원본 / Source: 투명 PNG / transparent PNG 출력 / Output: JPEG, 투명 영역 흰색 / transparent area becomes white
Steps to verify
- Check for transparent areas.
- Inspect the JPEG background.
- Compare edges on the final background.
How to interpret the result
Conversion re-encodes rather than just changing an extension. Background fill and lossy-quality differences can occur together.
Deciding what to do next
Review PNG or WebP if transparency is needed. Converting the JPEG back to PNG does not automatically restore transparency.
Feature scope
Re-encode supported PNG, JPEG and WebP in the browser. JPEG fills transparency with white; review actual output support without assuming original metadata or animation is retained.
Frequently asked questions
Does converting back to PNG restore the original?
Lost detail and original transparency are not automatically restored. Keep the source.
