Convert JPG to PNG instantly

JPG is great for photos, but it is a lossy format. Every time you re-save a JPG, quality degrades a little. PNG is lossless, so converting to PNG locks in the current quality and prevents further degradation. PNG also supports transparency, which JPG does not. This converter draws your image onto an HTML Canvas element and exports it as PNG. The entire process happens in your browser using the Canvas API. Your image is never uploaded anywhere.

The main reason people convert JPG to PNG is to stop the quality degradation cycle. If you are editing an image repeatedly, saving and re-saving in JPG introduces artifacts each time. Converting to PNG first gives you a stable base. The tradeoff is file size. A 300 KB JPG might become 1.5 MB as PNG because lossless compression stores every pixel exactly. For web use where file size matters, that can be a problem. For editing and archiving, the quality preservation is worth it.

Common scenarios include preparing images for design tools that prefer lossless formats, converting screenshots that need to stay sharp, and creating assets for applications where transparency support is needed later. If your goal is smaller file sizes for the web instead, consider JPG to WebP which gives you 25-35% savings over JPG. Need to go the other direction? PNG to JPG shrinks files significantly when lossless quality is not critical.
