When this helps
Useful when an upload form needs JPG, a graphic needs PNG transparency or a website uses WebP. This tool changes the encoded format while keeping the pixel dimensions.
How it works and its limits
JPG is useful for photographs and always has an opaque background. PNG supports transparency and lossless pixel encoding, while WebP supports transparency and adjustable lossy quality here.
Changing a JPG to PNG cannot restore information already lost in the JPG. Browser encoders may produce a larger result, so compare the reported sizes rather than relying on the extension.
Only static JPG, PNG and WebP files are supported. HEIC, AVIF, SVG, GIF and animated PNG/WebP are not accepted in this version. Source metadata is not retained.
Useful details
Is WebP supported by every browser?
Current browsers commonly support it; if encoding is unavailable the tool reports it instead of renaming a PNG as WebP.
Will PNG make a JPG sharper?
No. It cannot reconstruct discarded detail.
What happens to transparency in JPG?
It is composited onto your chosen background color.
