The short version

What is JPG to PNG Converter?

SlapMyWeb's JPG to PNG converter copies the decoded JPEG image into PNG format in your browser.

PNG can store transparency, so you can optionally match a chosen color and make matching pixels transparent. This does not restore image detail already lost to JPEG compression.

Step by step

How to use JPG to PNG Converter

  1. 1

    Optionally enable color transparency

    Toggle "Make color transparent" if you want to remove a specific background color. Pick the color using the color picker and adjust the tolerance slider to control how closely pixels must match.

  2. 2

    Drop or select JPG images

    Drag and drop multiple JPG/JPEG images or browse for files. You can also paste an image from your clipboard. Each file is limited to 80 megapixels.

  3. 3

    Download your PNG files

    Review the converted files showing original and new sizes. Download images individually by clicking the download icon, or use "Download all" to save the entire batch at once.
