About this tool

PNG to JPG suits a photograph that was saved as PNG and is larger than it needs to be. It is the wrong move for a flat logo with transparency. Edges of text may soften. The JPEG is encoded here.

PNG to JPG stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.

  • No upload: the PNG to JPG encode uses this browser, not a conversion API.
  • Speed: the file does not travel to a server and back, so the wait is only the work itself.
  • Quality: the original is kept when the new file would be worse or is not actually smaller.
