什麼是JPG轉PNG轉換工具？
從JPG轉換為PNG並不會恢復在JPG壓縮中遺失的品質：那些資料早已消失。但當你需要繼續編輯圖片，又不希望每次儲存都累積JPG雜訊時，PNG輸出就很有用。
常見使用場景
Preparing a JPG photo for editing in a tool where you will re-save repeatedly, avoiding JPG generation loss on each save.
Supplying an image to an app, CMS, or printer that accepts PNG but rejects or mishandles JPG uploads.
Converting a logo or icon that was mistakenly exported as JPG into PNG before placing it on a layered design.
Producing a clean PNG copy for screenshots or diagrams that need crisp edges without JPG blocking.
Standardizing a folder of mixed images to PNG one at a time for a build pipeline or asset library.
Sharing an image where you want a lossless master copy rather than a recompressed JPG.
