JPG to PNG Conversion

JPG files use lossy compression, which means they sacrifice some image quality to achieve smaller file sizes. Every time you edit and save a JPG, it loses a bit more quality. JPGs also don't support transparency, so every pixel must have a color value.

PNG files use lossless compression. This means you can edit and save a PNG as many times as you want without losing any quality. PNGs also support transparency, allowing parts of your image to be see-through. This makes PNG ideal for logos, graphics, and any image that needs to be layered over other content.

Frequently Asked Questions

Why should you convert JPG to PNG?

JPG employs lossy DCT (Discrete Cosine Transform) compression that permanently discards image data each save cycle - a phenomenon called generation loss. After 3-5 edit-and-save cycles, visible quality degradation appears: color banding in gradients, blockiness in detailed areas, and loss of fine textures. JPG also lacks alpha channel support, forcing transparent areas to render as solid white or black backgrounds, making it unsuitable for logos, overlays, or layered design work. Converting to PNG eliminates these limitations through lossless DEFLATE compression that preserves every pixel perfectly, regardless of how many times you edit and save. PNG adds full 8-bit alpha transparency for smooth, gradient-edge cutouts and supports 24-bit true color. Essential when extracting graphics from photos, creating website elements, designing logos, or any workflow requiring multiple editing iterations without quality loss.
