JPG to PNG

Convert JPG images to lossless PNG files.

Processed locally in your browser — your file is not uploaded.
How is this private?

Processing happens in this browser tab, so files are not uploaded to Metyris for processing. Reloading or closing the page clears working data, though your browser may retain temporary files or downloads. Very large files can exceed available browser memory.

How to use JPG to PNG

  1. Select a JPG image.
  2. Review its dimensions and preview.
  3. Convert and download the PNG.

Does conversion recover lost detail?

No. PNG prevents further lossy encoding but cannot restore detail already lost in the JPG.

No sign-up is required. The calculation or transformation happens in this browser tab and the result is available immediately.

Good to know

Does the original file change?+

No. The result is a new download.

What happens to metadata?+

Canvas processing removes metadata and animated inputs become a still frame.

Is my content uploaded?+

No. Processing happens in this browser tab and the tool does not send your content to a server.
