よくある質問

Will converting JPG to PNG improve quality?

No. JPG compression artifacts are already baked in. Converting to PNG preserves the current state losslessly but cannot restore lost detail.

Does PNG support transparency?

Yes. PNG supports alpha channel transparency, which JPG does not.

Will the file size increase?

Yes. PNG files are typically larger than JPG because they use lossless compression.

Is there a resolution limit?

No. Images are converted at their original resolution.
