מה זה JPG → PNG?
A JPG to PNG converter transforms compressed JPEG images into lossless PNG format. While JPG uses lossy compression that discards some image data, PNG preserves every pixel exactly. Converting JPG to PNG is essential when you need to add transparency, edit images without further quality loss, or prepare graphics for professional print. Note that converting JPG to PNG does not restore quality lost during the original JPG compression — it preserves the current state losslessly going forward.
למה להמיר JPG → PNG?
There are several specific reasons to convert JPG to PNG. First, editing workflow: every time you save a JPG, it recompresses and loses more quality ('generation loss'). Converting to PNG first means you can edit and save repeatedly without any degradation. Second, transparency: if you need to remove a background or overlay an image on another, PNG supports alpha transparency while JPG does not. Third, screenshots and UI design: PNG's lossless compression produces sharper results for text, icons, and interface elements. Fourth, print preparation: some print services require lossless formats to ensure output quality.

פרטים טכניים
Converting JPG to PNG will increase file size — often 3–5x larger — because PNG uses lossless compression. This is expected and correct behavior. The conversion does not improve the image quality beyond what the original JPG contained. Think of it as putting a JPG in a protective case: no further quality loss, but the existing compression artifacts remain. For web use, consider keeping images as JPG or converting to WebP instead.
