Convert to PNG when transparency has to survive
The reason to convert a WebP to PNG rather than to JPG comes down to one thing: PNG keeps transparency and JPG destroys it. Both WebP and PNG support an alpha channel, so a logo, icon or cut-out with a transparent background stays transparent through the conversion. Send that same image to JPG and the transparent areas turn solid white, which ruins anything meant to sit on top of another colour.
So if your WebP is a graphic with see-through areas and you need it in a more widely supported format, PNG is the correct destination. If it is a photograph with no transparency and you mainly want a small, universally readable file, JPG is usually the better choice — PNG will be larger for no benefit.
A quick way to decide is to ask what the image is. A screenshot, logo or graphic with sharp edges and flat colour usually belongs in PNG, which keeps those edges crisp and can hold transparency. A photograph with smooth tone and no transparency is almost always better served by JPG, which stores it far more compactly with no visible loss. When you are unsure, converting and comparing the two results takes only a moment, since everything happens instantly on your own device.
Lossless, and therefore larger
PNG is a lossless format, which means the conversion preserves the image exactly as the WebP rendered it, with no additional quality loss. That fidelity is the upside. The downside is size: because PNG does not discard any data, a photographic WebP can grow several times over when it becomes a PNG. For flat graphics and logos the increase is far smaller and often acceptable.
It helps to be clear about what you are optimising for. Choose PNG when you need exactness, editability or transparency and can accept a bigger file. Choose JPG or keep the WebP when a small file matters more than a lossless one. There is no single right answer — it depends entirely on what the image is and where it is going.
A private, local conversion
Every WebP you drop here is decoded and re-saved as a PNG by your own browser, with nothing sent to a server at any point. For images that are private — a saved screenshot, a design you have not published — that is the safe way to convert, because a file that is never uploaded cannot be retained or exposed by a third party.
The tool also handles more than one file at a time. Add a batch of WebP images and each becomes a PNG, ready to download singly or together as a ZIP. Since the work is done on your device, there is no upload step and no per-file size cap beyond your own available memory.
PNG or JPG for your WebP
If you are unsure whether to convert a WebP to PNG or to JPG, the deciding question is whether the image has transparency and whether you will edit it. Transparency or future editing points to PNG, which is lossless and keeps the alpha channel; a plain photograph you just need to open elsewhere points to JPG, which will be far smaller.
Size is the other half of the decision. PNG preserves everything and is therefore larger, sometimes much larger for photos; JPG is compact but flattens transparency to white. Neither is universally correct — pick PNG for fidelity and editability, JPG for a small, universally readable file, and you will rarely regret the choice.
