How it works
PNG (Portable Network Graphics) is a raster image format created in 1996 as an open, patent-free alternative to GIF. It uses lossless compression, meaning every pixel is preserved exactly as in the original — no detail is ever discarded. PNG also supports full alpha-channel transparency, making it the go-to format for logos, icons, user interface elements, and any graphic that needs to be placed over variable backgrounds.
The downside of lossless compression is file size. A photograph saved as PNG can easily be 5 to 10 times larger than the same image saved as JPG at high quality. That extra weight increases page load time, eats into email attachment limits, and consumes more storage on phones and cloud drives. When pixel-perfect transparency is not needed, converting to JPG is the most practical way to reclaim disk space without visible quality loss.
Quick & easyPrivacy & security
Your images are never uploaded to any server. The entire PNG-to-JPG conversion runs locally in your browser using the HTML5 Canvas API. This means your files never leave your device — whether you are converting personal screenshots, confidential business documents, or sensitive design assets.
Because processing is 100% client-side, there is no file-size upload limit imposed by a server, no waiting for a round-trip, and no risk of your data being stored or shared. Once you close or refresh the page, all converted files are purged from browser memory.
