When Should You Convert JPG to PNG?
You need transparency support
Placing logos, product cutouts, or icons over colored backgrounds requires PNG to prevent an opaque white rectangular background.
You plan repeated edits & re-saves
JPEG degrades quality cumulatively with each save. PNG preserves full pixel integrity without generational loss.
Your graphics have sharp text & line art
JPG creates noticeable compression halos around sharp edges and typography. PNG renders every stroke with pixel-perfect clarity.
Keep JPG when file size is priority
PNG files are significantly larger. For web galleries, blog hero banners, and social posts, keep photos in JPG or WebP.

PNG employs lossless compression to preserve 100% of pixel and color data, which requires more bytes than JPG's lossy compression. If maximum compression is required, convert to WebP instead.
Never. The conversion is processed entirely in your web browser using HTML5 Canvas. Your files are never transmitted to or retained by external servers.
