How to convert JPG to PNG

Why convert JPG to PNG?
Converting JPG to PNG is useful when an app or form only accepts PNG, or when you want to edit an image without adding more JPG compression each time you save.
JPG is the universal photo format. Every device, browser, email client and printer can open it. PNG is a lossless format with transparency support, ideal for logos, screenshots and graphics with sharp edges.
Frequently asked questions
Will converting JPG to PNG improve quality?
No. It prevents further loss when editing, but it cannot restore detail already lost when the JPG was created. The file will usually be larger.
Are my images uploaded to a server?
No. Every image is processed inside your browser using WebAssembly. Nothing is sent over the internet, which also makes it fast and safe for private photos.
Is it really free? Are there limits?
Yes. It’s free with no sign-up, no watermark and no daily limit. Your own device does the work, so there is no server cost per image.
Is image quality affected?
No. PNG is lossless, so the converted image looks exactly like the original.
Does it work on my phone?
Yes. It works in any modern browser on iPhone, Android, Mac, Windows and Chromebook. You can also add it to your home screen and use it offline.
