Does Converting JPG to PNG Improve Quality?
A common myth says converting JPG to PNG “upgrades” the image. PNG can store pixels losslessly later, but it cannot recover information JPEG already discarded.

What JPEG already removed
JPEG compression discards detail based on quality settings. Those losses are permanent in the decoded pixels.
What PNG actually does
After decode, PNG can save those pixels without further JPEG-style loss. That is useful for editing workflows, not for restoring a cleaner original.
When conversion still helps
Convert when a tool requires PNG, when you want lossless re-saves of the current pixels, or when preparing assets for editors that prefer PNG. Use /tools/jpg-to-png.
