How to Convert JPG to PNG

Choose a JPG file, convert it to PNG, and download the result. All processing stays in your current browser.

Changing format does not restore detail

PNG saves the decoded pixels without adding further lossy JPEG compression, but artifacts and detail already lost in the JPG remain. The PNG can be larger because it encodes those pixels losslessly.

When PNG is the useful output

PNG is convenient when a downstream editor or system requires PNG, or when repeated edits should avoid another JPEG save. Converting an existing JPG does not create transparency; every source pixel is already opaque.

Frequently Asked Questions

Does JPG-to-PNG conversion upload the image?

No. The selected JPG and converted PNG are processed only in your browser.

Does PNG conversion improve image quality?

No lost JPG detail is restored. The existing pixels are saved in PNG format.

Why can the output be larger?

PNG uses lossless compression, so photographic images can be larger than JPG files.
