JPG vs PNG

PNG is useful for editing, screenshots, line art, and graphics workflows that prefer a lossless output. JPG is usually better for photographs and smaller attachments.

This converter changes the encoding while keeping the JPG's original width and height. It does not recreate detail that was already lost in the JPG.

JPG to PNG does not create transparency

A JPG has no transparency channel. The PNG output is still opaque because there are no transparent pixels in the source for the conversion to recover.

  • Use PNG when the next app or upload form specifically requires PNG.
  • Use PNG for graphics and screenshots when you want to avoid another lossy JPEG encode.
  • Keep the original JPG as well because PNG output can be larger without improving its detail.

Limitations

  • Converting JPG to PNG does not restore JPEG detail that was already discarded by compression.
  • PNG output can be larger than the original JPG because PNG uses a different encoding model.
