THREE SMALL STEPS

How to jpg to png converter.

  1. Choose your JPG image.
  2. PNG output is selected. Check the dimensions and preview.
  3. Download the encoded PNG file and compare its reported size.

A lossless export of the pixels you have.

Convert a JPG into PNG when you need that file format for a graphics workflow. PNG export does not add another lossy JPG encoding step, but it cannot undo compression already present in the source image.

A JPG starts with an opaque background. Choosing PNG does not automatically remove that background. If you need a transparent cutout, use colour-based background removal or the manual erase brush before exporting.

PNG may produce a much larger file for a photograph. Its lossless encoding has no quality slider in this editor. If size matters more than a PNG requirement, compare JPG and WebP output with the original dimensions before deciding.

A FEW USEFUL DETAILS

Before you download.

Does PNG improve the original photo quality? +

No. It stores the current pixels without a new lossy encoding step, but cannot restore information lost in the original JPG.

Will this make the background transparent? +

No. Format conversion alone does not remove an opaque background. Use the background remover first if a cutout is needed.

Why is the quality slider disabled? +

PNG uses lossless canvas export here. The JPG/WebP quality setting does not affect it.
