How to use this tool

  1. Drop your JPEG files

    Drag JPG or JPEG files onto the converter, use the file picker, or paste from your clipboard. Batch conversion is supported.

  2. Let the converter run

    No settings needed — PNG is lossless, so the only option is "best quality." The JPEG is decoded to raw pixels and re-encoded as PNG.

  3. Download your PNG files

    Each PNG preserves the full pixel data from your JPEG. Download individually or as a ZIP. Your files never leave your browser.

  4. Edit without re-compression

    Open the PNG in Photoshop, GIMP, or any editor. You can save changes as PNG repeatedly without any quality loss. Only export back to JPG when you're done editing.
