Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Convertiring a JPEG to PNG is useful when another application expects PNG, when you need to continue editing in a lossless format, or when a workflow specifically requires a .png file. The conversion preserves the pixels that exist in the JPEG; it cannot recover detail already discarded by JPEG compression.
Compare file size after conversion. Photographs often become much larger as PNG files, so converting simply because “PNG is higher quality” can create a heavier file without adding visible information.
A design tool that only accepts PNG can use a converted product photo, but keep the original JPEG too so you are not forced to use the larger PNG everywhere.
If your real goal is a smaller photographic file, compression or WebP may make more sense than JPG-to-PNG conversion.
Example: convert a JPG photo to PNG when you need a lossless PNG file for editing, graphics work, or a workflow that requires PNG input.

The tool creates a new output for you to review. Keep the original until you have checked the result, especially when layout, image quality, metadata, or page order matters.

Check the input format and review the output before replacing an original file or using the result in an important workflow.
Démarrer with a clean input, use the simplest settings that meet your goal, and compare the result with the original before you download or reuse it.
