Why Convert JPG to PNG?
JPEG is the go-to format for photographs and web images thanks to its efficient lossy compression. However, every time you re-save a JPEG, it loses a tiny bit more detail. Converting to PNG freezes your image in a lossless format, meaning no further quality loss will occur regardless of how many times the file is opened and saved. PNG also supports alpha transparency, making it essential for logos, icons, overlays, and any graphic that needs to sit on varying backgrounds. If you plan to edit an image extensively, converting from JPG to PNG first ensures each save cycle does not introduce new compression artifacts.
JPG vs PNG Comparison
JPEG uses lossy compression that discards imperceptible visual data, producing small files ideal for photographs. PNG uses lossless compression that preserves every single pixel, resulting in larger files but perfect fidelity. JPEG does not support transparency while PNG supports full alpha channel transparency. For photography and web delivery where small size matters, JPEG wins. For graphics, screenshots, text-heavy images, and anything requiring transparency or future editing, PNG is the superior choice. A typical 5 MP photo might be 1 MB as JPEG but 8-12 MB as PNG, so be mindful of file size increases when converting.
