JPG to PNG Converter
Turn a JPG into a lossless PNG right in your browser. Handy when a tool insists on PNG, or you want a clean copy to edit without losing any more detail.
Everything runs in your browser — your image is never uploaded, sent to a server, or stored. Nothing leaves your device.
How it works
Choose your JPG and the tool re-encodes it as a lossless PNG — there's no quality slider here, since PNG doesn't work that way. The width and height stay exactly the same; only the format changes. Your download keeps the original file name, just with a .png ending.
When to use it
Use this when a tool or form requires a PNG, or when you want to keep editing an image losslessly from this point on without adding more compression artifacts. Just know it won't undo any quality already lost when the file was saved as a JPG, and the resulting PNG will likely be bigger than the original.
Frequently asked questions
Will converting to PNG bring back detail my JPG lost?
No. PNG is lossless going forward, but it can't undo compression that already happened. It just wraps the current pixels losslessly from here on.
Will the PNG file be smaller than my JPG?
Usually no — it's typically larger. PNG doesn't compress photographic detail as tightly as JPG does, so expect a bigger file size.
Is my image uploaded anywhere?
No. The conversion happens entirely in your browser using a canvas element. Your file never leaves your device.
