주요 기능
Add transparency
JPG has no alpha channel; after conversion you can pick a background colour, including transparency.
Sharper text and lines
PNG uses lossless compression, so icons and line art stay crisp after conversion.
Batch processing
Drop in many JPGs or a whole folder and convert them together.
활용 사례
Interface icon assets
Convert design icons to PNG so they blend into any background.
Images needing alpha
JPG cannot store transparency, so add an alpha channel after converting.
자주 묻는 질문
Will the file get bigger after converting to PNG?
Usually yes. JPG is lossy while PNG is lossless, so files often grow two to five times. For smaller files consider WebP instead.
Why is my image not transparent after conversion?
JPG contains no transparency information, so conversion can only add a background — it cannot recover transparency that was never there. Start from a PNG or WebP source instead.
