About These Formats
Converting JPG to PNG is the right move when you need a master copy with transparency support, sharper edges on text and graphics, or a working file that will not degrade through repeated saves. JPG uses lossy compression, which bakes in subtle artifacts around fine details and crisp lines. PNG stores every pixel exactly, supports a full alpha channel for transparency, and survives unlimited re-edits without further quality loss. The trade-off is size: expect the PNG to grow roughly three to ten times larger than the source JPG, since PNG cannot discard data the way JPG does. Typical scenarios include preparing logos extracted from JPG screenshots, converting photos that you plan to retouch in Photoshop or Affinity Photo, and producing crisp graphics for slide decks where clean edges matter. WeLoveConvert runs the entire conversion inside your browser, so your image never leaves your device and there is no upload queue. For best results, start from the highest-quality JPG you have; converting a heavily compressed JPG to PNG simply locks any existing artifacts into a pixel-perfect form.
