When PNG is the useful destination
PNG is useful when you need a broadly supported lossless container for decoded pixels, repeated editing, or workflows that require a .png file.
Turn a static JPG or JPEG into a PNG locally in your browser, with no upload or sign-up.
PNG is useful when you need a broadly supported lossless container for decoded pixels, repeated editing, or workflows that require a .png file.
A JPG has already discarded information during its earlier encoding. Saving those decoded pixels as PNG prevents new JPG loss in this step, but it cannot recreate detail or transparency that is no longer present.
Use the general converter to choose any supported JPG, PNG, or WebP direction.
Open the general converter →Format behavior, transparency, file size, and what stays on your device.
No. A PNG file can support transparency, but conversion cannot infer which JPG pixels should become transparent. The visible JPG background remains part of the image.
It does not restore quality already lost in the JPG. The PNG stores the decoded result without another lossy JPG save, so it is useful for format compatibility rather than quality recovery.
PNG uses lossless compression for the decoded pixels, while JPG is designed for lossy photographic compression. A larger PNG output is therefore normal for many photographs.
Yes. JPG and JPEG are two extensions for the same supported image format, and this page accepts both.
No. Your original and processed images stay inside your browser and are never uploaded to our server. Refreshing or closing the page clears the working image data from the browser. Files you download remain on your device until you delete them.
