe format to keep editing in because saving again never loses quality. This tool turns a JPG into a PNG in your browser with no settings to choose: the pixels are copied as they are and written to a lossless file, ready to download as soon as it loads.

What you can do

  • Drop a JPG and get a PNG straight away, without picking options.
  • Keep exactly the same width, height and colours as the original.
  • See how the file size changes before you download.
  • Rename the PNG on the download screen.

When it works best

  • Uploading to a tool or template that only accepts PNG.
  • Making a working copy of a photo that you plan to edit and save many times.
  • Preparing an image for software that handles PNG more reliably than JPG.

Things to know

  • The JPG never leaves your computer; the browser does the conversion.
  • Expect the PNG to be larger, often several times, because lossless storage of a photo takes more space.
  • Converting does not undo JPG compression. Blockiness already in the file stays.
  • The background does not become transparent, since the JPG had no transparency to keep. For a smaller modern file, try Convert Image with WebP.

No. Existing compression artefacts are copied into the PNG unchanged.

No, the JPG had no transparency to carry over.
